Winter bumblebees and the Keith Richards red admiral

The Christmas weather had been poor but Boxing Day (December 26^th) was mild, clear and bright and the seafront at Paignton in south Devon was thronged with people promenading in the sunshine and as busy as I have ever seen.  Some had also come to watch “Walk into the sea” a charity event where hardy souls, often in fancy dress, splash in the cold waters of Torbay.

It was good to see all the people enjoying the weather but I was here for a different reason. I left the crowds behind and headed past the little harbour towards Roundham Head, a promontory that protrudes into the waters of Torbay.  Here I found Roundham Head Gardens, public gardens built on the sloping, south-facing side of this headland where narrow paths zig zag up and down the cliff face between borders planted with many exotic species.  Some of these plants flower throughout our winter providing an unusual micro environment.

Scorpion vetch (Coronilla valentina) (see picture at the head of this post), a native of the Mediterranean, is one of the plants that flourishes here and the low winter sun seemed to accentuate the lemon-yellow colour of its pea type flowers.  In the same border overlooking the sea I also found some bergenia flowers, an almost psychedelic pink in this low light.

It wasn’t just the humans who had been drawn out by the mild sunny weather, there were also a number of insects about.  A small furry bumblebee had discovered the scorpion vetch and was systematically visiting each flower to feed.  Her black, white and brownish-yellow banding stood out like a furry bar code and she carried a yellow lump of sticky pollen on each rear leg.  She was most likely a worker buff-tailed bumblebee (Bombus terrestris) and I watched her track across the clump of flowers.

Eventually, I had to move to the far side of the border to get a better view of the small bee, but I hadn’t noticed the large queen bumblebee feeding on the bergenia.  She objected to my presence and flew away buzzing loudly after circling closely around my head.  Was this a warning or was she just having a look?  I only got a quick glimpse but she looked like a buff-tailed bumblebee queen, our largest bumblebee species.  Later, I got a much better view of one of these huge insects basking in the sun on an old stone wall.  This one was the size of the distal section of my thumb, very furry and with clear black and orange-brown bands and a brownish tail.

As I wandered about the enclosed paths, I encountered more small buff-tailed bumblebees, often feeding from the slate blue flowers of the rosemary that grows well here.  Most of these were carrying pollen of different colours, white, yellow or red, so they were all workers.

This winter bumblebee activity is probably a consequence of the mild marine environment in these gardens and the profusion of flowers that grows here even in the lowest months.   The worker bumblebees will be supporting nests begun by queens a few months ago, whereas the queens I saw may be preparing to set up new nests that will last across winter.

A return to the first border gave another surprise:  a red admiral butterfly basking on bergenia having been tempted out by the warm sun. As I watched it flexing its wings, another floated past my shoulder before disappearing.  I shared my picture of the red admiral on social media and one commenter (see below for details) pointed out that although this survivor from the summer still had bright colours, it now looked very worn and suggested that this was the Keith Richards of red admirals!

Seaside Storms and bumblebees

By the end of October, I had begun to feel that autumn was running away from me.   Then came the announcement that a second lockdown would be imposed.  So, one afternoon at the beginning of November, I decided I needed to get outside and went to Roundham Head in Paignton, one of my favourite nearby nature haunts.  Roundham Head sits roughly in the centre of the semi-circular arc of Torbay and from the southern side of the promontory there are fine long views around to Brixham with its harbour, small boats and breakwater. 

My main reason for visiting, though, was the public garden built on the southern slopes of the headland.  Here, zig zag paths meander up and down between borders stocked with tender and unusual plants many originating in warmer climates but thriving here in the mild maritime conditions of Torbay.  Many of these plants continue to flower here in autumn and winter.

I started at the top of the public garden looking south west with the low sun creating a dazzling mirror across the wet, low-tide sand at Goodrington where dogs and their owners rushed back and forth.  There was rain about, though, and across the bay Brixham was veiled in a grey mist, its landmark lighthouse barely visible.  Fortunately for my afternoon, the storm gradually moved away, and the cloud over Paignton evaporated leaving blue sky and sunshine but with a strong blustery wind. 

Agapanthus seed heads

Yucca gloriosa with its lantern shaped flowers

I wandered about the gardens where the low sun was casting long shadows from the trees and shrubs, draining them of colour, leaving dark silhouettes.   The agapanthus had lost their blue flowers, replacing them with mop heads of chunky green seed capsules, like so many large lozenges.  A fuchsia hedge, covered in blossom last time I visited was now nearly devoid of flowers but, in compensation, yellowish-brown clumps of fungi grew beneath.  Some plants were still in bloom, though, and I was surprised to find several large clusters of creamy coloured lantern-shaped flowers with pinkish sepals, hanging like ornate chandeliers above thick clumps of spiky strap-shaped leaves.  These are yucca gloriosa, plants originating in the southern US although they seem to be very happy here.

Hoverfly (Eristalis tenax) on rosemary

Spread about the upper, sunnier parts of the garden, I also found several large banks of rosemary.  The plant grows prolifically here, covering long stretches of wall where it hangs like a pale blue curtain.  It begins to flower in late summer and continues through the winter providing important forage for insects; many of its locations here are also sheltered from the wind.   Despite recent heavy rain, the rosemary was covered in small, spiky, silvery-blue flowers and this is where I began to see pollinators.   A hoverfly, probably Eristalis tenax, the world’s most widespread hoverfly, was feeding and I managed a few photos despite its jumpiness.  Then I saw the first of several small bumblebees each with a furry, pale chestnut thorax and stripy abdomen.  They were nectaring from the rosemary, moving purposefully from flower to flower, taking away a dusting of pollen from the overarching stamens as they fed.  These were common carder bees (Bombus pascuorum) and as well as feeding they occasionally basked on the stones of the wall in the sunshine.  Sometimes, two or more were present on the same patch of rosemary and there was a little joshing between the insects.

I took as many photos as the carder bees would allow in the hope of being able to see their back legs as these are a key to establishing the gender. Where I was able to see the back legs, the insects were all males and Steven Falk kindly helped confirm my identification. These males must be late survivors from the second brood. The mated females will have settled down to hibernate and the males are left to live out their short lives.

I did see one smallish buff-tailed bumblebee (Bombus terrestris) collecting pollen, a worker which most likely comes from one of the winter active colonies that live in these gardens.  I was surprised to see so few but perhaps the weather had put them off or there were other flowers available in the many nearby private gardens.   The surviving male common carder bees have no nest to return to for shelter which may be why they were still foraging in this threateningly damp weather.

The storm over Broadsands and the change in the light

By now, another storm had bubbled up from the south west but this time it was closer and a fine grey haze hung over the beach and countryside at Broadsands just along from Goodrington.   The blustery wind chased the autumn leaves about and hurled a few large drops of rain at me, stinging my face.  The sea took on a sinister greenish blue tone and a kestrel appeared, hovering in the wind above the gardens, eventually landing on the steep cliff face.   I decided to get back to the car before the rain set in properly. 

The winter solstice – a day of sunshine – with flowers, butterflies and bumblebees

When the short day is brightest, with frost and fire,
The brief sun flames the ice, on pond and ditches,
In windless cold which is the heart’s heat,
Reflecting in a watery mirror
A glare that is blindness in the early afternoon.
(from Little Gidding, the last of TS Eliot’s Four Quartets)

Low midwinter sun behind pine trees at Roundham Head – silhouettes and shadows

 

We had a lot of grey, wet weather towards the end of last year, and very little sunshine. A few days before Christmas, however, the forecast predicted a bright, dry and relatively mild day, so I took the opportunity to get over to Roundham Head in Paignton to see what flowers and wildlife might be about. It’s a journey of about ten miles and that morning I took the bus, enjoying the long views across the surrounding countryside. Paignton is a seaside holiday resort but it looked distinctly “out of season” when I arrived, despite the sunshine and blue sky. A few people were walking along the promenade; they were well wrapped up even though it wasn’t a cold day. The little harbour was quiet; small boats bobbed on the water protected by the old stone walls and a gang of turnstones skittered like mice at the water’s edge. Molly Malones food shack was closed for the winter and the booths normally touting fishing excursions were empty.

I walked up suburban streets to get on to the northern side of Roundham Head, the flat-topped, cliff-lined, grassy promontory that protrudes into the waters of Torbay. A line of tall pine trees straddles the first part of the headland and the low sun rendered these as silhouettes casting long shadows across the grass. The path around the promontory follows the cliff edge with views to the sea below and a seal teased me by briefly raising its shiny black head above the water. Eventually I came to southern side of the Head and the gardens that were built in the 1930s partly to stabilise the cliffs. Steep zig zag paths track up and down between flower beds planted with exotic species that, between them, provide colour throughout the year. There are benches should you wish to rest or enjoy the views over Torbay and the shelter, the proximity of the sea and the south facing aspect of the gardens generate a mild microclimate.

The low midwinter sun over Goodrington Sands

 

It was the winter solstice that day, the shortest day in the northern hemisphere, the day when darkness begins to give way to light. From the southern edge of Roundham Head, above the gardens, I could see the sun hanging very low in the pale wintery-blue sky casting its light across the beach at Goodrington Sands creating a silvery mirror on the water. Even though this was midwinter, there were plenty of flowers around me in the gardens and the low sunshine created surprising effects. Its intense golden light gave a softness to the air and enhanced flower colours to an almost psychedelic extent. Banks of bergenia acquired a pink brightness worthy of late 1960s San Francisco and the scorpion vetch (Coronilla valentina) that flourishes all over the gardens glowed with a lemon-yellow light.

I paused by a clump of bergenia, enjoying the warmth of this sheltered spot. A small bumblebee, ovoid and furry with black, white and yellow stripes, soon appeared, moving among the bright pink flowers looking for food. Quickly tiring of the bergenia, it flew to one of the white funnel-shaped flowers in a large clump of shrubby bindweed (Convolvulus cneorum), burying its head in the base of the bloom where it stayed, drinking nectar. Based on size and appearance this was probably a buff-tailed bumblebee worker. A drone fly also took advantage of these flowers resting near the mass of golden yellow stamens. Soon after, I got a surprise when a butterfly landed briefly on the bergenia before flying off. It circled for a while before settling on a wall to bask in the sunshine showing me that it was a painted lady, with its characteristic wing coloration of orange/buff, black and white. An insistent buzz announced the arrival of a large bumblebee, black with orange/buff coloured bands. This was a queen buff-tailed bumblebee and she proceeded to feed from the bergenia. I had two more sightings of large furry queens on these pink flowers.

Another plant that flourishes here is rosemary and extensive curtains of the herb cascade from several borders, their slate blue flowers glinting in the sunshine like diamond chips. Rosemary is in flower here for several months across winter providing pollen and nectar for insects and I saw several buff-tailed bumblebee workers moving quickly about the flowers, their pollen baskets well loaded. They were very jumpy and flew off when I got too close. For a short time, they were joined by another queen carrying a small amount of grey pollen, also a basking, but rather worn, red admiral butterfly with its bright red and white patterns on a black background.

By mid-afternoon, cloud began to bubble up to the south, and eventually a slab of grey cloud obscured the sun. The temperature dropped noticeably, the wind got up and the bees went off to shelter, bringing observations to a close. I made my way back to the bus station pondering what I had seen.

It still surprises me to see butterflies in the winter. I have seen them here before in December and January but in my mind these brightly coloured insects signify summer. Although most red admirals are thought to migrate to the UK from North Africa and continental Europe, a few are thought to be resident now that mild winters are becoming more common. These residents can be seen flying and feeding on gentle winter days. The painted lady also migrates into the UK but is thought to be unable to survive our winters, so the one I encountered is unlikely to see our spring.

What about the bees, aren’t they supposed to be in hibernation at this time of year? Well yes, most bees are, but based on my observations of buff-tailed workers collecting pollen in December, there must be winter active colonies at Roundham Head. I first saw worker bumblebees here in January about five years ago and since then I have seen them at a similar time each year, so this is a well-established phenomenon. There are presumably queens in their nests laying eggs supported by these workers. These queens would have been produced in the previous October to mate with males at emergence. Last year I did see male buff-tails here in December so perhaps these were survivors of the late autumn emergence.

There is abundant evidence now from a variety of sources that colonies of buff-tailed bumblebees are active in the winter across the southern part of the UK. Two factors seem to be important: winter weather should not be too harsh and there should be plenty of flowers to support the colonies.

An amazing natural phenomenon goes unnoticed

After so many cool, damp and grey days, spring arrived in a rush in the third week of April. Temperatures soared by nearly ten degrees and the sun shone strongly from a virtually cloud-free sky, filling the air with an unexpected brightness, at least for a few days. The sudden change in the weather demanded that I get outside so I drove the short distance to the fishing port of Brixham, parking on the clifftop road on the eastern edge of the town. A steep stone stairway took me down the hillside past curious, deserted, rectangular buildings and wide sweeps of concrete enclosed by thick scrub echoing with birdsong. These are remnants of the Brixham Battery, built in 1940 to guard Torbay against a German invasion, now Grade 2 listed and an informal, unplanned nature reserve. Dandelions and cowslips were dotted about grassy areas and fleshy-leaved green alkanet with its grey-blue flowers provided a contrasting colour. The stairway continued downwards among trees until I was just above the sea where I joined the coast path.

This section of the coast path is enclosed by low scrub and, at this time of year, blackthorn dominates, its branches covered with a snow of small flowers, creating a curtain of white with occasional glimpses of the blue sea. In the bright sunshine, the delicate white petals were almost transparent below a confused mass of yellow-tipped stamens. Eventually, this enclosed path gave on to an open, grassy area roughly the size of a football pitch, overlooking the water of Torbay and backed by thick trees creating a sense of seclusion. Wooden benches positioned along the sea side were popular, occupied by people wearing sun hats and enjoying the spectacular view.  The full panorama of Torbay was spread out ahead like an enticing display in a travel brochure: the red cliffs, the white seafront buildings, the pine trees, the big wheel and, in the foreground, the Brixham breakwater with its white lighthouse. The sea was a bright, slightly greenish blue textured with patches of silvery sheen  and pleasure boats shuttled across the water to and from Torquay.  It was a holiday scene and felt almost Mediterranean.

Amongst all this human activity, no one seemed to be paying any attention to the many mini-volcanoes of crumbly soil partly concealed beneath the rough grass or to the many bees moving about the area just above the grass. Everywhere I looked there were bees flying about, backwards and forwards, swinging from side to side, as if they were trying to find something; a few were walking about on the red soil. There must have been thousands of bees, an amazing natural phenomenon and very exciting to watch. When I looked carefully, I saw that they were mostly black but with distinctive bands of pale hair. These are Ashy Mining Bees (Andrena cineraria), one of our more common solitary bees, and the soil volcanoes in the ground are their nests.

While I was taking in the scene, a couple arrived, both carrying plastic bags. He was in his sixties with long white hair roughly corralled into a pony tail. She was in her late fifties with copious dark hair. They threw down a blanket into the middle of the grassy area, stripped down to their underwear, cracked open some cans and proceeded to sunbathe. Like the other people, they didn’t notice the bees swirling about the grass around them and I wondered how they might react if they encountered the insects. Luckily for them, only the females of these kinds of mining bees possess a sting and they use it only when threatened.

I wanted to take some photos of the bees but, wishing to avoid any misunderstandings as I waved my camera about, I moved to the other end of the grassy area, passing a small turf-roofed building that used to contain the searchlight for the wartime Battery. I found an unoccupied bench, sat down, and providing I was still, the bees resumed their incessant movement around me. The bench turned out to be a front-row seat as, on several occasions, I saw one bee rush at another and the two struggled for a while on the ground. Two or three others tried to join in and it all got a bit confused and messy for a while. Eventually, however, only two were left coupled together, end to end. They stayed like this for a few minutes before separating and flying off. I presumed they were mating but it seemed rather sedate compared to the frantic copulatory behaviour of some solitary bees.

Photographing the flying bees is difficult, but for the short time they were occupied in mating they were relatively still, making it easier. My photographs showed that the honeybee-sized females have shiny black abdomens with a blue sheen in some lights. Two thick, furry bands of grey-white hair line the front and back of the thorax and the face is white-haired with black antennae. The slimmer and smaller males also have black abdomens but differ from the females in having white hairs on the sides of the thorax and thick tufts of white hair on the face. With their pale hairs and contrasting dark abdomens, Ashy Mining Bees are one of the most distinctive and beautiful species of mining bee in the UK.

Despite all this excitement on the ground, I kept an occasional watch on the sea and got quite excited when I saw a shiny black head emerge from the water. This was one of the local colony of grey seals swimming towards Fishcombe Cove. The water was so clear and calm that the seal’s huge body was clearly visible as it passed.

When I had finished, I walked back past the lush banks of three cornered leek that grow along the low cliff edge. I saw male Ashy Mining bees nectaring from the delicate white-belled flowers. Further on, I stopped to look at the blackthorn flowers. Here there were more Ashy Mining Bees foraging together with one very different bee with a shock of orange-brown hair on the thorax and a largely black abdomen tipped with orange-red hair. I later identified this as an Orange-tailed Mining Bee (Andrena haemorrhoa). With all this insect interest, there should be a good crop of sloes on the blackthorn here in the autumn.

A rare dose of autumn sunshine

Not far from the quaint, walled harbour at Paignton in South Devon lies Roundham Head, a rocky headland that protrudes nose-like in to the sea. The northern part of the Head is a grassy plateau and views from here across the vast sweep of Torbay can be spectacular. Today, rust-red cliffs glow and the steel-blue sea sparkles; even the slew of white buildings scarring the Torquay hills acquires some dignity in this bright, late autumn light.

On the southern edge of the headland are the Cliff Gardens and promenade, built in the 1930s to protect the crumbly rock against sea erosion. Paved paths zigzag up and down the steep slopes between flower beds and the gentle microclimate allows many exotic plants to flourish, providing a haven for wildlife. Dotted around the Gardens are the distinctive Torbay palms and the stiff breeze rattles their leaves like an avuncular uncle ruffling the hair of his favourite nephew.

I know it is autumn but as I walk up and down the zigzag paths it seems that the plants are less sure about the season. Yes, there are swathes of cobwebby old man’s beard, mature olive-green ivy berries with their rich brown caps and the agapanthus has exchanged mauve flowers for massive green seed heads. But there are also gaudy splashes of lemon yellow scorpion vetch, hanging curtains of rosemary with their sparkling blue flowers, clumps of shrubby bindweed covered with their yellow-throated white trumpets and dense sprays of pink bergenia.

With all these flowers about and a sunny, mild day, I expect to see wildlife. Eventually my patience is rewarded by the buzzy arrival of a huge furry bumblebee queen. Despite her size she moves deftly among the plants, systematically probing the rosemary and bergenia flowers. She appears to be in very good condition, and, in the sunshine, her golden yellow stripes glow and her tail is a warm tan colour, so she must be a buff tailed (B. terrestris). Later I see several worker bumblebees collecting pollen from the rosemary so there are active nests nearby, even in mid November. It doesn’t surprise me any longer to find these bumblebees at Roundham Head; I have seen them even in January and February and I am beginning to think that they are active throughout the year. What did surprise me was to find two yellow and black wasps mating on a fleshy green bergenia leaf. They start end to end, lying back on the leaf, but eventually the larger female mounts the male. When they are finished the fertilised queen will find somewhere to pass the winter, the male will die, his job done.

From the top of the Cliff Gardens there are good views down and across Goodrington Sands. This popular holiday beach is quiet today, its cafes and beach huts closed for the winter. The sea here is more battleship grey than steely blue but I also notice tinges of yellow and green where the underlying sand shows through shallow water. The strong offshore wind creates ripple patterns on the sea and lifts crests of fine spray from the incoming waves.

Once the tide falls back, dog walkers and their canine friends appear on the beach in the sunshine. The still-wet sand is a mirror to the sun and the dogs and walkers become dark silhouettes. Elsewhere on the beach, curious low piles of sand appear in apparently random patterns, the work of local bait diggers.

Ivy bee stories

For the past five weeks or so I have been watching the ivy bees (Colletes hederae) as they emerged from hibernation to mate and to build and equip their nests. South Devon is something of a hot spot for these insects and from my limited observations they can be seen all along the coast, at least wherever there is plentiful flowering ivy. They are by no means rare but I still get a thrill when I see them, especially if it’s in a new location (for me). There’s also something paradoxical about their frantic activity at a time of year when most of nature is shutting down.

Occasionally, something surprising happens when I am out observing, either because of people or because of the bees and here are two recent anecdotes.

Mansands and man’s hands

Last year I came across an impressive collection of ivy bee nests in the low cliffs at Mansands, an isolated beach near Brixham on the South Devon Coast (see featured image). There was plenty to see and the large number of nests was a surprise. The bees were mostly mated females so that the day I visited (October 3rd) might have been a bit late in the bees’ life cycle.

Part of the nest area in the crumbly cliffs

 

This year I decided to visit earlier with the hope of finding a mixture of males and females. We went to Mansands for the first time on September 15th; it was sunny and mild and not particularly windy but surprisingly I saw no ivy bees around the nest area. I did see a couple of ivy bees on a clump above the coastguard cottages but no others. There is quite a bit of ivy in the cliffs surrounding Mansands and in the approaching lanes but not much of it was in flower so perhaps I was too early.

I was keen to try again but life is rather busy at present and I didn’t have a chance until September 30th; that day we had an hour to spare and made a flying visit to Mansands. It was a sunny day and the temperature mild for the time of year (~16o). At the coast, there was a surprisingly strong and variable onshore wind which buffeted us as we walked down the steep stony path to the sea; on the way we saw plenty of ivy in flower. Under a clear blue sky, the sea was a uniform turquoise but the strong wind decorated its surface with white wavelets and created trains of foamy waves nearer the shore. The view was spectacular but given that I had come to see the ivy bees and Hazel to paint with watercolours, a little less wind might have been preferable.

A resting ivy bee, male I think

 

A pollen-loaded female ivy bee in the nest area

 

When we reached Mansands, I headed for the nest area, staggering slightly in the wind as I negotiated the stony beach. There were plenty of nest holes in the pinkish crumbly cliffs and a few, but not many, ivy bees about. It was so windy that they were finding it difficult to fly and difficult to land. Some of the bees were males patrolling hopefully, looking for females; from time to time they rested on the sand and grass. Females, their back legs dressed with yellow pollen-pantaloons, also arrived sporadically and, after resting, they made their way in to nest holes. The males paid no attention to these mated females.

Female ivy bee resting on my hand

 

As I watched, camera in right hand, a male approached the area and landed on one of the fingers of that hand. The camera was secured with a safety strap making it very difficult to manoeuvre and I failed completely to get a good shot of this trusting male bee. I was able to study this bee for some time by eye but in my experience a good photo reveals much more. Later, however, a female decided to land on my left hand. She seemed happy to stay there allowing me to get some rather nice photos from several angles.

This has never happened to me before and feels like uncharacteristic behaviour for solitary bees. They usually appear disturbed by my presence so, I assume, that on this windy day in their slightly dazed state they landed wherever they could.

Lots of wasps about today!

Should anyone watch me on one of my ivy bee investigations they will see someone gazing in a slightly bemused manner at a clump of ivy, marvelling at the behaviour of these small creatures. Many of these clumps are found along the South West Coast Path, many in the urban sections around Torbay so there are plenty of passers by. I don’t know what they think but for the most part these people ignore me.

Urban ivy at Hollicombe railway bridge

 

I recently discovered some particularly generous clumps of ivy cascading down one side of a railway bridge in Hollicombe. This is a Torbay district between Paignton and Torquay with a secluded cliff-enclosed beach. I have observed at Hollicombe several times and on the last two occasions, it was a very sunny, warm day and the ivy flower odour was particularly strong and cloying. I was transfixed by the energy expressed by the bees and other insects as they flew ceaselessly around the ivy flowers, and sometimes around my head! Even in this small area there must have been thousands of ivy bees. They were a mixed population of pollen-gathering females and nectaring males.

How many ivy bees can you spot?

 

On my most recent visit (October 2nd), I was standing by the ivy enjoying the bees and the warm sunshine when a man stopped to chat:

“Lots of wasps about today!” he began cheerily.

“They’re not wasps, they’re ivy bees” I tried to make my reply as helpful as possible.

“Horrible smell” he continued “what’s that plant with the smell?”

“It’s the ivy” I replied, again trying to be helpful.

“I hate it”, there was some anxiety in his voice, “it smells horrible”

“I find it sickly sweet but I don’t dislike it.” I replied, “Some people like the smell, some hate it. You know, like Marmite”

“What, you mean they use it to make Marmite?” he sounded shocked.

“No, no, no”, I couldn’t help sounding a little irritated, “what I meant was that people either like Marmite or they hate it and the same is true about the smell of ivy.”

“Oh,” he didn’t sound convinced.

“Would you like me to show you the ivy bees?” I offered.

“No thanks!” he said accelerating away down the path. He still thought they were wasps!

…………………..

There are many species of wasp in the UK but the species known and feared by many people are usually either the common wasp (Vespula vulgaris) or the germanic wasp (Vespula germanica). These are the familiar black and yellow striped insects which make such a negative impression on people. I remember in August this year, a hot midsummer’s day, when tea in an outdoor cafe was seriously disrupted by the creatures. I didn’t suffer any stings but I have in the past and it’s something you don’t forget. Many others have had similar experiences and given the passing resemblance between common wasps and ivy bees it’s possible that a really busy clump of ivy reminds people of these stinging insects.

The problem is compounded by the lack of knowledge among the general population about solitary bees. Most people don’t even know that solitary bees exist; the bees themselves are very reticent so that most humans rarely knowingly encounter them.

So, it’s no surprise that the man who accosted me mistook the ivy bees for wasps. Education is what is needed so I shall have to continue to offer to show the ivy bees to anyone who passes.

The Queen of Seaweeds – the story of Amelia Griffiths, an early 19th century pioneer of marine botany.

In 2010, the Royal Society compiled a list of the ten most influential female scientists in British History. One of the ten was Mary Anning (1799-1847) who from humble beginnings in Lyme Regis, Dorset came to be recognised as the “greatest fossil hunter ever known”. Her discoveries of long extinct, fossilised creatures in the cliffs around Lyme Regis were central to the development of new ideas about the history of the earth at the start of the 19th century. She became an expert in her field but did not get the recognition she deserved because science at the time was an exclusively male profession. Nowadays she is receiving this recognition and the fascination of her story has spawned biographies, novels and children’s books. The Lyme Regis Museum has well-developed plans to build an extension, to be called the Mary Anning Wing.

Mary Anning

I had thought that Anning was the only prominent West Country female scientist of her time until, walking along the coast path near Torquay recently, I paused to read an information board. This included a panel dedicated to the work of Amelia Griffiths (1768-1858) “who collected and preserved nearly 250 species of seaweed ……. one of the first women to be recognised for their contribution to science.” Never having heard of Griffiths, my interest was piqued, especially when I discovered that, in the 19th century, she was described as “facile Regina – the willingly acknowledged Queen of Algologists”. [Seaweeds are large multicellular marine algae.]

So who was Griffiths and what did she do?

Part of the information board that alerted me to Amelia Griffiths

Amelia Warren Rogers was born in Pilton, North Devon in 1768. In 1794 she married Rev. William Griffiths and the couple moved to Cornwall. Eight years later, her husband died suddenly under mysterious circumstances leaving his widow with five young children but not without money. Amelia Griffiths decided to leave Cornwall for Devon, living first at Ottery St Mary before settling in Torquay where she could best follow her favourite pursuit of studying seaweeds.

For much of her adult life she collected seaweeds avidly: in north Devon and Cornwall, in Dorset and along the East and South Devon coasts. When she began, identification of species was difficult as many had not been named or clearly described so Amelia devised her own names – “bottle brush”, “cobweb” etc. She helped male seaweed enthusiasts in producing scholarly studies on the larger and smaller seaweeds, generously giving her knowledge and donating samples. One such enthusiast was the leading botanist William Henry Harvey with whom she corresponded and who eventually became a close friend. Her reputation grew and in 1817, the Swedish botanist Carl Agardh named a genus of red seaweed Griffithsia in her honour.

Dried samples of seaweeds collected by Griffiths are held in several museums including Kew, Torquay and Exeter. Exeter’s Royal Albert Memorial Museum holds three slightly battered leather-bound volumes of her seaweeds which I recently had the privilege to see. Each sample is mounted on stiff white paper and annotated with the name and location in Griffiths’ neat handwriting. Many of the seaweeds still retain their bright colours despite being collected more than a century and a half ago.

Griffiths was often accompanied on her seaweed sorties by Mary Wyatt, formerly a servant in the Griffiths household but eventually the proprietor of a Torquay shop selling shells, polished madrepores and pressed plants. Harvey encouraged Mary Wyatt to sell books of pressed and named seaweeds to help identification. Supervised by Amelia, she produced the first two volumes of Algae Danmonienses (Seaweeds of Devon) by 1833. Each volume contained 50 species and cost 25 shillings or £1 if you subscribed to the series. The books sold well, being partly responsible for making seaweed collecting the must-do pastime at seaside resorts in early Victorian Britain. Followers of this seaweed craze were able to explore nature, improve their scientific knowledge and perhaps produce a memento of their seaside holiday.

Despite their extensive correspondence, Harvey and Amelia Griffiths did not meet until 1839 when he visited Torquay. At her urging, he wrote a hand-book of British Marine Algae later expanded to Phycologia Britannica, illustrating all known British Marine Algae. This great work required constant correspondence with Griffiths who despite being in her late 70s provided extensive knowledge of the plants in their natural state. Harvey held her in high regard and his hand-book contained the following dedication: “To Mrs Griffiths of Torquay, Devon, a lady whose long-continued researches have, more than those of any other observer in Britain, contributed to the present advanced state of marine botany….”

The more I investigated the story of Amelia Griffiths, the more I found similarities with Mary Anning. Both were systematic collectors, acquiring immense expertise in their fields and passing on samples to male scientists who furthered their own careers as a result. Both were strong women who pursued their interests whether or not these conformed to norms of society. Griffiths is known to have collected at Lyme Regis so perhaps she encountered Anning on the beach; it is an interesting thought. Anning is now better known, partly because her discoveries were much more significant for science and partly because of the well developed Mary Anning-industry in her home town.

Griffiths lived until nearly 90 maintaining her passion for seaweeds to the end. We must not forget that she began her systematic study of seaweeds in the early years of the 19th century, a time when women could not develop independent scientific careers. Despite this, she made a major contribution to marine botany and deserves to be more widely known.

I should like to thank Holly Morgenroth of the Royal Albert Memorial Museum, Exeter, who showed me Griffiths’ books of seaweeds and took the photographs.

The hills are alive with the sound of …… bees!

The fishing port of Brixham lies at the southern end of Torbay in South Devon. Last week, we walked along Brixham’s minor roads and quiet residential streets to reach a green lane leading away from the town and towards the coast path. The green lanes in Devon form a network of ancient tracks and here the green canopy, the high banks and the exposed bedrock kept us cool before we headed up hill over fields. As we climbed, we were rewarded with ever improving views over the entire panorama of Torbay. Here is a view towards Torquay with Brixham in the foreground.

The wide curve of the bay is certainly spectacular especially when the sun shines and if you imagine the bay without the scar of housing then you can see why visitors to Torbay in the late 18th century might have been reminded of Italy. One such visitor enthused: “It is not England but a bit of sunny Italy taken bodily from its rugged coast and placed here amid the green places and the pleasant pastoral lanes of beautiful Devon”. Even nowadays, the red valerian found in the summer all over this part of Devon manages to create some feeling of the Mediterranean although the modern, rather unsympathetic development of Torbay detracts.

Another picture below shows the fields above Brixham and if you look carefully at the surface of the field in the foreground, it appears to be covered with a white sheen. This is in fact white clover mixed with buttercups and other wild flowers.

We paused here to take in the view and to catch our breath on this warm day. It was very quiet but gradually we became aware of a low level hum. It took a while to realise what was causing this but when we looked more closely we could see that the field was full of bees, both honeybees and bumblebees; wherever we looked there were bees enjoying the clover. All our attempts to photograph the bees failed but here is a close-up of the clover.

White Clover

Emily Heath has recently talked about how honeybees and bumblebees like white clover on her AdventuresinBeeland Blog.

The noise we heard, let’s call it a “midsummer hum”, took me back to my first year at senior school when we read a book, Bevis by Richard Jeffries. This book, written in 1882, tells the story of two boys, Bevis and his friend Mark, and their adventures. These include mock battles with other children, rigging a boat and sailing to an island. At one point, the boys remark that the only sound they can hear is the “midsummer hum”. I can’t now imagine why this book was chosen for us to read; perhaps my English teacher thought it would capture the imagination of a class of eleven year old boys. The story also has clear parallels with the Swallows and Amazons books of Arthur Ransome, which were quite popular at the time. I remember not liking the book (Bevis) but for some reason, the idea of a “midsummer hum” has stayed with me all these years.
