The long-horned bee in Devon – and its endangered friend

South Devon coast looking towards Prawle Point
The south Devon coast looking towards Prawle Point (June 16th 2017)

 

It’s been a good summer. We’ve had some fine weather and I’ve been able to spend time on a beautiful part of the south Devon coast looking for the long-horned bee (Eucera longicornis).  It’s one of my favourite insects and one of our rarest bees and there is a strong colony on the coast between Prawle Point and Start Point where low, soft-rock cliffs meander around headlands, in and out of rocky coves and along seaweed-covered beaches.  I visited this area several times between May and July but my most interesting day was on June 23rd, just after the summer solstice.

It was breezy and warm but partly cloudy when I arrived at the coast.  The sea was a uniform grey-blue although now and then the sun broke through the cloud, creating shimmering areas of white water. I started by following the coast path eastwards along the cliff top from Prawle Point.  The sea-side of the path was fringed with scrub and rough grass along the cliff edge whereas the landward side was fenced and mostly used for arable farming.  Many kinds of wild flower grew along both sides of the path including a few generous clumps of purple tufted vetch scrambling through the scrub. After about a mile of easy walking, the enclosed path reached a gate giving on to a broad, open area, not farmed for some years, as far as I know.

I was completely unprepared for the view that greeted me after I closed the gate.  Here was a meadow where thousands of the small, dandelion-like flowers of cat’s ear moved with the breezes to create a mobile yellow canopy above the grass.  Lower down were many tiny yellow globes of hop trefoil and bright pink semi-circles of common vetch.  This is a paradise for insects and I saw many red-tailed bumblebee workers moving purposefully about the chrome-yellow flower heads.

But that wasn’t all: the area along the cliff edge was a kaleidoscope of purples, yellows and pinks, mostly flowering legumes such as bush, kidney and tufted vetches, bird’s foot trefoil and meadow vetchling, restharrow and narrow-leaved everlasting pea.   The number and variety of flowers was greater than I can remember from previous years, perhaps the warm spring had suited the legumes.

The range of flowers, especially the legumes is ideal for the long-horned bee.  I had seen one or two males back along the enclosed path and now I saw several more, also nectaring on the curving, purple, tubular florets of tufted vetch.   There is something other-worldly, almost primeval about these insects with their yellow mask-like face, orange-chestnut hair (in fresh insects) and their impressively long antennae, resembling stiff black bootlaces and about the same length as rest of their bodies.  They are particularly striking in flight, antennae held so that the bee can negotiate whatever obstacle it meets;  controlling those antennae must involve some impressive micro-engineering.   There were also females about feeding on lemon yellow pea-like flowers of meadow vetchling.  Chunkier than the males, they have shorter antennae and, on their back legs, generous pollen brushes resembling golden harem pants.

I scrambled down a rough track to the main Eucera nest area, a section of reddish, soft-rock cliff, pock-marked with hundreds of pencil-sized holes.  Behind me the sea soughed rhythmically on nearby rocks and an oystercatcher sang its plangent song. Female Eucera arrived at the nest site bringing pollen and nectar to provision their nests but they were not alone and I saw several other bee species that seemed to be using the nest area.

One species I had hoped to see was the very rare Nomada, and I had nearly given up hope when the bee suddenly appeared; I was so surprised, I nearly fell backwards off the rocks.  Like others of its kind, it is wasp-like, with a yellow and black-banded abdomen and orange legs and antennae. It was the pattern of the bands, six yellow bands on a black body that told me that this was Nomada sexfasciata, the six-banded nomad bee, one of Britain’s rarest bees.  This site on the south Devon coast is the only place where it is found in the UK; it is nationally endangered so it was very exciting to see it.

It moved about the nest area furtively as if trying not to be noticed and after looking in to a few of the holes it moved on. Later that day I had more sightings of the Nomada; whether it was the same bee or several I cannot say.  As a nomad, the bee has no nest of its own but lays its eggs in the nest of another bee, in this case the long-horned bee.  The Nomada eggs develop into larvae and take over the nest, killing the host larvae and eating their pollen store.  It depends for its survival on a strong Eucera colony and this one in south Devon is one of the largest in the UK.

Long-horned bees and their Nomada used to be found widely across the southern part of Britain in the early 20th century.  They favour a range of habitats such as coastal soft rock cliffs, hay meadows and woodland rides for nest sites and require unimproved flowery grassland for feeding, being especially dependent on flowering legumes for their pollen sources.  With agricultural intensification leading to a loss of habitat, especially flowers, these bees have been squeezed out and are now confined to a very few sites.

It’s not difficult to see how they could be supported.  At the south Devon site, all that is required is to ensure a consistent source of flowering legumes along the coast, the soft rock cliffs already provide the nest sites.    I recently met Catherine Mitson who is working with Buglife on a project to support the south Devon colony of Eucera longicornis and Nomada sexfasciata  by increasing the number of flowers.  Catherine is very enthusiastic and I have great hopes now for the survival of both the long-horned bee and its nomad.

Flower-rich hay meadows on the Golden Cap Estate in west Dorset

For hundreds of years, colourful, flower-rich hay meadows were a defining feature of the British countryside and its way of life.  The 20th century saw a tidal wave of agricultural intensification sweep through the countryside accompanied by increased use of herbicides and pesticides.  The flower-rich hay meadows were a major casualty of this change and 97% of those present in the 1930s disappeared.  Dorset still has some traditionally managed meadows and, at the beginning of May, I went to Westhay Farm below Stonebarrow Hill on the Golden Cap Estate in west Dorset where the National Trust maintains this age-old agricultural system.

Westhay Farm Meadows
Westhay Farm hidden away in the Golden Cap Estate

 

I followed the narrow lane as it rose steeply between houses and through woodland along the course of the old ridgeway road towards Stonebarrow Hill.  Red campion, cow parsley, stitchwort and bluebells grew thickly along the grassy verges and bright sunlight filtered through the trees giving an unexpected transparency to overhanging leaves.  Emerging from the tree cover, the lane levelled out and, to the right, the land fell away steeply in a patchwork of fields, hedges and trees towards a calm sea with just a light surface stippling.

Hidden away in this landscape is Westhay Farm, with its long, mellow-stone farmhouse set in a lush garden and surrounded by hay meadows.  At this time of year, the meadows are richly carpeted with knee-high, yellow buttercups and tall, rough grass with prominent flaky seed heads.  When breezes meander across the valley towards the meadows, the grasses and flowers respond, moving together in waves, like the swell on the sea below.

Partly concealed within the rough grass were tight clusters of lemon yellow flowers above thick reddish green stems.  This is yellow rattle, a traditional meadowland plant, with its tubular flowers open at one end where the upper petal widens to a smooth, cowl-like structure above protruding purple stamens.   A black and yellow-striped bumblebee systematically visited each flower pushing the two petals apart so that its long tongue could reach the nectar at the base.   When it left with its sugary reward it also took away a dusting of pollen from the overhanging stamens to pass on to the next flower.

Yellow rattle is a hemi-parasite; although it can use sunlight energy itself by the process of photosynthesis, it does better when it also establishes physical connections to the roots of other plants in the meadow such as grasses.  The yellow rattle siphons off nutrients from the grasses, suppressing their vigour and creating space for other plants to thrive.  This is very important for establishing a meadow with a wide range of species.

Some of the meadows contained drifts of the glittering, brightly coloured flowers of green-winged orchids, standing defiantly in the grass on thick green stems.  Many of the orchids were purple, some were magenta, some violet and a few were white or pink, lending a mosaic of contrasting colour to the meadow.  Each flower was composed of several florets arranged around the stem like jewels on a bracelet.  The most visible and exquisite part of each orchid floret was the broad, apron-like, lower petal with its central white stripe contained within a coloured halo.  This white region was decorated with a pattern of eight or more irregular darker spots, the pattern unique to each floret and perhaps decoded by visiting pollinators.  Green-winged orchids are a speciality of these meadows and their name refers to the green-veined sepals that protect each developing floret, now thrown back like wings.

The Westhay meadows were a fine sight in early May with their colourful flowers and seemingly unfettered growth.  As the seasons progress, the meadows will mature, the yellow rattle and orchids will disappear, their place taken by other flowers.  By July the grasses will be dry and cheerful newcomers such as purple knapweed and buttery-yellow bird’s foot trefoil will bring their colours to the mosaic.  In late July, the hay will be cut, this joyous, abundant growth converted into winter animal feed.

Flower-rich hay meadows such as these were a feature of the British countryside in the spring and summer for centuries.  Cultivation followed the rhythm of the seasons.  Grasses and flowers grew in the warmth and wet of spring and early summer and a unique species-rich environment developed.   Hay was cut in late summer and removed for winter animal feed, after the flowers had set seed.  Animals grazed the fields in autumn taking advantage of the late-summer grass growth, the aftermath. No chemicals were used and the only fertiliser came from the autumn-grazing animals. The following spring, plants grew, seeds germinated and the cycle began again.  This was a carefully managed land cultivation system, in tune with the seasons and their weather.

Haymaking was an important part of the rural calendar, a natural part of each year’s cycle, celebrated in literature and art.  Here is part of William Barnes’ poem Haymeaken depicting a 19th century rural Dorset scene:

‘Tis merry ov a zummer’s day,

Where vo’k be out a-meaken hay ;

Where men an’ women, in a string,

Do ted or turn the grass, an’ zing,

Wi’ cheemen vaices, merry zongs,

A-tossen o’ their sheenen prongs

Wi’ earms a-zwangen left an’ right,

In colour’d gowns an’ shirtsleeves white

All this was set to change in the 20th century.  Fears for food security during the two world wars led to agricultural intensification and an increased dependence on artificial fertilisers.  Flower-rich hay meadows all but disappeared, a way of life evaporated and the look of the countryside changed.

It wasn’t just the look that changed.  Adoption of new methods coupled with increased use of herbicides and pesticides significantly affected wildlife in the countryside.  Loss of farmland birds and pollinating insects such as bees, butterflies, wasps, moths, flies and beetles has been severe.

Bees in a landscape

I’ve always loved visiting galleries, discovering what an artist has created, but in the first week of May, the tables were turned.  For the first time, I was on the other side presenting a joint exhibition with my artist wife, Hazel.   We called the exhibition, “Bees in a Landscape”, and it was based around Hazel’s semi-abstract paintings of memorable views from the South West of the UK depicting the local landscape in all its glories.  Alongside the paintings, I showed photographs of some of the bees I have encountered in these same locations.   We hoped that the exhibition would raise awareness of the variety, beauty and importance of these beneficial insects as well as showing how we can all support them.

It was more than a year and a half ago that we agreed to put on the exhibition and throughout 2016 I photographed bees and Hazel worked hard on her paintings.  I didn’t spend hours looking for rare examples, I just photographed the bees that I saw, often in local gardens or when Hazel and I were out walking together by the coast.  It has certainly made me look more carefully at insects and flowers when we go out.

As the week of the exhibition approached there were many things to arrange: had we done enough publicity, did we have enough wine for the Private View, had we sent out all the invitations, would enough people come? Fortunately Hazel has a lot of experience in putting on exhibitions.  When we spoke to people in the run up to the exhibition, we detected a genuine interest in the topic of bees and the landscape which was very reassuring.

Hanging the Exhibition finally finished!

The most stressful time was “hanging” the exhibition.  All the paintings and photos were ready but we couldn’t get in to the gallery until 1730, the evening before the exhibition opened on the Sunday.  There were a few distractions, and it took longer than we expected to decide how to place the work around the gallery and to mount it on the walls, and we had to come back on Sunday morning to complete the job.  In the end, we finished with just enough time to nip home to change and be back to welcome guests for the Private View.

The Private View is one of those special artists’ events that goes with an exhibition.   It’s a chance to invite friends, other artists, and people with a special interest to share a glass of wine before the exhibition is open to the public.  Many people came and everyone seemed genuinely interested and impressed by the work.  We were also very fortunate that, during the Private View, Totnes women’s choir Viva, sang for us creating a magical atmosphere with their beautiful harmonies.  Led by Roz Walker, and dressed in yellow and black, they sang songs about bees based on poems by Rudyard Kipling, Carol Ann Duffy, Vita Sackville-West and one based on the Finnish epic poem the Kalevala.   We were so grateful that they gave their time to come and sing for us.

The Exhibition was open that afternoon and then daily until the following Saturday.  Hazel and I split the stewarding duties which meant we each did a morning or an afternoon in the gallery.  Totnes is a busy place and the gallery is in the centre of town so up to 100 people came in each day.  We both had many interesting and unexpected conversations with visitors and I was very surprised at the warmth and interest shown by people who came to look at the pictures, both landscapes and bees.  On many occasions, I heard the comment:  ” I didn’t realise how many kinds of bee there were in this country and how beautiful they are!”  Hazel found that her paintings evoked memories for visitors: of childhood picnics, happy holidays and even a honeymoon.  The greetings cards featuring images from the Exhibition were also very popular.

On the Tuesday, I took a small group on a Bee Tour of the public gardens dotted around the centre of Totnes.  It wasn’t a very sunny day but we had wide-ranging discussions and were able to see some interesting bees foraging on large patches of comfrey and cerinthe including female Hairy-footed flower bees, early and tree bumblebee workers and a garden bumblebee queen.

Soundart
My debut on Soundart Radio

Our exhibition was featured on Soundart, a local community radio station.  One of the presenters interviewed Hazel in the gallery and I went to the studio to talk about bees.  This was an interesting experience, if not altogether satisfactory.  After Hazel’s interview had been played, the presenters asked me about the exhibition and about bees which was fine.  When we got on to neonicotinoids, however, the discussion was hijacked by one presenter.  He challenged the possibility of obtaining “evidence” in scientific investigations of complex systems like bees and after his intervention, the bee discussion petered out which was a shame as there were many other aspects we could have covered.

Hazel and I were extremely pleased with the exhibition.  Many people came to look and we had some fascinating conversations.  Several people made special journeys to visit and talk to us.  People went away knowing more about bees.  What more could you we have asked for!?

Fragrant flower or invasive thug?

We’d been walking for twenty minutes or so with plenty to see: a wooded garden with a drift of early snowdrops scattered across the grass like confetti, the winter sunshine percolating through the trees creating mosaics of light and shade, running water a constant companion. Then suddenly, something new captured my attention but I couldn’t immediately identify what it was. You know how it is when you hear a fragment of a well-known piece of music but can’t place it; only this wasn’t music. Gradually, though, I became conscious of a low-level odour permeating the air by the path. I am sure there had been other smells as we walked, such as rotting leaves and wet mud, but this was entirely unexpected: a sweet, fragrant odour that stopped me in my tracks.

It was the day after Christmas and we decided to walk the riverside path linking the village of Uplyme in the far east of Devon to the seaside town of Lyme Regis just across the border in Dorset. This was the most rural section of the walk. One side of the path was bordered by skeletal trees and a damp, woodland bank. Hart’s tongue ferns grew prolifically, their leaves spilling out across the soil, octopus-like. On the other side of the path, the ground fell away steeply to the river Lym.

But the ferns did not have it all their own way and a small section of the bank was occupied instead by heart-shaped, bright green, fleshy leaves. Floating above the leaves, on thick stems, were the flowers, daisy-like brushes of pale petals gathered together and swept upwards. Each slightly hairy stem carried several of these chunky flower heads. This was winter heliotrope (Petasites fragrans).

I bent down to smell the flowers and was greeted by a sweet, cloying fragrance that spoke to me of almonds and resurrected distant memories of amaretto liqueur; this was the source of my arresting sensory experience. Although I smelt almonds, it turns out that there is some disagreement about the exact odour of winter heliotrope. Perhaps it is the complexity of the smell; there was indeed an additional hard edge to the `fragrance that I couldn’t place, and some say the flowers smell of almonds, others vanilla, some even licorice and I began to doubt my response.

Back home, I looked for another patch of the plant to test my nose. Finding the plant wasn’t a problem; there is a lot of winter heliotrope about at present in south Devon. Much of it, however, grows by busy roads and it took me a while to find some that I could smell safely. I finally struck lucky by the coast path above the beach at South Milton Sands. Here I found drifts of winter heliotrope, some in shade and some in sunshine on the cliff top. The flower heads trembled in the breeze and the late afternoon sun highlighted the delicate colours of the flowers, some pale lilac, others tinged dark pink. Sometimes, the sea breeze carried traces of that low level woodland odour.

But what was the smell of the flowers in this seaside location? I took first sniff and smelt almonds again so my earlier response had been correct. Next Hazel tried without knowing my experience and she said lilac. It would be interesting to know what others sense when they smell winter heliotrope.

Many people, however, have an entirely different reaction to winter heliotrope, they hate it! They regard the plant as an introduced, invasive thug, taking over landscapes and eliminating native plants like a triffid destroying everything in its path. I share these concerns, but I have to admit to having a soft spot for winter heliotrope. It brightens up the sparse winter landscape and provides welcome forage for early insects. South Devon, with its mild climate, supports colonies of winter bumblebees and they need forage throughout the season. Winter heliotrope provides some of that food and this morning I watched winter bumblebees foraging on the flowers above the sea in Torquay.

Liquid Energy – ivy bees by the sea in South Devon

Here is an account of a visit I made to Paignton about eight weeks ago, seaching for ivy bees.

Goodrington Sands
Goodrington Sands viewed from Roundham Head

 

Ice cream and chips, not together of course, but that’s what people are eating. The sun is shining, the sea an intense blue, the air gently warm and sun loungers have been dragged unexpectedly out of pastel-coloured beach huts. Couples stroll along the promenade arm in arm and one or two children shriek with delight as they run in and out of the waves washing over the long sandy beach. This is Goodrington Sands near Paignton in south Devon and it’s the end of September.

At one end of the beach, the ground rises steeply to Roundham Head, a cliff-lined, grass-topped promontory that interrupts the otherwise smooth sweep of Torbay. The south-facing side of the headland is home to the Cliff Gardens with its terraced flower beds, zigzag paths and mild microclimate supporting many tender sub-tropical plants. A colony of winter bumblebees also flourishes here, nurtured by the almost year round supply of pollen and nectar.

The flat, grassy surface of the promontory eventually gives way to residential streets but before suburbia takes over completely, there is a transitional region, a mosaic of green rectangular spaces and tall, red-brick walls. Nowadays, the area is popular with dog walkers but, in one wall, there is an intriguing, curved-top gateway, hinting at older usages. These walls, now mostly covered with ivy, are the remnants of the kitchen gardens of a nearby Victorian villa.

About a year ago, I discovered these old walls covered in full-flowering ivy with many ivy bees taking advantage of their preferred food. The ivy bee (Colletes hederae) is the last solitary bee to emerge each year and is very distinctive with its yellow and black-striped abdomen and chestnut-haired thorax. I looked for the nest area but, although I found a few small nest aggregations, I was unable to find anywhere large enough to support the number of bees I had seen.

Today, I park in a street bordering the old kitchen garden. Ivy cascades over the wall by the car, its many pale green flower heads scenting the air with their sickly-sweet smell. Insects move about the ivy constantly, flying to and fro, ignoring me to the extent that we sometimes collide. I see hoverflies, wasps, one or two bumblebees and honey bees, and hundreds of ivy bees. The male ivy bees fly about edgily, sometimes stopping to feed, sometimes pausing on a leaf to preen and rest. The females, noticeably larger than the males, carry chunks of chrome yellow pollen on their back legs and abdominal hairs but continue feeding. Sometimes a hopeful male disturbs them, attempting to mate, but they show no interest in their new suitors. Movement is constant, there is an insistent low buzz and this liquid energy steps up in the sunshine. The same liquid energy abounds wherever the ivy is in flower on these old walls. There is a lot of ivy here and that means many ivy bees.

But where are the nests? Last year I found one small nest area in some exposed red soil along the cliff-side path descending from Roundham Head to Goodrington so that’s where I begin today. Sure enough there are still holes in the cliff face together with crumbly soil suggesting active nests. Around these holes there are hundreds of ivy bee males performing what my friend Susan Taylor has christened the “sun dance”. They fly about incessantly, swinging from side to side, occasionally stopping to look into one of the holes but emerging unsuccessfully. It’s an impressive sight along a two metre stretch but what is lacking are any females and anyway it doesn’t feel like a big enough area to account for all the bees on the ivy so I decide to walk down to Goodrington to look at the sea.

As I stand by the beach, I see someone walking down another steep path from Roundham Head. I hadn’t noticed this paved path before: it runs parallel to the cliff-side path but about three metres inland and is partly hidden behind a low hedge. I decide to take a look. The path is bordered on one side by a low bank covered in short, rough grass and hundreds of ivy bee males fly about, skimming the surface, “sun dancing”. When I get closer, I see that the red soil in the bank is peppered with many holes and crumbly soil is spilling out showing that the bank contains active nests.

The males here seem particularly edgy, they constantly investigate the burrows, presumably looking for females and sometimes they even try to mate with one another, not a clever move. On several occasions I notice the males suddenly congregating to form a rough ball. Other males soon join the melee rather like rugby players in a ruck. Somewhere in the middle there must be a female who has just emerged from one of the burrows. The males are trying frantically to mate with her but only one will be successful and I see one copulating couple fly off together, still attached.

There is also a slow but steady stream of females returning to the nest area loaded with yellow pollen. They have come to deposit food in their burrow for their larvae, but finding their nest looks a bit hit and miss. Some approach the area and fly around for a short time before landing and making their way on foot. Others seem to crash land and then pull themselves together after a short rest. The males show no interest in these already-mated females.

The aggregation covers an area about ten metres by half a metre and there must be hundreds of nests. This is a large, very active, nest site and looks big enough to support a huge number of ivy bees. I can’t say whether there are other nest aggregations in the area but this one goes some way to explaining the large number of ivy bees seen at Roundham Head.

I am completely absorbed watching these creatures go about their lives; it’s like being allowed through a door into another world. But then I look up and see, no more than 20 metres below me, an ice cream kiosk with people enjoying their Devon Farmhouse ice cream. Dogs dash along the hard sand splashing in the water. A steam train struggles up the bank hauling vintage chocolate and cream coaches towards Kingswear.

An autumn sunshine walk in South Devon – Salcombe to Gara Rock

East Portlemouth Ferry
The ferry arrives at East Portlemouth from Salcombe

 

Steep steps descend from a narrow passageway off Salcombe’s Fore Street.   At water level there is a stone jetty, the Ferry Pier, and above and to the right the Ferry Inn enjoys almost perfect views across the estuary.   A clinker-built motor boat, with the skipper standing up, is already making its way across the water to pick up the few waiting passengers.  Once we are all safely on board, he backs out and turns before heading across the estuary to East Portlemouth; it’s a calm day so this is an easy crossing.   The view from the boat always impresses me, low in the water, a cormorant’s perspective.  Looking towards the mouth of the estuary, the sea is a dark blue but, in the light breeze, ripples caught in the low sunshine cast a dancing light across the water.

The journey takes only a few minutes but it’s transformative.   Salcombe is all cafes and posh clothing shops but across the water we find peaceful long beaches with fine sand.  The tide is very low so we follow the strandline, leaving a record of our footsteps in the soft sand.  Beachside houses cast long shadows in the low sunshine but, where the sun reaches the beach, it creates pale blues and greens in the seawater, shallow over golden sand, and I imagine the Mediterranean.

Eventually, we reach Mill Bay, a football pitch-sized expanse of undulating, pale sand stretching from the sea to the coast road.  Very popular for family holidays in summer, today it is all but deserted.  On one side of the beach, the low tide has exposed a long, green, seaweed-covered slipway with prominent metal rails and stone teeth.  This was built in 1943 by the US navy to support landing craft during the Normandy landings.  It’s hard to imagine the beaches and the estuary filled with ships awaiting the assault on occupied France.

The rear of the beach is fringed with sand dunes bound together with scrubby grass.  One exposed vertical face is peppered with holes, burrows for insects, and several black and yellow striped wasps are moving about the nest area in a proprietorial manner.  Longer and sleeker than the better known common wasp, these are field digger wasps, solitary insects that dig tunnels in the sand and provision them with dead flies as food for their larvae.  A large buff-tailed bumblebee queen is scrabbling in the sand wall as if she is trying to burrow.  She looks in good condition but behaves as if something is wrong.

The path leaves the beach to head gently upwards through coastal woodland in the direction of the estuary mouth.  The autumn leaf-strewn track meanders through the woods with tantalising views of beaches below.  In today’s light, the colours of the sand and water glimpsed through the trees look more southern European than south Devon.  We emerge from woodland cover into brilliant sunshine and spectacular but slightly hazy views across the mouth of the estuary to the vast green headland of Bolt Head and the sandy beach at South Sands with its boutique hotels.  A red, yellow and blue boat passes by purposefully; it may look like a toy, but it is the Ferry that links South Sands with Salcombe town.

The path turns gradually eastwards seemingly cut into the hillside so that we walk with the land falling away to the sea below us and, on the landward side, rising steeply to rocky outcrops.  There is much bracken in evidence, already showing the effects of autumn; bright sparks of yellow gorse shoot upwards.  We pass a single spike of mullein, a few yellow toadflax and clumps of sheep’s bit with their unruly mops of blue petals.  Several stonechats entertain us, fluttering up and down, tail flicking, chatting.

The sea is calm today. From this vantage point, it is a deep blue but where it meets the rocky coastline, the surface shatters into bright fragments in the sunshine.  I scan the coastal waters for seals but get a surprise when I see what looks like a person standing on a rock just above the sea.  A closer look reveals a large cormorant, sunning itself.   Further away, sailing boats take advantage of the good weather and a fishing boat moors close enough for us to read its name through our binoculars.

Eventually, ahead of us we see a curious, white-painted, cylindrical hut, topped with a thatched roof and perched high above the path upon one of the rocky outcrops.  Far below the hut is a secluded stretch of sandy beach and in the distance lies another headland, Gammon Head.  The thatched hut is the former coastguard lookout at Gara Rock and we leave the coast path to head up to investigate.   Behind the lookout there is a new resort/hotel/apartment complex with people sitting in the sunshine enjoying a drink.  A row of coastguard cottages was built here in the 19th century and converted into a popular hotel early in the 20th century.  Laurence Olivier, John Betjeman and Margaret Rutherford are said to have stayed here, not necessarily at the same time.  The old building was knocked down in the last ten years and rebuilt as the new complex.

The old coastguard lookout has glorious views across the sea and coast and it is surrounded by huge banks of ivy.  Much of the ivy is in full flower, filling the air with its distinctive sickly-sweet smell.  Perhaps it is something to do with the light today but the flower heads on these clumps of ivy appear as almost perfect globes.  Multiple pale green lollipops extend from the centre of each flower head in perfect symmetry, like pins in a pin cushion.  Each lollipop is decorated with a frieze of pale yellow-headed stamens, creating, from a distance, a sunny halo around the green globe.  The ivy flowers attract many insects including more field digger wasps but it is the ivy bees that I am looking for and I am not disappointed.  Many of the elegant yellow and black striped-females move quickly about the flowers together with a few hopeful males.  The females are carrying large amounts of bright yellow pollen but still feeding.

We drag ourselves away from this extraordinary spot and head back down the inland valley to Mill Bay following an ancient, slightly sunken green lane with farmland either side.  This is a green tunnel with muted light, formed by overhanging trees including a long stretch of very old lime trees with dark, gnarled bark and multiple branching trunks.  When we reach Mill Bay, we take the coast road back to the jetty.  Many of the houses here are closed up; more than 40% of the houses in the Salcombe area are second homes.  The chimney of one of these homes is swarming with bees, probably honeybees.  The owner will be in for a shock when they next visit!

Love bugs and other surprises at Bantham Beach in south Devon

Last weekend we took advantage of the mild weather and went to Bantham Beach for a picnic and a walk. It being Sunday, we weren’t the only ones with this idea and, by the time we arrived, a flotilla of windbreaks had appeared on the beach, sails flapping in the breeze and barbeque smoke drifting aimlessly. Bathing didn’t seem to be high on the agenda; the tide was very low and the water still rather cool, so there was much paternal sandcastle building and a group of young men worked off their testosterone in a game of head-the-football. Despite this, there was plenty of space and the situation and the views were glorious.

After our picnic, Hazel wanted to do some sketching so Elizabeth and I walked on the cliff path where there are good views across the Avon estuary to Burgh Island and its art deco, icing sugar, hotel. Thrift was beginning to form its pink, cliff-top drifts and yellow kidney vetch was showing well. A couple of rock pipits skittered skilfully around the cliffs.

As we walked, I watched out for interesting insects and was well rewarded. Several small solitary bees with black abdomens and pale stripes bathed in dandelion petals, nectaring I suppose. The BWARS experts told me that these were Andrena males but from my pictures we couldn’t identify the species.

Later on we saw two black St Mark’s Flies “loved up” (I owe this expression to Emma Sarah Tennant). It is, in fact, a very appropriate expression as these flies are also called “love bugs” because of their ability to copulate in mid air.

On a rising part of the cliff path we found a long section of hard, grass-free soil with many small holes. We also found some of the occupants, one dead and one alive. These are Polymorphic Sweat Bees (Halictus rubicundus); the females have a pale- striped, black abdomen and their hind legs are coated in yellow/orange hairs.

We had agreed to meet Hazel near the Gastrobus for a drink. Elizabeth and I arrived a bit early but eventually I saw Hazel coming along the sandy path across the dunes from the beach. Suddenly she shouted: “Come quickly, get your camera, it’s an adder”. I did as she said and fumbled my camera out of its case. Sure enough slithering across the path was a very fine adder that disappeared in to the rough grass on the other side of the path leaving only swirly patterns on the sand. As I was taking the photos I did my best to look at the snake; the zigzag patterns and the colours did make an impression but the photos tell the story better.

There are many signs dotted around the dunes at Bantham warning about ”Adders”. Now we know why!
