Bumbling Around for Butterflies

My quest to see all 58 species of butterflies in the UK seems to have stalled somewhat, but I’ve still had a really good summer for butterflies this year, both at home and out and about. Best and most surprising of all was getting to see some Large Copper butterflies less than 40 miles from home. Given that the Large Copper is actually considered extinct in the UK and has been so since the 1850s, it’s not a butterfly I ever imagined seeing. But some bright spark had chosen to release them (possibly as caterpillars) at the brilliantly named Bumble Hole Nature Reserve in Dudley.

I resisted for at least 10 days after the first photos started appearing on Facebook, but finally gave in to temptation and headed north to Dudley. With some help from a kind lady in the visitor centre, I headed to the butterfly hotspot – obvious when I was in the right area due to the dozen or so other butterfly twitchers. I was still fumbling to get my camera out, when the first Large Copper appeared.

The males are pretty much all bright orange on the upper surface of the wings, with a pale blue dotted with black spots underneath.

The females have more brown markings, stripes and spots on the upper side, but are similar underneath.

It was a baking hot day and my plan originally had been to stay out just long enough to see the butterflies and then head back to the safety of the air-con in the car! But the butterflies were so stunning and more numerous than I had expected, so I kept getting side-tracked by another one each time I started to head back. My final reward for this heroic effort (an hour in baking sun for a dumpy middle-aged woman is I’m sure the equivalent of an iron-man challenge for other people) was to spot this female laying eggs. Well worth the sunburn.

It was a magical thing to see these butterflies in the UK, but sadly it is probably not all good news. As their release seems to have been unsanctioned, the chances of the butterflies surviving at this site are apparently small. Although they were clearly mating and obviously laying eggs, will the eggs and/or caterpillars be able to make it through to next summer? It would be wonderful if they did manage to establish a colony here, but many people are doubtful that the conditions at Bumble Hole will be right for them.

For comparison here’s a Small Copper taken at Croome Park this week.

In other news the local Facebook groups were buzzing with the news that there were multiple Clouded Yellow butterflies down in the fields near Grafton Wood. As usual I could resist anything but temptation, so headed down there to see for myself. First attempt was a complete wash-out as I picked the only cold cloudy day in August, but second attempt was more productive. Together with a very nice couple I met down there, I watched in frustration as the bright yellow flashes of several Clouded Yellows dashed about the centre of the fields. Not wanting to trample across the farmer’s fields we could only watch and hope they would eventually come to the margins. Eventually a few did, but they were so flighty that all I managed was these blurry yellow blobs for photos. But at least I saw them.

Slightly more obliging were some Common Blue, Small Heath and Brown Argus.

At home I did a couple of Big Butterfly Counts earlier this month. The garden generally has been busier than recent years for butterflies, but as usual most of them declined to put in an appearance during the 15 minute counts. But so far this year I’ve seen Red Admiral, Peacock, Small Tortoiseshell, Comma, Painted Lady, Large White, Small White, Holly Blue, Gatekeeper, Meadow Brown, Speckled Wood and Ringlet butterflies in the garden. But best of all was a Silver-washed Fritillary which graced my buddleia and bramble-strewn garden with its presence over several days.

So that’s a round-up of this summer’s butterflies; some old favourites and one completely off the radar “extinct” species.

 

Island Life – Part 1

I’m just back from a fabulous week in the Isles of Scilly. I went with my long-suffering sister and her partner and their two dogs. I say long-suffering as they had to spend a week with my constant exclamations of  “ooh look at that beetle” and “wow a bee” and “can we go and see puffins” again and again! All I can say is that they’re very tolerant people.

The Isles of Scilly are a small group of islands off the Cornish coast. They may only be about 28 miles from mainland England, but they feel like they’re somewhere far more exotic. With a mild maritime climate, tropical looking flowers flourish in a way I can only dream of back home in the relatively cold climes of Worcestershire. The gardens on Tresco are world famous, but the plant life proliferates everywhere. I particularly liked the Angel’s Trumpets (left) and the tall spikes of Echium that crop up all over the islands. Here’s a couple of the more alien looking species from the Tresco gardens.

With an abundance of flowers comes an abundance of insects, particularly bees. The Echiums must have been several metres tall and were alive with bees making the most of the tall floral spikes. Elsewhere even the clover covered grass in gardens was humming with bees, in far greater numbers than I get at home. My favourite spot though was this leaf-cutter bee taking a break or perhaps regretting cutting such a large piece of leaf.

We saw some cracking beetles too as we walked the coastal paths. This Rose Chafer beetle was a stunning iridescent green and huge (I regret not sticking a finger in the photo for scale here). If you’ve ever read the book Miss Benson’s Beetle (and I highly recommend it) then you’ll understand I had a bit of a Miss Benson moment finding this.

We also found a pair of these large black beetles on another path in Bryher. I think it’s an oil beetle, but more than happy to be corrected if it is not.

I did miss my moth trap while we were away. I had briefly considered packing a portable one, but where we were staying wasn’t really suitable for moth trapping without annoying the neighbours, so I resisted. I did get a bit of a moth fix in the form of hummingbird hawk-moths which popped up all over the place – even when we were on a boat out at sea. Many thanks to my sister for managing to catch this one on video with her phone.

 

So that’s probably enough of me sounding like an advert for Scilly for Part 1, I’ll be back soon with birds and mammals for Part 2.

Hawk Surprises

I’d been feeling the need to feed my moth mania for a while now and share some mothy photos, but hadn’t really got a theme in mind. Then this week a surprise moth in the trap provided the necessary inspiration – a blog post about hawks!

I’ve been lucky enough now to see 10 species of hawk-moth in my garden. Most are fairly common, but a couple have been rare migrants that were beyond my mothy dreams. I love all moths, but there’s something really special about spotting a new species of hawk-moth in the trap.

The first hawk-moth I ever saw, before I even got into moths, was the Humming-bird Hawk-moth. These amazing moths, don’t look that exciting when at rest (photo left), but when they take off and buzz from flower to flower, they really do what it says on the tin and look like miniature hummingbirds. I’ve always wondered what these moths were called before we discovered the Americas and saw hummingbirds? They are still a highlight of my summer when they appear, often seeking out the red valerian or the buddleia in the garden.

They’re so quick it’s hard to get a decent photo or video, but here’s a brief clip of one from a few years ago.

The first of the big hawks I ever caught in a moth trap was the Elephant Hawk-moth. It was my first summer of moth trapping and I can still remember the feeling of absolute incredulity that I could have found this incredible big pink moth in my own garden. They still thrill me now and are my go-to moth when people say moths are dull brown things!

I am lucky enough to also get the Small Elephant version, not as big (obviously) and flashy as his counterpart, but a striking beast nonetheless.

The next most common hawk I get is the Poplar Hawk-moth. These large moths appear every summer and have a striking way of holding their wings sort of out from their bodies.

A slightly less frequent visitor is the Lime Hawk-moth. These come in two colour variations. The most common one I get is the typical green and pink form, but I have occasionally had the more unusual brown variant.

The next hawk will always hold a special place in my heart as I managed to raise one from an egg – the Eyed Hawk-moth. I did a whole blog post about Lonesome George (as the egg/caterpillar became known) which you can read here https://toolazytoweed.uk/2019/08/29/lonesome-george/ and https://toolazytoweed.uk/2020/05/22/lonesome-george-born-free/. But for now here’s a photo of him in all his adult glory.

The next hawk I’ve only seen twice in the garden and neither have been exactly pristine specimens, both worn and well passed their best. But still a thrill and totally unexpected to see such a large moth in the trap.

The next one has only graced the moth trap once – a Privet Hawk-moth. This is not a particularly common moth in Worcestershire, so it was a real surprise to get one in the trap. And it was big, much bigger than the other hawks I’ve seen!

The final two hawk-moths were real surprises. Neither are resident in Worcestershire, but are rare migrants, so I’d never dared hope to see them. But in 2019 I saw a few social media posts about Bedstraw Hawk-moths being seen. Each night I’d hope for one to arrive in Malvern, but never really expected it to happen. But then at the beginning of August, I saw it sitting in the trap – a dream come true. It’s surprisingly nerve-wracking getting a moth like this out of the trap – terrified it would fly off before I could get a photo as proof.  But proof I have and I must admit it was glorious to be able to post on social media that a Bedstraw Hawk had deigned to visit my garden. People literally came from miles around to see it.

So I didn’t think I’d ever beat my Bedstraw, but just this week the moth gods favoured me again. I’d been seeing posts from Cornwall with people trapping multiple Striped Hawk-moths, but as a rare migrant I didn’t imagine one would ever reach as far north as Malvern. But the winds must have been blowing in the right direction and on Monday I got up at the crack of dawn to find a Striped Hawk casually sitting in the corner of the trap – unbelievable! I only recognised it because I’d seen the Cornish photos, as otherwise it wouldn’t even have been on my radar as a possibility. Not taking any chances, I took a few photos through the Perspex of the trap, before opening the trap to get it out. Some better photos later on and I could once again bask in moth-envy from my fellow moth-ers.

The West Midlands moth website lists 16 species of hawk-moth, so to have seen 10 species in the garden is pretty amazing.  Of course there are still those moths of legend that I’d love to see – the Convolvulus and Death’s Head Hawk-moths being the ultimate dream moths – but there’s always another moth trap and you never know your luck!

 

The Blog is Back!

Hello again!

It may seem like I’ve just been Too Lazy To Blog, and I can’t deny there’s an element of that, but mainly life in the form of a very difficult 3 years has just got in the way. But hopefully now things are getting back on an even keel and I can resume my wildlife ramblings. The weeds in the garden have continued to grow and there’s still plenty of wildlife to be seen, photographed and waffled on about. So the blog is back!

I may not have been blogging, but I have seen a lot of amazing stuff in the last 3 years. Maybe not attack ships on fire off the shoulder of Orion (who doesn’t love Rutger Hauer), but all sorts of other interesting things. So in no particular order, here are some of the highlights of the last few years.

In December 2023 there was a lot of excitement on Twitter/X about Waxwings being seen in and around Malvern. Like many others I grabbed my camera and headed out in search. Not only did I eventually get to see them, but I made a new friend in the process, without whom I’d never have found them, so a definite win-win situation.

Last summer I was really excited to see my first ever glow worms. Tiny little green glows at a reserve just a few miles from home.  Not easy to spot, but once you get your eye in they really do what it says on the tin and glow a bright green. I only had my phone with me, so this “magnificent” picture will probably go down in history as one of the most atrocious photos ever. Perhaps I should just give it an abstract name – “Green Glow on Black Canvas” or something. But it’s the only proof I have that I saw a glow worm, so here it is!

In October last year I finally got to see the Northern Lights and from my back garden. Not quite the awe-inspiring spectacle you see photos of, but definite streaks of pink and green nonetheless. Again I’m probably up for some kind of award for awful photography for this, but I’m just happy to have finally seen this. Twenty odd years living in Scotland and I finally see it in Malvern!

I’ve had a few days out and about doing some not-strictly wildlife things, but it was out in lovely countryside so I reckon that counts. In August last year my sister and I went whinberry picking for the first time since we were children. Whinberries (or Wimberries, Bilberries, or Blaeberries, depending on where you’re from) were our Dad’s favourite and grow wild in the Shropshire hills. We were a bit late in the season, so only managed to gather enough for a very small pie, but it was well worth it – the taste brought back many happy childhood memories and we certainly got to see a lot of the wilds of Shropshire while we hunted for them.

We also had a slightly bonkers trip to see the famous cheese rolling race in Gloucestershire. I must stress we valued our lives and vertebrae too much to actually take part chasing a 4 kilo wheel of Double Gloucester down a very steep hill. It was hard enough climbing high enough to watch it, without hurling ourselves at break-neck speed back down again. But it was a glorious spectacle when viewed from a safe distance.

There have been lots of moths recorded in the garden in the last few years, but I’ll post about those separately. One interesting moth seen while venturing outside the garden was a Lunar Hornet Moth. These stunning moths don’t really look like moths with their clear wings and hornet like bodies. Their caterpillars live in the wood of old trees and the adults are attracted to pheromone lures.

Other highlights of the last few years include dolphin watching on a glorious sunny day in New Quay in Wales and a visit to the lovely Westonbury Mill Water Garden in Herefordshire just as the new season’s toadlets all emerged from the ponds. Never seen so many tiny toads (they were literally the size of a fingernail), it was virtually impossible to walk – we went round at a snail’s pace to avoid standing on them. Speaking of toads, I’ve also joined a local toad patrol – more of that in another blog post too.

There’s been a visit to the Diglis Fish Pass in Worcester. Our guide showed us fantastic photos of large salmon, pike and even otters swimming by the viewing window, although on the day, all we saw were a few minnows. Another day out took us to the confetti fields, also in Worcestershire. The delphiniums are grown specifically to turn into environmentally friendly confetti, but I actually preferred the wildflower borders around the main crop.

One final highlight of the last few years was a weekend in Harrogate for a slug conference! Harrogate is a really lovely town and a slug conference at Harlow Carr gardens to discuss the results of the slug survey I took part in, was a delightful, if slightly unusual treat! (as was Betty’s tearoom’s Fat Rascals!)

I felt ridiculously pleased that my garden had produced above average numbers of slugs compared to the other slug counters – something most gardeners would be horrified by, but I viewed it as a badge of honour for my scruffy garden.

So there are just a few hopefully interesting bits and pieces from the last few years. The plan is to start blogging again regularly, or at least not wait another 3 years before I can think of something to say.

 

Butterflies No 54 & 55!

Yes I’m creeping ever closer (albeit at snail’s pace) to my target of seeing all 58 species of butterfly in mainland Britain! Last week I had a lovely holiday just south of the Lake District near a village called Silverdale. As well as enjoying a relaxing week, the aim was to see 2 new species of butterfly – the Northern Brown Argus and the Mountain Ringlet.

The weather at the beginning the week was not on our side – grey skies, cooler temperatures and blowing a gale – not ideal butterfly spotting conditions. But after a couple of days, things had perked up enough to have a go for the first species – the Northern Brown Argus. We tried a couple of sites – Warton Crag nature reserve & Jenny Brown’s Point in Silverdale with no luck. Arnside Knott, a hill nearby, was going to be our next attempt, but we weren’t sure whereabouts on the hill to look. Then a stroke of luck on Facebook – someone had seen these butterflies at Arnside Knott the day before and very kindly posted a google map shot with the spots marked on. I headed over and it was as if the butterflies had seen the FB post too – they were spot on for the map location.

Finding them was one thing,  but photographing them was another. They were very small and very fast. The first one snapped was barely a record shot – enough to confirm it was indeed a Northern Brown Argus.

An hour or so of chasing butterflies madly around in the sunshine and I managed a few more respectable shots. On the upperside of the wings you can see the dark dot with the white outline which marks it out as a Northern Brown Argus (the dot and of course the location this far north).

On the underside of the wings, the forewing is missing a black spot near the base that would have made it a Common Blue.

No. 54 proved relatively painless in the end, but no. 55 was going to be more of a challenge. The Mountain Ringlet, as the name suggests, likes to live up hills – big hills! It is the UK’s only montane butterfly and I am not a montane kind of woman! But there was going to be no other way than to climb, so climb I did – up Irton Fell in Cumbria. Most of the people I met that day also seemed to be looking for the same butterfly, so at least I knew I was in the right place. It nearly killed me, but it was worth it – for the butterflies and the views.

As with the Northern Brown Argus, the Mountain Ringlet is small and fast. Fortunately its chocolate brown colour stood out well against the grasses and heather when it was flying; but once it went down into the grass it was virtually impossible to find. I saw quite a few of them but most eluded the camera. So the best I managed was this – blurry, but just about recognisable as a Mountain Ringlet –  hastily taken before it shot off again.

But at least butterfly no. 55 had been ticked off the list.

I’m unlikely to manage any more new species this year, so for now will remain 3 short of the goal – the Lulworth Skipper, the Scotch Argus and the Chequered Skipper will have to wait another year.

 

2021 – The Year of the Slug

Well we all started out with high hopes that 2021 was going to be better than 2020. I’m not sure it achieved that, but best to dwell on the positives rather than the (many) negatives of the year. So here’s a round-up of some of my wildlife highlights from 2021, including a catch-up on my clearly over-ambitious New Year’s Resolutions.

The main highlight was probably going to Norfolk. I had originally planned to go in 2020, but covid put paid to that, but I finally made it there in June 2021. I had a rental right by the river in Wroxham, so was surrounded by wildlife from the start – birds, dragonflies and even a resident pike.  I ticked off number 53 on our list of British butterflies with the gorgeous Swallowtail and saw loads of dragonflies and birds. As I write, this I’ve realised I never actually got round to blogging about the birds, so will have to do a bit of a summary of those in a separate post. I visited lots of nature reserves and it was great to see a completely different set of wildlife to that which I get back home in Worcestershire.

Back at home, there’s been plenty of interest in the garden. The moth trap has been running throughout the year, bringing 34 new species to the garden. This takes the total up to an amazing 438 species recorded since I started in 2013. I’d never have dreamed back then that I could get such a huge variety of moths visiting my modest suburban garden. Highlights from this year include whoppers like the Pine Hawkmoth and this Privet Hawkmoth:

At the other end of the size spectrum, there were some lovely micro moths, including this Pearl Grass-veneer – a species I’d been hoping to see for a while.

Another mothy highlight was finally getting to see the flightless female vapourer moth and not only that, but getting to watch her laying eggs on our garage wall.

More bee hotels went up last year and were rewarded with plenty of solitary bee activity. No new species recorded in the garden, but thrilled to finally catch a leaf-cutter bee actually cutting leaves.

 

The pond continued to delight and I spent many a happy hour there last year watching the wildlife. We got frog spawn in it for the first time and the newts were busy too. I would love to get toad spawn, but I gather they tend to be faithful to the ponds they were born in, so we will be lucky to get those – but I live in hope. We had plenty of dragonfly and damselfly activity, including home-grown damselflies hatching from the pond. Only one new species was spotted – this Blue-tailed Damselfly, bringing our total Odonata species list for the garden to 10.

We’ve had happy and sad news with our hedgehogs in the garden. The good news is that through the warmer months we were visited nightly by at least one, and sometimes as many as three hedgehogs. Lots of courtship behaviour witnessed on the cameras and a few heated hoggy debates over food or ladies. Some of the courtship was quite late in the year though and the inevitable result was at least one late litter of hoglets. While a second litter may seem like a good idea, the resulting hoglets often don’t have time to fatten up before the winter. The result was that in a 2 week period between the end of October and early November, I had to rescue 6 very underweight hoglets, 2 of whom were out during the day as well. None of these would have survived hibernation without intervention as they just didn’t have the fat reserves. The 6 were all taken to local rescues. Sadly despite the best efforts of the rehabilitators, 3 of them still didn’t make it.

Thankfully the remaining 3 have survived. One has even grown enough that he was released back in our garden during a mild spell. Hopefully the remaining 2 can be released back home in the spring too.

Despite all the enjoyment I’ve had from all of the above, the animals of the year have to be slugs! Not everyone’s favourite I know, but over the last year I’ve grown quite fond of them. For most of this year I participated in a nationwide slug survey and am now a slug fan. Some of the slugs are still being analysed back at slug HQ (a RHS lab), so I’ll have to wait a bit for the final conclusions. But slugs really reached the dizzy heights for me when one of the actual slugs from our garden featured on Gardener’s World – it doesn’t get more exciting than that!

As to last year’s New Year’s Resolutions, I think I’ve failed pretty dismally on most of them (as with most things, I blame this on Covid). Here’s what I set out to do and what I did or did not achieve:

  • Video a dragonfly emerging from our pond. I did see some damselfly larvae and found several exuviae on rocks and plants, but didn’t manage to see them actually emerge in our pond. But I did see some emerging while we were in Norfolk, so can I count that???
  • Expand the moon garden – nope – the moon garden is stuck at the same size it was last year. I still had a good year for moths, but there’s always hope for more.
  • See 2 more species of British Butterfly. Only managed to see 1 more, but it was the fabulous Swallowtail, so more than happy with that.
  • Visit 5 new nature reserves. I think I did do that if I include the ones I went to in Norfolk.
  • Rockpooling. Nope – only managed to see sandy beaches in Norfolk, so no chance for rockpooling.
  • Go and see some wild Ospreys. Nope and again I blame Covid for travel restrictions during Osprey season.
  • The moth tattoo! Maybe I should give up on this!

So what about resolutions for 2022?

  • Continue the quest to see all the British species of butterfly. So far I’ve seen 53 out of the 58. I’m hoping to holiday in the Lake District this year, so with luck might be able to tick 2 more species off the list.
  • I had planned on starting a nature journal, recording the daily goings on in the garden. But as I write this, we are already on the 9th of January and I haven’t made a single journal entry – maybe I can start it in the spring?
  • Rockpooling. I would still really love to be able to film some wildlife in a rockpool with the GoPro. Hopefully there will be some rocky coasts round Cumbria to try this out.
  • Try a night-time safari in the garden. While doing the slug surveys, I was amazed how much invertebrate life was active after dark. So it would be nice to spend a night seeing the other side of our garden life.
  • Do a wildlife audit of the garden – hopefully this will be a lot more fun than that makes it sound. I already know how many moths and bee and dragonfly species we get, but I thought it would be interesting to tally up ALL the species we get. Since we’ve got over 400 moths alone, the total species count should easily make it over 500.
  • The moth tattoo – one of these days.

So despite a pandemic’s efforts to put a dampener on 2021, there was still much to enjoy in terms of wildlife. Being blessed with an interest in wildlife can be a real life-saver when so much of the rest of the world is doom and gloom. There is always something in nature to lift your spirits, whether it’s spotting some exotic bird or getting a slug on Gardener’s World! xx

Showbiz Slugs

Last November I joined 59 other volunteers in a project monitoring the slugs in our gardens. Our Slug Count Survey was being run by the lovely Imogen as part of her PhD with the RHS and Newcastle University. Once every 4 weeks we had to go out into our gardens and collect all the slugs we could find in half an hour. We’d then attempt to identify them, before posting them off to Imogen for “proper” identifications.

This year has flown passed for any number of reasons, but I still can’t believe my year of slug counting is already up. It took a bit of explaining to my neighbours as to why I went out each month with a head torch in the dark to wander round the garden with a bucket of carrot shavings (food for the slugs) for half an hour, not to mention explaining to the lovely lady in the post office why I was posting slugs! I actually found it really interesting to go out in the garden after dark and just look at what was around. I was used to going out to check on the moth trap, or feed the hedgehogs, but tended to be focussed on those activities. Searching for slugs, I noticed for the first time all the caterpillars that were out and active, the worms on the grass that vanished as they felt my footsteps approach and the spiders and woodlice and all manner of other species going about their business at night. The garden at night becomes a whole other world.

In total over the 13 counts, I sent off an amazing 1145 slugs! You’d think that might have reduced the population in my garden, but they are still very abundant. Going out the night after a count there seemed to be just as many slugs roaming the garden as before, with no sign of diminishing populations.

And the slugs themselves were clearly doing their bit to increase numbers.  Through September there were several nights when I saw pairs of large Arion slugs trailing each other round the grass. There is clearly a season for it, as I saw multiple pairs for a couple of weeks, but none before or since.

Whatever romancing was involved, it was clearly successful and I can presumably expect more Arion slugs next year.

As well as getting to see a bit of slug romance, I was really chuffed to film one of the Arion slugs getting its wriggle on. This squirming action in the video below is a characteristic feature of a couple of Arion species when disturbed.

The total number of species recorded has yet to be finalised (some are apparently getting sent for DNA analysis!), but is probably around 14. There were at least 4 species of short-keeled slugs, including this Ambigolimax sp.

There were at least 7 species of round-backed slugs including the familiar large Arion species. Finally there were 3 species of the long-keeled slugs. The one below is the Crimean Keeled Slug (Tandonia cristata) which has a network of dark lines criss-crossing the body.

My most unusual find was a Worm Slug (Boettgerilla pallens), another long-keeled slug, which as the name suggests looks like a worm! I only found 1 in all the surveys.

Finding the worm slug was good, but the best was yet to come. Our survey leader appeared on BBC’s Gardener’s World in July to try and convince the (possibly sceptical) viewing public of the delights of slugs. As part of the feature there was footage of several specimens. I was beyond excited when she told me that one of my actual slugs had been filmed for the show. Here’s a still from iPlayer showing my very own slug TV star (a Netted Field Slug, Deroceras reticulatum).

Not only did my slug feature, but it was described as being one of the biggest pest species, doing the most damage to plants. I don’t know why, but I felt ridiculously pleased that I’d got effectively the bad boy of the slug world!

So all in all this slug project has been fascinating. I love doing these citizen science projects. You usually learn something new, or see something new and either way you get the pleasure of enjoying some aspect of nature whilst contributing hopefully useful data to scientists. This particular project has given me a whole new appreciation for slugs, a group I’d previously given little thought to. I know they are not popular with gardeners and they can be a worry for those with hedgehogs in their gardens (slugs can carry parasites such as fluke and lungworm which can pass to the hedgehogs). But everything has its place and slugs have just as much right to be in a garden as everything else.

 

Flightless but Fabulous

This week I finally got to see a moth I’ve been wanting to see for a very long time – a female Vapourer. We often see Vapourer caterpillars in the garden and sometimes the male adult moths, but the female is something else. The female Vapourer has the, perhaps unenviable, trait of being flightless! Her life as a caterpillar proceeds the same as the male, but when she pupates, instead of emerging with beautiful wings, she appears as short dumpy lump who can hardly move (perhaps this is why I empathise with her!). A female Vapourer’s lot is not a glamorous one.

Back at the beginning of July I spotted this large Vapourer caterpillar on the garage wall. They are spectacular looking caterpillars with tufts protruding here, there and everywhere. 

This caterpillar very purposefully headed up the garage wall until it reached the overhang at the top – and there it settled. I saw it there an hour or so later and at first thought it had been snared by a spider’s web, but it was in fact pupating.

The caterpillars spin themselves a fairly thin whispy cocoon and can emerge as an adult within 2 weeks. The good people on a local Facebook group suggested this could be a female, so I checked the cocoon every day for weeks hoping to catch it emerge. Sadly just as the time should have been up, it looked like the garden sparrows or blue tits had pecked her out of her cocoon. We often see them pecking at small spiders and insects on the walls and it seemed this was her fate.

Fortunately that same week, I spotted another 2 caterpillars – also on the garden wall, but this time choosing a slightly safer place to pupate – beneath the garage windowsills. Tucked away there, they were less visible to the birds and perhaps stood a better chance. These ones also had the advantage (for me) of being much lower down the wall, so I could watch them more closely. The caterpillars (at this stage I didn’t know whether I’d got males or females) use some of their hairs and tufts to “decorate”  the cocoon. Since these hairs are irritants, this may serve to provide additional protection to the developing moth inside. You can see various hairs and tufts on the picture below, photographed under the windowsill.

On Sunday, exactly 14 days after I’d seen her crawl under the windowsill, a female Vapourer emerged. When they emerge the females emit pheromones to attract the males. Since the females can’t really move, the males have to come to them and the pheromones draw them in very quickly. So quickly in fact that I missed this stage of the process. I’d checked the cocoons at about 8am – no sign of any activity. I was out for the morning and by the time I checked again at noon, the female was in full egg-laying mode. The males had been and gone. Disappointing as that was, it was still fantastic to see the female laying eggs. Here are a selection of photos taken somewhat awkwardly beneath the windowsill.

Her body is really a furry sac, stuffed full of eggs. She has legs at the front to hold onto the cocoon. On the photo below you can see what I think are the vestigial remains of wings – looking like fluffy ears, either side of her head.

The eggs are laid directly onto the cocoon. They looked wet and a sort of olive colour as they emerged but soon turned white with a darker centre spot.

I did try to video the process, not easy as the light wasn’t great underneath the windowsill. She works determinedly laying egg after egg, all neatly arranged on the remains of the cocoon.

In all she laid 401 eggs – I read online that they can lay between 200 and 400, so she excelled herself!

I suppose I should show a photo of a male Vapourer, although their contribution to the whole process is fleeting to say the least. He is, it has to be said, a very attractive moth, with large feathery antennae for detecting the females’ pheromones.

Sadly once the female finishes laying her eggs, she dies. Her body by then has shrunk and shrivelled once it is empty of eggs. I found this one the next day lying on the ground beneath the windowsill, her eggs still safely sitting on the cocoon. I actually felt quite sad to see her like that, but her work was done and with 401 eggs she had hopefully ensured her genes would live on. Her adult life may have been brief, but she packed a lot into it. Flightless she may have been, but to me a fabulous moth.
