National Moth Week

/ nrowberry / 3 Comments

It’s National Moth Week (or International since it’s worldwide) and for once I’m on the ball enough to be blogging on time and on topic! This is mainly due to the fact that I read a lovely blog post this morning on this very subject by Nature is My Therapy: https://natureismytherapy.com/2022/07/26/moths-not-just-for-after-dark/  So thank you Kim for the timely reminder.

National Moth Week celebrates the beauty and diversity of moths, a sentiment close to my heart as I’ve been fascinated by the moths in my garden since I started trapping in 2013. This week, after 9 years of moth trapping and perfectly timed for National Moth Week, I recorded the 450th species of moth in my garden! I never dreamt when I started looking at moths that I’d find anywhere near this number in my suburban garden. Just goes to show you don’t know what’s out there until you start looking. Of course of those 450 species, some have only been recorded once – often migrant moths just passing through. But a good chunk of the species are regular attendees at my moth trap.

So here is no 450 – the Brown-Line Bright Eye (Mythimna conigera) – so called because (not surprisingly) it has a brown line and a bright eye spot.

Coincidentally the same night I also trapped the very similarly named Bright-Line Brown-Eye (Lacanobia oleracea). So here they are side by side.

I trap 2 or 3 times a week through the summer and usually once a week in the winter. I started this year with a running total of 438 species, so another 12 have been added since then. Of the new ones, a couple are ones I’ve wanted to see for a while and others haven’t even been on my radar. The longed for ones include a Nut-tree Tussock a (Colocasia coryli) and a Muslin Footman (Nudaria mundana).

Of the more unexpected ones this Italian Tubic (Metalampra italica) micro moth was rather lovely and one I’d never even heard of. Apparently it’s a recent colonist that’s spreading north from the south of England.

So the trap is out again tonight and I’ll be up at the crack of dawn to check the contents, hopefully before the robin beats me to it. It’s one of the things I love about moth-trapping – you never know what you’re going to get – it’s like Christmas morning for moth nerds!

Happy National Moth Week everyone.

 

Showbiz Slugs

/ nrowberry / Leave a comment

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.

 

Big Garden Birdwatch 2021

/ nrowberry / 4 Comments

Another year, another lockdown; or more cheerily – another year, another Big Garden Birdwatch! The perfect thing to do for an hour when you can’t leave home.

Saturday it pretty much poured with rain all day, so today seemed like a better birding day. It was still bloomin’ cold sitting there though for an hour and my derrière was pretty numb by the time I finished.  Still it was worth it to record a very respectable 34 individuals of 12 species.

Top of the abundance was, as usual, the house sparrow. I  counted at least 12 in one go, although I’m sure we actually have more than that. Joint second were the blackbirds and jackdaws – 4 of each. I can’t tell the difference between male and female jackdaws, but for the blackbirds there was one female and at least 3 males.

Most of the rest arrived in pairs – goldfinches, great tits, collared doves, wood pigeons, starlings and magpies, although I only seemed to manage to get photos of them one at a time.

And then there was a singleton blue tit, dunnock and robin. The robin was the most sociable of the whole bunch. He even landed on the camouflage netting right by my head – too close to even get a photo. As if sensing that he might be missing his photo op, he then obligingly hopped down to some stems in front of me and posed so I could get his good side. Of course there was still a twig in the way – isn’t there always?

The (almost) highlight of the whole hour came near the end when I think a sparrowhawk zoomed across the garden after a small bird. Unfortunately it all happened so fast that I couldn’t be sure that’s what I saw and I almost got tangled in the camouflage netting in my haste to stand up and get a better look. So although I’m about 80% certain it was a sparrowhawk, I wasn’t sure enough to include it in my birdwatch results. So close!

A bit disappointed that our wren didn’t put in an appearance, nor the long-tailed tits. And really disappointed that our male blackcap was a no-show too. He’s been pretty much resident outside our patio doors for the last 3 weeks, but today of course he chose to have the morning off. Just to prove it, here he is from a few weeks ago.

Submitting my data took a few goes as the RSPB website seemed to be struggling. Hopefully that’s a good sign and means lots of people have been doing the count.

Success in the end though and nice to know I’d contributed in a small way to another bit of citizen science. Talking of which, tonight happens to be my next slug collection night for the Slug Count project. It’s all go!

2020 – The Year of the Pond

/ nrowberry / 4 Comments

Well there are probably lots of ways to describe 2020, but most of those aren’t repeatable on what tries to be an upbeat blog. So I will gloss over the obvious and instead try and focus on the many good things that happened in the last year.

First and foremost was that we finally managed to put in a new pond. The timing for this couldn’t have been better – the pond went in during February and of course in March we went into lockdown. Having the pond to sit by and watch develop through those long months was a real sanity-saver. It was amazing how quickly the wildlife moved in and as it matures I’m sure it will only get better.

A real highlight and sense of achievement came at the end of May when George, the Eyed Hawkmoth I’d reared from an egg, finally emerged. I’d been nurturing him for 10 months since I’d found the egg in the moth trap and so I felt like a proud mum when he emerged and flew off into the night. Hopefully there will be sons and daughters of George in flight this summer too.

Another moth related achievement was the creation of our Moon Garden – an area planted specifically to attract moths. And it worked. 39 new moth species were recorded, bringing the running total for the garden to 405. Best of all it attracted a Dark Crimson Underwing – believed to be the first record for this species for the whole of the West Midlands.

2020 turned out to be a good year for butterflies too. Between lockdowns, we managed to add 2 more species (Silver-spotted Skipper and Black Hairstreak) in our mission to see all the British butterflies. We also noted 2 new species for the garden (Silver-washed Fritillary & Brown Argus), although this was more by luck than good management.

The new bee hotels provided lots of interest and again we added 2 species to our garden count (Willughby’s Leafcutter and a Sharp-tailed Bee). Being able to watch both Red Mason & Leafcutter bees build their nests in the tubes was really fascinating.

Despite lockdowns, we still managed to take part in various citizen science projects – including Big Butterfly Count & Garden Moth Scheme. A new project this year is the Slugs Count project.  This is a monthly survey of the garden for slugs and it’s been great (trying) to get to grips with a whole new group.

As I do every year, I’d made various wildlife resolutions at the start of 2020. Of course back in January none of us had any idea of how the year was going to turn out! Not surprisingly the Covid imposed restrictions had an impact on some of my resolutions, but at least this year I’ve got a really good excuse for not completing them all! So here were last year’s targets:

  • New pond – well at least we smashed this one. Many thanks to Gwyndaf the Cycling Gardener who was the one who did all the hard work digging, while we sat back and reaped the rewards.
  • Create a Moon Garden. I think we pretty much nailed this one too. The Moon garden was a big success both aesthetically and for the moths.
  • See 2 more species of British Butterfly. For a while it seemed touch and go whether we would achieve this one. Our planned trip to Norfolk to see the Swallowtails was of course cancelled, but in the end we did manage 2 other species (always good to have a plan B). So we’ve now seen 52 of the 58 species.
  • Visit 5 new nature reserves. I think we only managed 2 new ones (Glapthorne Meadows and Aston Rowant NR), but then many of the nature reserves were closed to the public during the lockdowns, so I figure we have an excuse.
  • Go rockpooling. Had hoped to do this one in Norfolk, but of course that went out the window. Not much scope for rockpooling in Worcestershire, so this one will have to get bumped to next year.
  • Go and see some wild Ospreys. Again we were thwarted by Covid. I had hoped to go up to see the Dyfi Ospreys, but for a large part of the year we’ve not been allowed into Wales!
  • The moth tattoo! I genuinely thought this would be the year I’d get a moth tattoo – I’ve even decided it should be of George the Eyed Hawkmoth. But of course tattoo parlours were one of the first things to get closed down – so that’s my excuse at least.

So to New Year’s Resolutions for 2021. Covid may continue to thwart our efforts, but we can at least hope to enjoy as much wildlife as possible.

  • Try and video a dragonfly emerging from the pond. We had lots of dragonfly/damselfly egg laying activity in the new pond last year, so hopefully I can catch some of them emerging in the summer.
  • Expand the moon garden – it’s been great so far, but I’m hoping to double the area.
  • See 2 more species of British Butterfly. We’ve now seen 52 of the 58 species, but we’re having to go further and further afield to see the remaining ones. Fingers crossed we can see the Swallowtail in Norfolk at least this year.
  • Visit 5 new nature reserves.
  • Rockpooling. Again fingers crossed we make it to Norfolk for this.
  • Go and see some wild Ospreys – if we’re allowed back in Wales!
  • The moth tattoo!

If 2020 has taught me anything it is that I am very grateful to have a wildlife filled garden and that I am lucky it brings me so much pleasure. It must be awful for those who didn’t get the chance to enjoy wildlife this year, but then I think it would be awful in any year not find joy in the nature that is all around us if we take the time to look.

Our Garden Butterflies

/ nrowberry / Leave a comment

The Big Butterfly Count results were announced last week, so it seemed a good time to take a look at the butterflies we’ve had in our own garden this year. Sadly the Big Butterfly Count suggested a poor year for butterflies, although the very warm spring may have meant their numbers peaked before the Count took place – let’s hope that’s the reason.

It might not have been a great year nationally, but we have actually done pretty well here in the garden. By the end of 2019 we had recorded 18 butterfly species in the garden in the 12 years or so we have lived here. In 2020 we were very pleased to add two more to that list.

In the middle of July I was amazed to spot a Silver-washed Fritillary in the garden. It was a bit tatty and probably a bit lost, but you take what you can get with wildlife sightings! Having an overgrown, brambled covered garden had paid off. For once I even had the camera to hand, so snapped a few photos before dashing (artistic license here for the speed) back into the house shouting for Chris to come out and see. It moved from the brambles to a buddleia and we both managed a few more photos before it realised it probably wasn’t in the right place and flew off.

Seeing a Silver-washed Fritillary in our own garden was particularly enjoyable as, thanks to Covid, we hadn’t manage to get out to many of our usual places, so hadn’t seen them anywhere else this year.

Then a couple of weeks later we were sitting by the pond (as so much of 2020 has been spent) when a small butterfly landed on the Eryngium flowers. We thought at first it was a female Common Blue, which in itself would be a bit of a rarity in the garden, but it turned out to be a Brown Argus – our 20th butterfly species for the garden.

Besides the newcomers above, we’ve had a fairly steady stream of butterflies throughout the summer. As with the Big Butterfly Count results, the white butterflies were the most numerous ones – Small Whites in particular seemed to have a good year here in Malvern. I try and record the butterflies I see daily for the Garden Butterfly Survey and for most days through the summer I was seeing at least some Small Whites and some days up to 8 or 9 in one go.  The numbers of Painted Lady butterflies we saw were down on last year, but then last year was a particularly good year for them nationwide.

Commas, Red Admirals, Peacocks and Small Tortoiseshells all appeared, although never in more than 1s or 2s, despite us having a lot of Buddleias in the garden. The grassy areas (we can’t call them lawns any more) produced Ringlets, Gatekeepers and Meadow Browns and the Speckled Woods & Holly Blues liked the brambles and apple tree. I’d planted up a few Bird’s Foot Trefoils in the hope of attracting some Common Blues, so was really chuffed when one finally deigned to appreciate my efforts and land on the flowers.

The final treat for the year was a second brood Small Copper which took advantage of some of the late summer Asters growing wild all over our garden. It’s got blue spots in the wings which apparently makes it the caeruleopunctata form, which was an interesting snippet to learn about.

So it may not have been particularly good news nationally for butterflies, but it seems our Malvern garden has been lucky.  Whether we’ve genuinely had more species visiting or whether we’ve just been seeing more because, thanks to lockdown, we’ve spent more time in the garden I don’t know. Whatever the reason, they have certainly been very welcome little rays of sunshine in an otherwise troubled year.

Big Garden Birdwatch 2019

/ nrowberry / 3 Comments

It’s that time of year again – the Big Garden Birdwatch. I think every year I write a similar post about that mixture of anticipation and frustration that this fantastic bit of Citizen Science brings. The usual feeling of “where have all my regular birds gone” followed by the joy a pair of blue tits bring when they appear in the nick of time to make the cut. The red kites last week were undoubtedly magnificent, but when you’ve been sitting freezing your proverbial off for an hour, the sight of a pair of blue tits can be just as rewarding.

I did our garden count on Sunday, an unfortunately blustery day, which I presume is what put a lot of our birds off; rather than just sheer wilfulness to avoid being counted. In the end I only recorded 27 birds of 7 species – way below our garden norm and less even than I can see just glancing out now.  But data is data, so I hope our paltry count will still be of use. So all I saw was:

  • 14 sparrows – there may actually have been double that but, they were in the bushes and impossible to count more for certain.
  • 2 collared doves
  • 1 wood pigeon
  • 2 magpies
  • 1 blackbird
  • 5 jackdaws
  • 2 blue tits

I did try to take photos of those that landed on the bird table, but our overgrown teasels were flapping about in the wind in my line of sight, so I only managed one of the jackdaws.

The blue tits were a bit easier as they were feeding in the apple tree closer to the house.

While, I watched a mainly empty garden, Chris took himself off to his workplace and did the Birdwatch there. Bird envy is a terrible thing, so I tried to be pleased for him when he came back with these photos of a Grey Wagtail and Chaffinch.

So that’s it over for another year. Apparently this year was the 40th anniversary of the Big Garden Birdwatch. It started as a survey just for children to do, but thankfully us adults are allowed to join in now too. Our garden birds often seem to make themselves scarce during this annual count, but it still gives me an enormous sense of satisfaction to know that we’re contributing to a really useful bit of science. And sitting just quietly watching the wildlife in your garden for an hour, with no interruptions or distractions is no bad thing either!

 

Clouded Yellows & Big Butterfly Count

/ nrowberry / 5 Comments

For one reason or another I’ve not had the chance to blog this last month, despite it being full on Butterfly Season. So to make up for lost time, this blog post is a bit of a catch up on all things butterfly in the Too Lazy world. Firstly we’re still in the midst of the Big Butterfly Count – one of the biggest citizen science projects in the world.

As I type this there have already been over 74000 counts and there’s still a few days to go. So if you haven’t done it already, get along to https://www.bigbutterflycount.org/ and find out what it’s all about.

We’ve done several counts in both the garden and down the allotment. The lottie produced, not surprisingly a lot of “Cabbage Whites” – in reality a mix of Large, Small and Green-veined Whites. In the garden, our first common blue of the year obligingly turned up in time to get counted. Similarly it was nice to count Painted Ladies and a Red Admiral to add to the tally of Whites, Gatekeepers and other garden stalwarts.

A trip to Trench Wood in early July was prompted by reports of large numbers of Purple Hairstreaks coming down and settling low enough to get photos. Seemed too good an opportunity to miss. Trench Wood is always a delight and this year was no exception. The wood was full of the usual Meadow Browns, Gatekeepers and Ringlets, plus plenty of Whites and White Admirals.

The ever gorgeous Silver-Washed Fritillaries were also out in large numbers, tropical looking as they bombed around the open rides.

My target species for the day – the Purple Hairstreak – didn’t disappoint. Almost as soon as I left the carpark they were visible along the path, settling comfortably on the bushes either side. The reports I’d read hadn’t exaggerated – there were too many to count and I’ve never seen them settle so well at a reachable height!

A quick trip to the nearby Guarlford Straights gave me the chance to see some lovely butterflies practically on my doorstep. Common Blues were probably the commonest species, flitting about the dry grass in the sunshine.

Amongst the Common Blues I found at least one fairly fresh looking Brown Argus. It’s only a couple of years since we saw our first ever one of these, so it’s still a bit exciting to spot one.

Small Coppers were also reasonably common. Athough none would pose nicely with their wings open, I found the underside of the wings to be just as beautiful in a more subtle colour pallet.

Finally the high spot of the last few days was a trip to Venus Pools in Shropshire. It’s a small reserve (with as the name suggests, some pools) run by the Shropshire Ornithological Society, but it’s also really good for butterflies. In particular, Common Blues were everywhere – they should be renamed Abundant Blues! We’ve never seen so many in such a small area, including several courting couples like these.

Amongst the Common Blues, were the occasional Brown Argus and Small Copper.


Also present were Painted Lady, Small Tortoiseshell, Large, Small & Green-veined Whites, Speckled Wood, Gatekeeper & Meadow Browns. But the real reason we’d driven 50 miles was reports of Clouded Yellow butterflies. For two weeks prior, we kept seeing gorgeous photos of Clouded Yellows at Venus Pools on social media. Having never seen one, this seemed the perfect opportunity. We spotted our first one almost immediately – unmistakeable bright yellow, but very, very fast. Only once did one stop long enough for us to grab some quick photos.

So not the finest pics, but recognisable enough to count as butterfly no. 47 on our quest to see all the British species. Well worth the 100 mile round trip! So all in all this last month has been a butterfly filled delight. Fingers crossed all this hot weather won’t spell trouble for the caterpillars and next year’s butterflies.

 

 

Big Garden Birdwatch 2018

/ nrowberry / 6 Comments

Last weekend was the annual Big Garden Birdwatch – one of my favourite bits of citizen science to participate in. Unfortunately it was one of those dull, grey January days where the sun just doesn’t come out – and nor did many of the birds. Coupled with that, my camera was in for repairs so I couldn’t even take photos of the ones that did appear. I persevered though as it would have been a shame to miss out on it this year, having done it for the last few years.

So I spent an hour crouched behind my camouflage netting hoping neither the birds nor the neighbours could see me (neighbours think we’re mad enough as it is without seeing the camouflage!). As always seems to be the case, the birds which moments before had seemed so plentiful, all disappeared as soon as I got my notepad out. But my masterplan worked as I’d topped up all the bird feeders just before and they couldn’t resist indefinitely.

The sparrows were abundant as usual. I’ve no idea how many we really have visiting the garden, but I’m sure it’s much more than the 13 I managed to count in one go. I suspect we have closer to 25 or even 30, but they’re impossible to count all together, so I stuck with the 13 definite that I could see at once.  Next largest presence was the jackdaws – 5 of whom put in an appearance on the bird table. These are at least big enough and obvious enough to be much easier to count.

The rest of the birds came in just ones and twos: blue tits, robin, blackbird, goldfinches, starlings, woodpigeons, crow, dunnock, blackcap (female) and magpie. A total of 32 birds of 12 species. As usual I had several no shows – birds that have graced our garden in the days before and days after the count. These include the wren, great tits, coal tits, long-tailed tits and chaffinch – all of whom I’ve seen today.

The RSPB give you a nice little pie chart when you upload your results. It only shows 10 species, so misses out the crow and the blackcap, but at least represents 30 out of the 32 birds I saw.

You can also get a similar representation of the national results so far. So as of this afternoon, sparrows were leading the way nationally, as they were in our garden. But there was no sign of our second most abundant bird, the jackdaw, in the nation’s top 10. Perhaps we are just in a hotspot for jackdaws, or they particularly like the selection of bird food we put out here?

This year’s results for our garden were very similar to last year’s (https://toolazytoweed.uk/2017/01/28/big-garden-birdwatch-2017/). So it’s good to know there are no dreadful declines here at least – keep putting out the bird food and they will come!

While I was skulking around the garden, Chris went for a walk near his work in Malvern. He didn’t do a bird count as he was moving around too much, but he did see a few more interesting birds than I did.

Jackdaws we do of course have in the garden, but I liked this fluffed up one.

Although Chris did at least have a working camera, unlike me, he was still plagued by the same dull grey light that made taking decent photos a bit difficult. So apologies that these next 3 photos aren’t exactly fabulous, but the birds themselves were. A great spotted woodpecker, a kestrel and a tiny goldcrest. Not a bad trio to spot on one walk.

And as if seeing all of those wasn’t good enough, he even managed to come home with some decent photos of a wren. It’s obviously not the same wren that torments me daily in our garden (I swear it danced in front of the window today knowing I still have no camera), but it’s great to get any decent wren photos. I couldn’t decide which one I liked best, so here are my favourite 4 photos.

So a bit of birdy citizen science for one of us and a bit of bird photography for the other. A weekend well spent I reckon.
