Lively larva

I took this short video back in November but had so much other material to share that it never got posted on YouTube until now. You might think hoverfly larva are slow and ungainly but just look at how quickly this little guy can move up the tree trunk. (Sorry it gets a bit blurry towards the end.)

Of course, as we’ve moved in to the colder temperatures and inclement weather of winter, we don’t see hoverfly larva out and about so much. But, as I found yesterday, if you pick up a handful of leaf litter and riffle through it, you can still find these larvae. I’m not sure how long this little creature will remain in its larval state before pupating – I think that depends to some degree on species – but it was certainly a nice reward for getting my fingers mucky.

Hiding in plain sight

7-spot ladybird, British ladybirds, ladybird, ladybirds in winter

Have you ever wondered where ladybirds go in winter? Some of them hide away in crevices in tree bark, or under unused flower pots in garden sheds; some even invade our houses, where they can often be found huddled together along the edges of windows.

Others can be spotted outside, hiding in plain sight, as you see here, tucked in holes in fences or clinging on beneath seed heads. They’re such wonderful, though tiny pops of colour in an otherwise fairly drab landscape.

Out they pop

Invertebrates in the winter: some warm sunshine in a sheltered spot and out they pop: my first hoverflies of the year, several species of fly, a couple of Honey bees and a queen Buff-tailed bumblebee.
I should probably add that these images were taken on Sunday, before freezing Baltic air came blasting in from the east, causing temperatures to plummet. I imagine these critters have all now taken shelter once more, in amongst dense vegetation like Ivy or within cosy holes in the earth.

Viburnum cushion scale

A couple of days ago I brought home two Ivy leaves I’d plucked off a plant on my way home (I’m trying to improve my sketching skills this year and figured these might be an easy leaf to start with). It was only when I got home and was looking more closely at them that I discovered one leaf had some tiny attachments on the underside.

These are Viburnum cushion scale insects (Lichtensia viburni), which, in southern Europe, are recognised as pests on Olive trees, while, in northern Europe, they are mostly found on Ivy. From looking at photos on the Bladmineerders website, the scale insects I found are male. Beneath their outer shield, they will eventually moult into two-winged adults and fly off to find females to mate with.

The female scales are the ones some of you may have noticed on your plants – once fertilised in the springtime, their bodies swell with eggs and produce a white woolly covering, which is actually the egg sac. You can read more and see further images on the Bladmineerders website.

This is how they do it (*wink*) …

As happens every year, I found many invertebrates I’ve not been able to identify, especially from riffling through the leaf litter. Perhaps one of you will recognise one of these creatures but, even if you don’t, I feel they deserve their moment in the spotlight.

R is for Ruddy darter

British dragonflies, dragonfly, Odonata, Ruddy darter, Sympetrum sanguineum

2023 was a good year for me for odonata. On 26 June, just five days after seeing my first Small red-eyed damselflies, I found my first ever Ruddy darter (Sympetrum sanguineum), though this was a female so did not look at all like her ‘ruddy’ name. My 30 June blog, Lifer: Ruddy darter, tells the story, and I already have a note in my 2024 schedule to look for more of these at the country park near this year’s find spot.

N is for new and noticed

Bombylius canescens, British insects, Eurygaster testudinaria, Mystacides azurea, Nematus lucidus, Nowickia ferox, Ribautiana tenerrima, Typhlocyba quercus

I’m using the letter N to highlight a few of the new insects I’ve been lucky enough to find during my 2023 meanderings. First up, in early spring, was a new fly species, the torpedo-shaped Nematus lucidus (below left) and then, in July, another, the bristly brute that is Nowickia ferox (below right).

231219 1 Nematus lucidus Nowickia ferox

Next up, a new bee-fly. We usually only see Dark-edged bee-flies (Bombylius major) in my part of south Wales so it was super to spot this Western bee-fly (Bombylius canescens) during a visit to Aberbargoed in mid June.

231219 1 Bombylius canescens

On 17 July, in my local ‘secret field’, I discovered the final instar of a new shieldbug, Eurygaster testudinaria (left), and, the following day, I had another new find, the pretty caddisfly, Mystacides azurea (right). I didn’t blog this little creature at the time as I wasn’t sure of my identification but you can read more about it on the Nature Spot website.

231219 3 eurygaster testudinaria Mystacides azurea

Last, but certainly not least as these are favourites of mine, are two new leafhopper species. The seventeenth of July was a red letter day, with two new species found in my ‘secret field’, both the shieldbug mentioned above and, perched on an Oak leaf, the vibrant little leafhopper Typhlocyba quercus (left). I’ll certainly be checking for more of these next summer. Then, in the middle of November, bopping around a Bramble bush in one of the local cemeteries, I spotted the beautifully patterned Ribautiana tenerrima (right), and was left wondering how I’d never seen them before. I’m already looking forward to what new invertebrate species 2024 will bring.

With their intricate patterns and superb colour combinations, I think it’s true to say that moths are amazing! To showcase how visually stunning they are, I’ve pulled together a slideshow of some of the moths, and their larvae, I’ve encountered during 2023. Enjoy!

L is for leafminers

British leafminers, leaf-mining fly larvae, leaf-mining moth larvae, leafminers, leafmines, leafmines on plants, leafmines on trees

As a result of standing staring for hours at leaves, I’ve found lots and lots of lovely new-to-me leafminers this year. Here’s a summary of those I’ve blogged about:

On 13 February, Leafmines: Phyllonorycter ulicicolella covered the tricky-to-find mines of tiny moth larvae on gorse. In Leafmines: Eriocrania unimaculella, 22 May, the larvae of a different moth were mining Birch leaves, and, on 26 June, Leafmines: Mompha terminella, featured more moth larvae mines, this time on Enchanter’s nightshade. In October the moth miners were munching on Hawthorn leaves (Leafmines: Bucculatrix bechsteinella, 2 October) and on Blackthorn (Leafmines: Lyonetia prunifoliella, 9 October). The only new non-moth miner of the year was a fly whose larvae were found mining the leaves of Alder (Leafmines: Agromyza alnivora, 16 October) and, later in October, we were back to moth miners, with Hawthorn once again the plant of choice (Leafmines: Phyllonorycter corylifoliella, 23 October). In November, a willow moth miner I’d mentioned once before in passing starred in its very own blog (Leafmines: Phyllonorycter viminiella, 20 November) and, a week later, on 27 November, another moth larva was found on the leaves of a rose species (Leafmines: Stigmella anomalella). The final leafminer find of 2023 was yet another moth, this time devouring the leaves of Wild privet (Leafmines: Gracillaria syringella, 4 December).

I’ve already referenced the three case-bearing moth larvae leafminers in an earlier countdown blog (C is for Coleophora) but, just for completeness, I’ll also link to them here: Leafmines: Coleophora lutipennella on 1 May, Leafmines: Coleophora serratella on 15 May, and Leafmines: Coleophora gryphipennella on 13 November.
