Back in September 2017, I wrote a blog about the experience of seeing a female Garganey on Roath Park Lake (Autumn migration: Garganey).

Roll forward seven years to last Tuesday, 27 August, and my trip to north Cardiff was almost an exact repeat of that day in 2017: searching but not initially finding the bird; going for a walk and trying again (though this time I had some help from a local birder who’d seen the Garganey earlier that morning); noting how she was feeding so frequently amongst the lake weed that most of my photos were of a headless duck.

As with so many duck species, the female Garganey (Anas querquedula) does not have the showy plumage of the male of the species but this was a gorgeous, very dainty little duck. And, once I did eventually find her, she was a joy to watch.

Leafmines: Caloptilia stigmatella

Another Monday, another new leaf mine – they’re never ending!

240902 Caloptilia stigmatella (1)

Now, this may not look like a mine but what’s happened is this: once hatched from its egg, the larva chewed an initial linear mine in the surface on the underside of the leaf – this species uses willow (Salix sp.) and poplar (Populus sp.). Then it munched out a blotch at the edge of the leaf and rolled the edge over to create a cone. As you see here, the larva will often create two or even three cones before it pupates.

240902 Caloptilia stigmatella (2)

These mines and cones are the work of the moth Caloptilia stigmatella. You can see more examples of the mines and get more information on the British Leafminers website here, and see photos of the adult of the species on the UK Moths website here.

The first of Autumn

Though today was actually quite warm and humid, there’s no denying that autumnal feel in the air. The evenings are getting dark earlier; there’s an occasional hint of a heavy dew, if not quite a frost; the birds have already begun their migration south for the winter; and, on the trees and shrubs, the fruits are bright and bursting, the leaves beginning to turn. Happy Autumn to all in the northern hemisphere (and happy Spring to those down under)!

Alder spittlebug

“High five!”

240831 Aphrophora alni Alder spittlebug (1)

The Alder spittlebug (Aphrophora alni) is very similar to the Common froghopper (Philaenus spumarius), and I have a feeling I may have mistaken them in the past, as this was the first time I was certain this was the spittlebug. The British Bugs website explains that ‘The genus can be recognised by the keel running down the midline of the head and pronotum, and the species by the colour pattern with distinct white patches near the margin of the wings’. To my eye, the spittlebug is a noticeably bigger – the froghopper is 5-7mm long, the spittlebug is 9-10mm – and wider in the beam.

Cordyceps fungus

It was tiny and, at first glance, I thought it was one of those madly shaped egg sacks created by sputnik spiders (see The sputnik spider, 6 July 2017), but no. This is my first ever Cordyceps fungus, which is erupting from the body of an insect.

240830 cordyceps fungus (2)

In his publication Fascinated by Fungi, author Pat O’Reilly explains: ‘The Cordyceps mycelium colonises the living insect and mummifies it, keeping it alive just long enough to generate the biomass necessary to produce another Cordyceps … fruitbody.’ I discovered a very similar example to my find, with an excellent detailed explanation of the process, on the Project Noah website here.

Juvenile Tufted duck

Tufted ducklings are still quite a rare sight in the Vale of Glamorgan, though breeding records have increased in recent years – three broods have been recorded in Cardiff Bay this year, for example. Today’s little bundle of now-partial fluffiness, however, was raised, along with its five siblings, at The Knap in Barry, where I caught up with it on Monday when I went to see the Grey phalarope. The Knap is a very shallow, man-made lake, in a heavily managed park, so it’s not easy to see where the nest was – perhaps beneath some thick shrubs and bushes with a stone wall behind. Still, mother Tufted duck has done very well indeed to raise six ducklings in such a setting.

Aleiodes mummy wasp

I found this remarkable but tiny object a couple of weeks ago when checking out some Buff-tip moth caterpillars on a small willow tree, but I’ve delayed posting about it until I had confirmation of identification.

240828 aleiodes (2)

The situation is this: a female Aleiodes wasp (species unknown) laid her egg in a caterpillar (species also unknown). When the egg hatched, it fed inside the caterpillar, eventually leaving the skin of the caterpillar hardened, in a state many people describe as a ‘mummy’, which is why the Aleiodes wasps are commonly referred to as mummy wasps. The wasp larva pupates inside the mummy, and will eventually bite a hole in the outer skin to emerge as an adult. As I was intrigued to see what might emerge, I’ve brought this mummy home, and it’s currently in a jar on my kitchen window. If/when something emerges, I’ll post about it.

240828 aleiodes (1)

There’s an image on Bug Guide website that looks quite similar to the mummy I found, and another on Jungle Dragon, where you can see the exit hole made by the adult wasp (or wasps) when it/they emerged from pupation.

Juvenile Grey phalarope

Storms can be destructive, terrifying, and costly but, sometimes, they can also be bountiful. We were lucky here in south Wales to avoid much of the severe weather from last week’s eleventh named storm of the year, Storm Lilian, but we have had very strong westerlies for several days and, on Sunday, they brought local birders a stunning avian gift in the form of this juvenile Grey phalarope.

240827 grey phalarope (1)

And, even better for low-carbon birders like me, this little charmer was very accessible, spending its time on a man-made lake at The Knap in the seaside town of Barry. For me, this was just a walk, a train ride and a second walk away, so I went to see it yesterday morning, a Bank holiday Monday here.

240827 grey phalarope (5)

The Grey phalarope (Phalaropus fulicarius) breeds in the Arctic and, at this time of year, is beginning its migration south to the tropical seas where it over-winters. And during its migration, between September and December, is typically when birds like our little visitor are blown inland by storms.

240827 grey phalarope (2)

They are stunning birds to watch, as they have quite an unusual method of feeding, constantly spinning left and right and sometimes round and round, as they pick tiny invertebrates from the water. Watching this one almost made me feel giddy, and also made it difficult to photograph as it was never still.

240827 grey phalarope (4)

On the positive side though, Grey phalaropes are often very confiding and this little beauty was certainly that, paying absolutely no heed to its many admirers, and coming to within a foot or so of the birders and locals watching it from the lake edge. Such a treat!

Leafmines: Cephalomyza labiatarum

Since I read earlier in the year about the larvae of one of the case-bearing moths living on Hedge woundwort (Stachys sylvatica), I’ve been checking those plants whenever I see them. I’ve not yet found the Coleophora species but, a week or so ago, I did find some leafmines I’d never seen before. These are the larval mines of the fly Cephalomyza (formerly Amauromyza) labiatarum and they can, in fact, be found on a very wide range of plants (the Agromyzidae Recording Scheme website lists the following species: Ajuga, Ballota, Galeopsis, Glechoma, Lallemantia, Lamiastrum, Lamium, Leonurus, Lycopsis, Marrubiam, Melissa, Mentha, Prunella, Satureja, Scutellaris, Stachys, Teucrium, and Verbena). As you can hopefully see from my photos, the larva’s initial feeding creates a long thin line, which later becomes a large blotch mine. You can see more images on the Agromyzidae RS site referenced above and on the British Leafminers website.

Prickly lettuce

British wildflowers, Lactuca serriola, Prickly lettuce

I saw someone mention this plant on social media, looked it up and thought why haven’t I seen that, and the very next day there it was, growing amongst a riot of wildflowers and grasses alongside a smelly brook in a Cardiff park. This is Prickly lettuce (Lactuca serriola).

240825 prickly lettuce (1)

It’s described on the Naturespot website as:

Tall, greyish, stiff and erect plant to 1.8 metres. Stem sometimes bristly. Leaves alternate, oblong, prickly on margins and along the mid-rib beneath, sometimes irregularly lobed, clasping the stem with arrow shaped points. … Flowerheads pale yellow 11 to 13 mm numerous, in a narrow pyramidal panicle.

240825 prickly lettuce (2)

I wasn’t one hundred percent sure of my identification until I turned over a leaf to follow the leafhopper that had disappeared beneath and spotted that vicious-looking row of spines along the mid-rib (though they weren’t actually as vicious as they looked).
