Brindled Green: Dryobotodes eremita

Dryobotodes refers to feeding on oak and ‘eremita’ to the hermit-like behaviour of the larvae which isolate themselves inside developing oak buds

No. Agriopis is a very different taxonomic branch (Geometridae v Noctuidae). As different, say, as Cyprinidae v Salmonidae.

Griposia is considered a sub-genus of Dichonia - and Merveille du Jour is known alternatively as Dichonia aprilina.

Looks like ChatGpt is partially correct - as is often the case :)

Agriopis is a different group of moths among the geometrids (eg Dotted Border) - so a different family.

We’ve discovered that students and others using ChatGpt can be misled - for example by its tendency to invent references

The alternative name for the genus - Dichonia - is about hindwing pattern (= two white lines), so this whole name would be colour related.

Not sure of the meaning of ‘Griposia’

Merveille du Jour: the first of the autumn.

Griposia aprilina - referring to the ‘April green’ colour even though this is an autumn moth

Last week we visited the #freshwater #LongTermExperiment #LTE site Llyn Brianne in #Wales & met with @steveormerod.bsky.social from Cardiff University & @maplebay.bsky.social so it could be filmed for a #VirtualReality #VR experience!

Two white men are looking away from the camera as the man on the left gestures. A white man and a white woman are on the left of the flux chamber on a lake.

Centre-barred by far the commonest of the Sallows here - probably reflecting the Ash we have around and beyond the garden

I’ve only had 4 previously - the last in early September 2024. Glam Moths and Atlas suggest it’s widespread…

And I guess - as a large moth with capacity for migration - it has strong dispersal traits?

Steve Ormerod @steveormerod.bsky.social · 12d
Yes: rapid and intriguing. Most obvious explanation is climate - but if so, why hasn’t the change been more incremental at an expanding ‘edge of range’? Any insights @richardfoxbc.bsky.social?

The 2nd Clifden Nonpareil for the Cardiff garden - last caught 8/9/23. The expansion in range and numbers looks rapid: not even indexed in Glam Moths (2014). Bluesky had 33 UK mentions in the last 7 days alone on walls, attics and traps including Bridgend and Whitby

UK is well on course for losing Willow Tit, Spotted Flycatcher & Wood Warbler as breeding species in our lifetime. Wood Warbler already virtually gone from England. I think Willow Tit would be first extinction of a resident bird since Capercaillie in 1700s or White-tailed Eagle in 1918. #ornithology

3. The Woodland indicator has shown worrying recent short-term declines, but shows signs of stabilising. Favourable climatic conditions may explain this, favouring species like Blackcap. Nightingale too is shows a recent increase. But Willow Tit and migrants like Spotted Flycatcher are in decline.
Adpated image from the Defra official statistics for specialist woodland birds showing the long-term changes in percentage change - 1970-2023 on the left and short term changes (2018-2023) on the right. Species are ordered by the value of the long term change, with the largest declines at the top (in red/orange) to largest increases in green/blue). Species with no detectable change are in grey. Willow Tit and Wood Warbler are highlighted as species in trouble, Nightingale as species which have experienced big long term declines are showing some signs of improvement and Chiffchaff as a species with huge increases over both time periods
