I think this is possibly Choristoneura hebenstreitella, a scarce moth locally. A nice selection of moths (70 Species) in my VC29 Garden this morning others included Ghost moth, Dark Spectacle and Scorched Wing #teammoth

Trapping away from home in Botley Wood last night. 60/40 species. By the end I was so inundated with insects I packed up early! Best moth I found on another’s sheet was Agrotera nemoralis, a stunning crambid and uncommon. Best of rest Small Angle Shades, Choristoneura hebenstreitella, CbGP #teammoth

44/23 in Farnham Park last night. Obscure Wainscot, Leucania obsoleta. A rather smart Choristoneura hebenstreitella. Grey Birch Aethalura punctulata and a delightful Scorched Wing, Plagodis dolabraria. #teammoth

1/ 🌲🔬 New Research Alert! 🌡️🦋

#ClimateChange is reshaping forest ecosystems, and the spruce budworm (Choristoneura fumiferana), a major boreal forest defoliator, is feeling the heat! 🔥

Our latest study in PLOS Climate reveals some striking trends. 🧵👇

🌲🦋 Climate Change Fuels Pest Expansion

Climate change is driving a northward shift in spruce budworm populations, increasing reproduction in northern forests while raising winter mortality in the south.

Western Spruce Budworm Moth (Choristoneura occidentalis) is the most destructive defoliator of coniferous forests in western North America. Severe defoliation by this moth can weaken trees, making them vulnerable to bark beetle attacks.

D’autre part, au sein de ces écosystèmes, certains compétiteurs des parasites sont décimés par les traitements, et n’assurent alors plus leur rôle dans le maintien d’un équilibre relatif.

I've been pan-species listing in our Thursley garden. Here are a few highlights of the last couple of days.
panspecieslisting.com
Osmia leaiana, a small bee with orange hairs under the abdomen Choristoneura hebenstreitella, a striking little micro moth that seems to have escaped ever being listed within miles of here Another striking little micro moth, Pempelia palumbella, with patterns of metallic brown on a silver-grey background. The moth is only as long as the tip of my finger is wide. A very weird conopid fly with a white face. Myopa buccata, or the variegated spring beegrabber, waits on a flower to grab a visiting bumble bee and inject an egg. The fly larva then eats the bee, eventually killing it and emerging the next spring from the dead bee's empty abdomen.
