Leaving aside the emotive overtones, nocturnal moths don't have visual cues, so all kinds of signals may help?

Canary-shouldered Thorn. I can't rationalise it, but somehow this picture reminds me of Willie Whitelaw.

Some days I wake up and I really find myself yearning for the sort of stimulating discourse you can only find on X.

Apollo (Parnassius apollo), Β© Jon Dunn

A butterfly with baubles on its wings! For day 6 of the Mariposa #AdventCalendar, bringing a daily dose of colour and joy to your timelines, the mighty Apollo. We see this enormous insect on many of our mountain tours in the Alps, Pyrenees & Picos de Europa. Every encounter as special as the last.

Kemi Badenoch, who has been in the job for five minutes, refused to announce any policies, and fluffed every single PMQs she's taken part in, is named the Spectator's "Leader of the Year".

I of course understand the opposite - that the left wants Macron to own the mess he largely triggered

But in the end politics still impacts people’s lives. Budgetary decisions have to be taken. So on balance I hope the left (or a part of it) seeks a way to govern short term

Living up to its name...December Moth; came to light on 1/12. I know it's common, but it is handsome and so very hairy and well insulated. A welcome end to the year's mothing.

Also a big decline in UK. Became extinct in my home county of Dorset in 1980s, but still doing OK in a few well managed woods and bracken slopes in north and west

Very very unexpectedly good night for moths. 52 of 10 species in SE Hants VC11. Nothing new and only one migrant a Diamond Back. 26 Nov Moth agg, 12 Feathered Thorn (mostly puddle rescues). Most surprising was a Blastobasis adustella

Did you know? ... Looking like a beautiful FabergΓ© egg, the volume of the Scotch Argus egg relative to its wingspan is 3.1% and is the largest ratio of all of the British and Irish butterflies (the smallest ratio belongs to the Meadow Brown, which is just 0.31%).

A wooded shore is reflected in a calm lake. The fog rises from the trees and reveals a view of a mountain peak and the beginning of dawn. The sight has a calming effect, beautiful blue tones dominate the scene.

A photo of a Glanville fritillary butterfly with open wings, sitting on a marguerite between many others. The scene is photographed in the soft early morning light. The top of the butterfly is directed to the camera. The other marguerites are out of focus and more or lessed blurred.

Excellent substance from Peter Kellner this morning (kellnerp.substack.com), gives an objective demonstration that Starmer & Reeves must stop being spooked by the EU and get us back in the single market - well worth reading.

Did you know that, when it comes to the resident butterflies of Britain & Ireland ...

5 overwinter as an adult
9 as an egg
31 as a caterpillar
11 as a chrysalis
1 (Speckled Wood, πŸ“Έ below) as both a caterpillar and chrysalis?

I had to lay flat on my belly on the hard stony riverside for this shot and effect. So, the backdrop is basically all stones. As for the main subject, it's a male Odalisque damselfly (Epallage fatime) and this is the only species of the genus.

What are Donald Trump’s plans to overhaul US colleges and universities? Republican president-elect says he wants to dismantle the US education department and fire β€˜radical left accreditors’

If some of these statements that Trump made about plans for universities come off it is grave news for the sector. Targeting courses that address Dis/mis-information, measures to assess edi will be out too and accreditation for standards. πŸ§ͺ#academicsky

Good morning from Greece. Let me share some of our light & sunshine with you all...

This is a Plain Tiger (Danaus chrysippus) nectaring on Woody Fleabane (Dittrichia viscosa).

For photography/technically minded folk, this is a full frame uncropped image, shot with a telephoto lens at about 400mm.

Ecoimmunology. Fundamental discovery lab-based immunology typically focuses on defined model systemsβ€”(in vitro or in vivo models such as mice or ex vivo tissues) to understand immune programming in the context of biological processes, health, and disease. In contrast, disease ecology focuses on the role of the environment and considers population dynamics and individual variation. Whilst there is some limited overlap in disciplines, the area of ecoimmunology aims to bridge these gaps and takes a more holistic approach to understanding what shapes the immune system and thereby health.

Delighted to share our latest in @discovimmunol.bsky.social with @kathelse.bsky.social Holly Shiels, Iris Mair & Susanne Shultz. Climate change, pollution and changing land use impact immune function, driving chronic inflammatory disease and create exposure to infections (new & old). πŸ§ͺ #Immunosky

Just joined sky, having abandoned X. Just learning the ropes. Here's another splendid moth from last summer (Gypsy Moth). A pest, but a handsomely equipped one.
