Very happy to have contributed to the article by Jack Supple. https://www.cell.com/current-biology/abstract/S0960-9822(25)01544-123 Dec 2025 09:13 +0000at://did:plc:bfnb4gx6k3zzhui3maln37my/app.bsky.feed.post/3manfv23iws2jhttps://bsky.app/profile/gregoeur.bsky.social/post/3m36clghvp223Olive quick decline syndrome is a disaster happening right now. We investigate the insect vector using anatomy, single cell recordings and behavior. The spittlebug is a trichromat, attracted to polarized light, which might be useful in trapping. https://onlinelibrary.wiley.com/doi/10.1111/aab.7006514 Oct 2025 17:58 +0000at://did:plc:bfnb4gx6k3zzhui3maln37my/app.bsky.feed.post/3m36clghvp223https://bsky.app/profile/gregoeur.bsky.social/post/3m2t7xrm3ic2mHow cool is it to place three moths under an IR USB microscope and monitor their pupil across days, at different temperatures? https://link.springer.com/article/10.1007/s00359-025-01759-010 Oct 2025 08:12 +0000at://did:plc:bfnb4gx6k3zzhui3maln37my/app.bsky.feed.post/3m2t7xrm3ic2mhttps://bsky.app/profile/gregoeur.bsky.social/post/3lzqao26vsc2fIt turns out that many Nymphalid butterflies have a colorama screen filter embedded in their eyes. https://link.springer.com/article/10.1007/s00359-025-01761-626 Sep 2025 10:22 +0000at://did:plc:bfnb4gx6k3zzhui3maln37my/app.bsky.feed.post/3lzqao26vsc2fhttps://bsky.app/profile/gregoeur.bsky.social/post/3lrcyreewp22vThis is what the high meadows (mt. Olympus in the back) look like if there are red-loving beetles around! We revisit the 2012 study on Glaphyridae (https://link.springer.com/article/10.1007/s00359-012-0722-5) and reveal the basis for their visual preferences. https://journals.biologists.com/jeb/article/doi/10.1242/jeb.250181/368218/Remarkable-red-colour-vision-in-two-Mediterranean11 Jun 2025 08:34 +0000at://did:plc:bfnb4gx6k3zzhui3maln37my/app.bsky.feed.post/3lrcyreewp22v
