Woohoo, it's now live! We show, using four lines of evidence, that butterfly wings can create illusory motion effects! @esbriolat.bsky.social, @scienceanna.bsky.social, @lauraakelley.bsky.social, @jtroscianko.bsky.social www.nature.com/articles/s41...

New study published in @natecoevo.nature.com ! We assembled the largest global dataset of plant–pollinator networks to ask a simple question: do interactions become more specialised towards the tropics? doi.org/10.1038/s415... Study led by @saileesakhalkar.bsky.social and myself ☺️ 1/8

Insects are increasingly pressured by climate change. Here the authors compile global evidence of range shifts in butterflies and call for more co-ordinated efforts in documenting such trends across countries 🧪 www.nature.com/articles/s41...

A great week at #ISBE2026 in Turin! 🇮🇹 EEI was well represented with @eselenius.bsky.social talking about sexual selection, @michalbartak.bsky.social presenting his first chapter on the effect of photoperiod of life-history and @theobrown.bsky.social discussing why butterflies fly slowly!

When to feed as a caterpillar? Is the activity timing internally controlled or plastic? I’ll present some of our recent behavioural research at the Uni of @helsinki.fi from the @aplantaginis.bsky.social lab at the #ISBE2026 in Torino. 📍Thursday 23 Jul at 12:00, Room Londra @isbe2026.bsky.social

Our @aplantaginis.bsky.social 🦋 fieldwork season is in full swing — this time we’re in Finnish #Lapland 🦟 No night at all here at this time of the year, only a few hours of twilight with the midnight sun ☀️ Also genuinely concerned about the number of lupines here.

In awe of the tremendous diversity of Bulgarian #Lepidoptera we saw and collected to generate reference genomes for @projectpsyche.bsky.social during the @10klepgenomes.bsky.social field workshop, where genomicists, taxonomists, and all Lepidoptera enthusiasts met under one roof.
