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
🎨 job alert 🐠 Come join us! We have two positions open! These are part of our @erc.europa.eu funded project on the mechanisms underpinning convergence of colour patterns in cichlid fishes! Closing date: 16th August. Postdoc: www.cam.ac.uk/jobs/researc... Technician: www.cam.ac.uk/jobs/researc...

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.
So grateful I can study and work in such a wonderful and safe environment as we have in Helsinki. Share the love for diversity and happy #pride 🏳️🌈🏳️⚧️
Nature is wonderfully diverse—and so are people. 🌈 As evolutionary biologists, we know that diversity is one of nature's greatest strengths. Happy #Pride from the Wood Tiger Moth Lab! 🐛🏳️🌈 @aplantaginis.bsky.social @helsinki.fi
🏳️🌈 Happy Pride Month! Mindful that biology has been weaponized against the LGBTQ community by people who don’t know much about biology, I’m making daily, queer, biologically themed posts for #PrideMonth2026 6/19: The bacteria named Wolbachia turns boy butterflies into girl butterflies
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.
Reminder that to see the world as one giant, living web, one must go outside. So excited that the summer field season is now in full swing.
A few summers ago, we individually reared 1200 wood tiger moth caterpillars with the aim to understand the associations and genetic basis of different traits; colour, chemical defences, behaviour, pheromones and more. The results are here!
Independent major-effect loci and limited trait associations characterise warning colour variation across sexes and life stages in the wood tiger moth (Arctia plantaginis) https://www.biorxiv.org/content/10.64898/2026.06.03.729769v1
The groups first field trip is underway! @paulinea73.bsky.social got the first caterpillar of her PhD 🥳 @michalbartak.bsky.social
One of my PhD chapters is now out! It’s a review on pyrazines in insects and their biological roles and their evolution. onlinelibrary.wiley.com/doi/10.1002/... @lepphylo.bsky.social @jmappes.bsky.social
Ecology and evolution of pyrazines in insects

Amazing time at the 35th LUOVA Spring Symposium held in Viikki @helsinki.fi, organised by PhD researchers. Grateful to this year’s keynote speakers @ricardonature.bsky.social, @profkathrynelmer.bsky.social, and Marco Gamba for their talks, insights, and engagement with the community of PhDs.
New preprint! “Climate-driven specialisation in plant–pollinator networks peaks outside the tropics” Testing the long-debated latitudinal specialisation gradient using >3,400 quantitative networks (>110,000 interactions). Led by @saileesakhalkar.bsky.social and myself ☺️ doi.org/10.1101/2025...

With Pride Month🏳️🌈 at its peak, it’s a good time to revisit this powerful piece by Kamran & Jennings (2023): fieldwork must be made inclusive and safe by recognising differences, rethinking planning, protocols, and hearing LGBTQ+ voices. Safety is inclusion. #PrideInSTEM 🔗 doi.org/10.1093/icb/...

Grateful for the opportunity to present our very recently accepted review paper on Nocturnal Moths as Pollinators in the Tropics that @robtrop.bsky.social and I wrote at the #OIKOSFin2025. Stay tuned for the full paper coming soon!
Great kick-off by my team @aplantaginis.bsky.social at #OIKOSFin25! 🎉 @zowioudendijk.bsky.social shared fascinating insights on the evolution of reflex bleeding in Arctiinae, and @theobrown.bsky.social made a compelling case for 'why to pay to be lazy'(—if you’re a toxic butterfly!) 🦋🔥
Excited to kick off my PhD at the @helsinki.fi with a talk about my doctoral research plans at the 34th LUOVA Spring Symposium
