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

Arctic plants, ichthyosaurs and more! We received funding from Nordforsk for a Nordic network for convergent evolution #NCEN! It is led by @siribirkeland.bsky.social and me, hosted at the Natural History Museum @uio.no and include researchers with amazing work🥳 www.nordforsk.org/projects/nor...

Excited to soon start my new role as Academy of Finland Research Fellow 🦋🐛I’ll later be advertising a PhD position on tiger moth colour and genomics, and will be speaking at #ESEB2025 this week if you want an idea of what’s going on!

Happy to play a small role in this nice paper, and hope to visit this region one day!

✴️ NEW PAPER! ✴️ In the beautiful Caucasian mountains of 🇬🇪 lives a moth whose wing colour variation (🔴🟠🟡) has intrigued us for ages. Here (doi.org/10.1111/1744...), we studied whether such variation is associated with 🧬 structure or other traits such as size. (1/3)

Interested in a PhD connecting sensory ecology and evolutionary genetics? Applications are now open for a project on the Speciation Genomics of Eye Size Variation in Heliconius Butterflies in our lab at LMU Munich: www.evol.bio.lmu.de/research/mer... Please repost!

🚨New paper on tropical moth pollination 🧵1/8 - What happens in tropical ecosystems when the day ends?🌔🦋 Our new review that @robtrop.bsky.social and I wrote highlights moths’ vital role in pollination and outlines research gaps, challenges and biases. Sharing valued! Link: doi.org/10.1017/S026...

Lovely to be back in Sheffield for the Population Genetics group conference. First day full of colour, butterflies and tea #pgg58

🧪Why does warning signal variability persist in #aposematic species? Our new @sse-evolution.bsky.social paper explores this using data from 64,741 🤯 A.plantaginis, raised over 25 generations. Spoiler: no evidence that life-history traits constrain warning colours! academic.oup.com/evolut/advan...

Evolutionary potential and constraints in an aposematic species: Genetic correlations between warning coloration and fitness components in wood tiger moths

Abstract. Variability in warning signals is common but remains puzzling since deviations from the most common form should result in a higher number of pred
