Hi all! 👋 So many new followers, time for a quick reintroduction! I’m a behavioural ecologist studying how social life evolved in insects. My favorite model? The European earwig and its surprising facultative family life. I love insects, but let’s be real, I’m no entomologist. 🪲
Amis Toulousains : C'est demain ! Venez nombreuses et nombreux 😄👍🐛
Je donnerais une conférence grand public sur les perce-oreilles à Toulouse.

Venez découvrir les secrets de ces petits insectes discrets, souvent mal-aimés, mais à la vie sociale fascinante.

📅 Samedi 15 nov. 2025 à 14h.

To learn more about research into the Triangle Weaver's astounding hunting technique, check out this article which includes video:

Using its web as a “tool” to store and release energy, the triangle weaver spider lunges at speeds equivalent to a human sprinting at 1,700 miles per hour.

Social relationships are powerful predictors of fitness across social animals. But *why*?

In our new @cp-trendsecolevo.bsky.social paper, we outline testable predictions for why relationship quality and quantity adaptively vary across socio-ecological contexts.

I'm on my way to Avignon to learn about the earwig research on a species that I know much less about than my favourite, F. auricularia. I'm looking forward to being there, despite the early start and multiple train connections 🚆🚅🚌

🪳 New paper out – Part II!

Our 2nd study on the hormonal regulation of maternal care in the European earwig is now out!

We show that blocking juvenile hormone synthesis with Precocene reduces egg care in post-oviposition mothers, while JH supplementation has no effect.

🪶 New paper out in Hormones and Behavior!

Parental care is fundamental in animals — but what actually triggers its onset? 🤔 We tested whether juvenile hormone could do it in the European earwig. Surprisingly… it didn’t.

Our new paper in Current Opinion in Insect Science digs into this question, highlights what we don’t know (yet), and lays out five priorities to push the field forward.

I'm on my way back from Roscoff, where I attended a two-day event organised by the CNRS for 'advanced researchers'. What a beautiful location❤️! It's a shame it's so far away — I still have a day of buses and trains ahead of me to reach Tours 😳

Very happy to see our new study on the evolution of eusociality come out in Evolution Letters! Our study is the first to experimentally manipulate the proportion of females that stay and help to simulate incipient sociality & assess fitness impact of helping. 🧵

🦗 New paper in Animal Behaviour! We tested if family life shields earwig juveniles from cadmium… spoiler: it doesn’t! 😅 But social interactions still shaped many juvenile traits. Fourth paper from @r-honorio.bsky.social's ATER project at @irbi-tours.bsky.social

Excited to share our new paper led by Jake Martin (@jake-m-martin.bsky.social) out in ES&T Letters! We show that behavioral ecotox studies often test pharmaceuticals at concentrations much higher than those found in nature!

It's interesting how this article, which is supposed to feature our recent paper, is wrong in every respect, from the IA-generated illustration to the (probably) IA-generated content. Too bad 😞
