This weekend, I was invited by the association A.L.L.E.E. in Toulouse to present earwigs to a broad and curious audience. It was a fantastic opportunity to share our work, highlight why fundamental research matters, and spark new appreciation for these often-misunderstood insects. 😃😃😃

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 🚆🚅🚌

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 😳

Today, a lot of earwig research was presented at the French-speaking section of the #IUSSI in Paris. Special rounds of applause to Laura Pasquier and Simon de Wever for their excellent presentations on their PhD projects.

Léo Korst finished his master's project in my group this week. Much to my surprise, he gave me a wonderful painting of an earwig. He is clearly talented in both science and art! Thank you so much Léo!

New paper out: "Alternative reproductive strategies in two cryptic species of the European earwig complex" rdcu.be/eqfpM

F. dentata invests before egg-laying, F. auricularia after. Same egg number, different trade-offs -> hidden paths to reproductive success. @irbi-tours.bsky.social

#EarwigFunFact 25 — In some orchards, earwigs are pests; in others, they’re valued as natural allies. So scientists tried moving them between orchards … with mixed success so far! 🪳🌍🧪

It was a real pleasure to talk about our recent data on the earwig microbiota at the REID meeting in Lyon, France.🐛🐜🐞🦠🔬🧪

Lots of interesting talks, many old friends, and a fantastic opportunity to meet a very promising generation of new scientists!

#EarwigFunFact 24 — Earwig mothers have a reputation for being devoted, but they’re also selective: they invest more care in high-quality offspring than in weaker ones. Tough love in the insect world! 🧪 ❤️

#EarwigFunFact 22 - European earwigs pack a stinky surprise with their defensive spray! Harmless but smelly, and watch out - it can leave a dark stain on your fingers if you handle too many (>100). This stain will take several days to disappear! 🌈👃🧪

#EarwigFunFact 21 - Altering the gut microbiota is a major issue for most animals. Not for the European earwig! Antibiotics don't faze them. Talk about resilience! 💪🌱🧪

#EarwigFunFact 18 - Even tiny amounts of pesticides can mess with an earwig's mom duties! Exposure to sublethal quantities of deltamethrin alters its expression of maternal egg care. Let's keep our gardens safe for these little helpers!

#EarwigFunFact 15 - Earwig dads don’t provide care, but they can transfer something to their offspring that influences how much care they get from their mom - subtle parental manipulation in action! 🤔🎭 #InsectBehavior #SocialEvolution

#EarwigFunFact 14 - Earwig moms prevent sibling rivalry by homogenizing their juveniles' chemical signatures. This hides paternity cues, reducing nepotistic cooperation and promoting family harmony. 🧪🤝 #InsectParenting #SocialEvolution

#EarwigFunFact 11 - European earwig moms don’t discriminate — they care for almost anything: foreign eggs, eggs of other earwig species, glass pearls, or even small objects. Unconditional maternal love in action! ❤️✨ #InsectCare #SocialEvolution
