🚨New paper🚨 Garden #spiders are everywhere right now—big, beautiful ladies, still in the hub of their 🕸️ But they are not just waiting, at night they also 💤! We found behavioral signatures of sleep in the wild. Out in #AnimalBehaviour w/ @mherberstein.bsky.social tinyurl.com/uznvv58y 🧵1/5

Adult female garden spider (Araneus diadematus) sitting at the center of her orb web, with orange‑brown legs and a patterned abdomen. The web’s radial and spiral threads are sharply visible, catching the light. The background is blurred green foliage with soft circular highlights, making the spider and web stand out in clear focus.

A little video of us setting up the #cameras to film #spiders in a #cave. What a fun alternative to sitting at the desk in 34 degrees! Refreshing 6 degrees (Celsius) inside the cave! 🙃

Very excited to share our discovery of an engineering masterpiece from the Australian rainforest! In our latest paper in @currentbiology.bsky.social we report a hunting strategy in a spider, whose web outperforms every known biological catapult system.

Off to the caves! We’re finally back in the field: filming sleepy cave spiders! 🕷️🕸️ Let’s see what we find! #fieldwork #animalsleep #caves @roald-arboel.com @nadjageiger.bsky.social @roesslerdaniela.bsky.social @unibonn.bsky.social

New paper alert!🕷️✨ Tiny spider. Shiny abdomen. Suspiciously wiggly bum. In our new study, we asked what abdomen bobbing in this jumping spider is really all about: Cute? Yes. Meaningful? Let’s find out...! [1/8] @unibonn.bsky.social link.springer.com/article/10.1007/s00265-026-03745-1

🚨 TWERK ALERT 🚨 New publication from @sleeblab.bsky.social ! This was a very fun project to write up, co-lead by @nadjageiger.bsky.social and Chiara Hirschkorn. If you are interested why these spiders might bob their abdomen: link.springer.com/article/10.1... (Short thread following soon)

Congratulations @rochellemeah.bsky.social @ecologyofvision.bsky.social (and all our wonderful coauthors!) on her first PhD publication in @currentbiology.bsky.social 🤩 Light pollution suppresses natural peaks in activity AND natural celestial polarization patterns at key times in arthropods 🕷️🦋✨

🎬 That’s a wrap! 🥹 after a bumpy last week off grid together with the fabulous @vanspidergirl.bsky.social & @madmetazoa.bsky.social we successfully finished an incredible field season on #portia and #invertsleep in the oldest rainforest of the world. Nothing but grateful for this experience ❤️

Things that can happen while filming Portia in the field: we had a (not so) little visitor wandering by with his chicks! Not sure who was more surprised… #cassowary #portia #daintree #storiesfromthefield

Rain and cameras are not best friends - @nadjageiger.bsky.social and I are doing our best to keep them dry and rolling all night despite - or because of - the rain #haaaaard #camerashaterain

We love behaviors that are usually hidden- often due to the sheer fact that they are hard to observe-like sleep. But we’ve also been wondering about things like: what do these spiders do (and how do they sleep) in heavy tropical rain?? We are determined to find out! #portia #fieldfun #RAINforest

Meet an outrageously cool jumping spider (maybe not as cool as Portia but still pretty badass): Bavia! As you can see, she also likes a good spider snack around bedtime. Not sure if she was able to finish this one. She already looked pretty stuffed 😬

It’s experiment time! While doing things in the field always adds an extra layer of difficulty (and also frustration), it is very rewarding once it works! #mosquitos #rain #stillhappy

@nadjageiger.bsky.social & @roesslerdaniela.bsky.social are back in the field in Australia filming and experimenting with the best spider in the world - PORTIA. More soon!
