Introducing the crew to German carnival with funky #DYI #jellyfish group costumes @unibonn.bsky.social @roald-arboel.com @mchagourin.bsky.social

What does the evidence actually tell us about insect sentience?

Join us on March 11 as @viveknityananda.bsky.social examines frameworks for investigating insect welfare, including key debates around insect emotions and pain.

Come hear me stir up some controversy* next month with my take on the evidence for insect sentience.

*or not, depending on your point of view.

Awesome!!!

🤣 I don’t think it’s a real term (yet) but we kept seeing them “cribellating” (making cribellate silk) in the field and it was just the best way to describe them :)

🕸️ Massive web stretch from our cribellating friend (Asianopis subrufa) recorded in the field. If you’re intrigued by this fabulous #spider #silk read on doi.org/10.1073/pnas.2529200123 by @evoimec.bsky.social et al :) 🕸️

🕸️ The #silk of this gorgeous little cribellator is not your standard silk - read @evoimec.bsky.social new study here: doi.org/10.1073/pnas... 🕸️

🚨 🕷️ 🕸️ You thought netcasting spiders could not get any cooler?! You were wrong! Check out this new study lead by @wolffspider.bsky.social @evoimec.bsky.social showing how these spiders behaviorally tune their silk to be hyperelastic AND super load-bearing www.pnas.org/doi/full/10....

Field emission scanning elactron microcopy image showing the microscopic structure of a lower web radius of the Australian netcaster (Asianopis subrufa). The thread contains two separate strands, each of which is made of a soft silk core with fine loops of nanofibres attached to it. Upon extension, the thread initially behaves like a soft elastomer, but as soon as the fibre loops straighten they add to the load resistance of the thread, causing a mixed mechanical profile that combines elasticity with strength.

The special thread meta-structure of the hyperextensible web radii is a looped-fibre reinforced elastomer - seen in all its beauty in this image - which just won the Royal Society Photo Competition! royalsociety.org/journals/pub...

Figure showing a video still from a high speed video of a netcasting spider capturing a cricket with its elastic web held in the front legs. Left to the video still there are load-strain diagrams of different lines in the web showing that the upper lines are stiff and strong and the lower lines are highly extensible. Left to the diagrams there are scanning elactron microcopy images of the dfifferent lines, showing that the upper, stiffer lines are cables made of many parallal fibres, whereas the lower lines have a soft central core with adjoined looped fibres. The degree of looping correlates with how much the spiders post-process the silk after spinning. This way they can tailor the stiffness of each line in the web separately and create a vertical stiffness gradient throughout the whole web architecture from stiff and strong in the upper load bearing frame to soft and hyper-elastic in the lower part that is rapidly extended and thrown against the prey at high speed during the predatory strike.

Netcasting spiders modulate silk thread stiffness via a tailorable multi-fibre meta-structure to construct a web that is hyperelastic and high load-bearing at the same time.

Missed our #ECBB2026 Plenary Speaker reveals? Not to worry!

Here is a quick recap of all the excellent speakers we'll be welcoming at September's meeting!

Header: ECBB 2026 Plenary Speakers Image of Dr Bibiana Rojas, University of Veterinary Medicine, Vienna Text next to photo reads: Main interests in the interface between behavioural and evolutionary ecology Aspects of communication, animal colouration, predator-prey interactions, aggression, parental care, and life history trade-offs The effects of anthropogenic activities such as habitat alteration and contamination on the life history, health and behaviour of amphibians

We know you're jumping with excitement to find out the penultimate ECBB 2026 plenary speaker so we won't keep you waiting much longer!

It's the marvellous @biobiiana.bsky.social!

Multiple anthropogenic stressors can negatively impact species but can a single stressor also have multiple, concurrent impacts? Here we show that light pollution creates several simultaneous impacts to the nocturnal movement ecology of a moth and a spider: tinyurl.com/5eku5bff (1/5)

ECBB 2026 logo above header that reads ECBB 2026 Plenary Speakers Photo includes:Prof Mariella Herberstein, Leibniz Institute for the Analysis of Biodiversity Change Text reads: - Interested in all aspects of spider behaviour – from mating behaviour and sexual cannibalism, to web-building, mimicry and deception - Behavioural ecology of various insects, including moths, bugs, damselflies, and praying mantids - The evolution of imperfect mimicry in ant-mimicking spiders, warning signals in moths and butterflies

Ready to meet our third plenary speaker? We are delighted to announce it's....

The extraordinary @mherberstein.bsky.social

'Mesmerizing spider threads' by Dr Martin J. Ramirez, captures two exceptional silk threads of the Australian net-caster spider, Asianopis subrufa.

We're excited to announce the finalists of the #RSPPhotoComp 2025! 🎉 Starting with #microimaging and overall winner, 'Mesmerizing spider threads' by Dr Martin Ramirez, capturing two exceptional silk threads of the Australian net-caster spider (sample obtained by Dr Jonas Wolff @evoimec.bsky.social).

🎬 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

🚨Good news, everyone!
1) I'm thrilled to be joining the behavior powerhouse that is Indiana University!! So stoked, starting Jan 2026.
2) I'm recruiting grad students! Are you (or your trainee) interested in sensory ecology? behavior? evolution? fieldwork? spiders? Drop me a line Jstafstr(at)iu.edu

Omg! Amazing!!!!!!!!!!!!!! Congrats Jay!

🚨 Uh-oh!!! A suuuper hot #PhD opportunity just dropped! My friend and collaborator Massimo De Agrò is looking for someone to explore jumping spider vision and neurophysiology! #psychophysics #jumpingspiders #greatPI - apply!!!! (Deadline December 17th) 🚨

🥲🙏🏻

Incredibly honored and utterly excited to have been asked to give a plenary at @isbe2026.bsky.social hope to see you in Turin! #ISBE2026 #sleep #behavior
