Schaut Euch mal das irre Spinnennetz im Bild rechts oben genau an. Das ist ja der absolute Wahnsinn😮🤩

New publication! 🕷️ In the Analamazaotra National Park, Madagascar, we investigated how kleptoparasitic spiders choose host webs. The answer isn’t random! Which web to invade? Argyrodine kleptoparasites differentiate amongst architecturally different host webs. bdj.pensoft.net/article/1721...

Check out our new paper! Not only do we describe a cool spider (new genus) from Madagascar, related to an Australian one, but we also make a deep dive into orb weaver morphology to better understand family relationships and synapomorhpies. Proud of this one!

Extreme Silk Toughness in Caerostris Spiders Is Limited to Adult Females - Gregorič - Integrative Zoology - Wiley Online Library onlinelibrary.wiley.com/doi/10.1111/...

New paper on bark spiders, who build the largest webs made out of the toughest silk. We show that their extremely tough silk, which is potentially metabolically costly, is limited to large females. Juveniles and males use inferior silk.

New publication! Orb weavers evolved some of the toughest silk, reaching extremes in bark spiders, genus Caerostris. We investigate sex and stage specific patterns in silk properties and find that extremely tough silk is limited to adult females. www.ezlab.si/post/extreme...

New study from @michellebeyer.bsky.social published in Animal Behaviour: Silk of females performing maternal care elicits reduced courtship responses in male spiders.

Here comes Carolina's first paper on the effects of winter temperatures on survival, physiology and gene expression in wasp spiders. Thanks go to all coauthors for their various contribution that made this work possible!🧪🕷 onlinelibrary.wiley.com/doi/10.1002/... #climatechange

🚨🚨Job! 🚨🚨Permanent (75% time) job! We are a pretty awesome research group & seek a manager who deals with everything: personnel tasks, organizing retreats, preparing code for teaching / data structures for research... Fluency in German & English essential. stellenboerse.uni-mainz.de#/jgu/job/51527

Our journal congratulates @ortizmovliavc.bsky.social l for her award at @35theca2025.bsky.social ! Her work, “Winter warming increases metabolic stress and mortality in an overwintering spider,” got her a free publication in a @pensoft.net journal. zookeys.pensoft.net/news/993

Okay, I warned you yesterday but SPIDER POST SPIDER POST SPIDER POST. Look. Spiders are great! They're our friends. They do good work out there and in our houses. I love spiders and how can you not love THIS spider, who is both a work of art *and* wildly successful at this game of hide-and-seek?

In a new publication, we focused on the little-known African spider Megaraneus gabonensis, in which females are 4x larger than males. We provide an overdue taxonomic description, phylogenetic placement, and reconstruct the evolution of sexual size dimorphism. www.ezlab.si/post/taxonom...

In a new review, we dig deep into possible explanations of the evolution of female cannibalism in spiders and various male strategies to mitigate it. www.ezlab.si/post/female-...

Spiders have personalities—and in Pisaura mirabilis, opposites might attract: adventurous males and cautious females mate longer, revealing hidden personality-driven patterns in romance. Lead by @cristinatuni.bsky.social Read more here: link.springer.com/article/10.1...

Why do female spiders eat their mates, and how do males fight back? 🕷️ Our new review unpacks the evolutionary dynamics of sexual cannibalism and the astonishing male strategies it has shaped — from nuptial gifts to remote copulation. Open access in Integrative Zoology 👉 doi.org/10.1111/1749...

We - EZ lab @ezlab.bsky.social (past/current) - presented our latest research at the European congress of arachnology @35theca2025.bsky.social . @matjazgregoric.bsky.social

New research on spider personalities, led by Cristina Tuni. In Pisaura mirabilis, opposites might attract: adventurous males and cautious females mate longer, revealing hidden personality-driven patterns in "romance". Read more here: www.ezlab.si/post/in-pisa...

Amazing congress! At EZlab, we're proud that 5 current/past members attended. :)

Our plenary talk today: Unraveling Sexual Size Dimorphism in Spiders: Current Insights and Emerging Frontiers by Simona Kralj - Fišer

Today we covered themes related to systematics & phylogenetics, evolutinary biology & genomics, and faunistics & distribution. From Nemesiidae, Salticidae and Theridiidae to scorpions and pseudoscorpions: our lecturers gave their best and gave us insight into their research.

EZ's Simona with an excellent plenary talk!

A game I get to play often in Ecuador… One of these things is not like the other. Do you see him? Imagine looking in an entire forest.

Just got back from Ecuador, where I made new friends, learned new things, and saw some cool stuff! Ecuador is a country that NEVER disappoints. This gorgeous red huntsman spider is Sadala rauli, a rainforest inhabitant that I see quite often but was only formally described as a species a year ago!

Fresh from the oven!

New species!

Holy smokes! I've got the male too! I'm tearing up. Just heard from the scientist that described the new species and this handsome lad is the male. So awesome! (Chrysometa chuchaqui)

*gasps* the pedipalps!!!

New publication! Bark spiders (Caerostris) are known for extremely large webs and toughest silk. Due to cryptic diversity, a recent genome assembly was misassigned. We redescribe valid species and newly describe the species used in the genome assembly. www.ezlab.si/post/bark-sp...

New pub! A short report on a sequence of unusual male behaviors observed in the spider species Nephila pilipes (family Nephilidae), a sexually size dimorphic tropical spider species. www.ezlab.si/post/to-mate...
