Micro-CT analysis reveals directional genital asymmetry in a mygalomorph spider with two different sperm-storage organs (Araneae: Mecicobothriidae)
Abstract. Sexual selection is a pervasive evolutionary force shaping the extraordinary diversity of animal genitalia, often driving rapid morphological div

Extreme sexual size dimorphism correlates with proxies of postcopulatory sexual selection across selected Dolomedes fishing spiders
Abstract. Sexual size dimorphism (SSD) and mating system diversity are key factors shaping reproductive evolution, yet their relationships with post-mating

An ancient genome duplication event drives the development and evolution of spinnerets in spiders
A genome duplication event during the Silurian played a crucial role in the evolutionary emergence of spinnerets in spiders.

Bark spiders are some of nature’s best engineers. They spin webs that stretch across entire rivers in Madagascar; their silk is stronger than steel—and the toughest on Earth. But only females craft the mightiest webs, according to a new study. https://scim.ag/4pmXX8B
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).
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.
EZ Lab@ezlab.bsky.social · 9mo agoNew 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...

Meet our Plenary Speaker Daniela Rößler Fueled by curiosity and a deep love of natural history Daniela discovered a REM-like sleep state in spiders and uses integrative field, lab and comparative approaches to investigate the function, ecology, and evolution of sleep across the spider tree of life.
This Male Walckenaeria acuminata may be common but its a fantastic looking spider, since getting into Linys this Genus is so fasinating. And its great that the male and female of this species can be Identified with a hand Lens. @britishspiders.bsky.social
