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.
