All members of this family of arachnids produce a feathery, fuzzy silk called cribellate (or hackled) silk. These spiders do not use an adhesive on their orb webs, but rather the very fine fibers on each strand of silk tend to ensnare prey. Uloboridae webs often have a stabilimentum or zig-zag pattern through the center.1
