Uloboridae is a family of non-venomous spiders, known as cribellate orb weavers or hackled orb weavers. Their lack of venom glands is a secondarily evolved trait. Instead, they wrap their prey thoroughly in silk, cover it in regurgitated digestive enzymes and then ingest the liquified body.[1]
All members of this family produce a feathery, fuzzy silk called cribellate (or hackled) silk.[2] 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.
Distribution
This family has an almost worldwide distribution. There are only two species known from northern Europe: Uloborus walckenaerius and Hyptiotes paradoxus. Similarly occurring solely in northern North America (e.g. southern Ontario) is Uloborus glomosus.
