Uloboridae
2 species
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.
This family has an almost worldwide distribution. Only two species are known from Northern Europe: Uloborus walckenaerius and Hyptiotes paradoxus. Similarly occurring solely in northern North America (e.g. southern Ontario) is Uloborus glomosus. The oldest known fossil species is Talbragaraneus from the Late Jurassic (Tithonian) Talbragar Fossil Bed of Australia.
