Cribellate Orb Weaver 
Uloborus plumipes Scientific classification Kingdom: Animalia Phylum: Arthropoda Class: Arachnida Order: Araneae Suborder: Araneomorphae Superfamily: Uloboroidea Family: Uloboridae
Thorell, 1869Diversity 18 genera, 262 species 
Uloboridae, the cribellate orb weavers or hackled orb weavers, is a family of non-venomous spiders. Their lack of poison glands is a secondarily evolved trait. Instead, they kill their prey by crushing with over 140 metres of thread.
All members of this family produce a feathery, fuzzy silk called cribellate (or hackled) silk.[1] 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.
