Spiders in the family Uloboridae are the only spiders in the world that do not possess venom glands. They wrap their prey in silk and cover it in digestive enzymes. Several genera exist, with webs ranging from perfectly horizontal orb webs (Uloborus spp) to single horizontal silk lines (Miagrammopes spp). Uloborus spp have long front legs held forward and slightly apart and a very bulbous abdomen. Miagrammopes hold their long front legs in a similar fashion, but have long slender abdomens, giving the spider a curious shape.
LIFESTYLE: Sedentary and web-bound
HABITAT: On bushes and low vegetation and around the eaves of buildings
BODY SIZE (excluding legs): 3-10 mm
DANGER: Harmless (more harmless than any other!)
