Life Cycle Tyoically static in a stance with fore-legs spread wide, waiting for insects to contact within them. Predatory on other invertebrates, including ants, which most other spiders avoid, and often taking prey much larger than themselves. Called 'crab spiders' because, as the name suggests, they sometimes move in a crab-like way, from side to side. Male courtship unusual method of mating with the female.initially grabing hold of one of her legs waiting until struggling stops. He then ties her down to the ground with threads of silk. In the last phase of courtship he crawls underneath her to mate.
Habitat On the ground or in low vegetation.
