As part of the Crab Spider family, this spider is comfortable stretching its first 2-3 pairs of legs forward, giving it more of a crab-like appearance. They are able to walk sideways and backward as well as forward. Females are heavier, but males have longer legs.
They are night predators, preying on cockroaches and other insects traveling the bark of trees. They sometimes make their way into houses and barns, but, in many areas, are welcomed by homeowners thanks to their diet of nuisance insects. They also eat scorpions and small bats if they can catch them.
Males shake their legs, creating a dull, low buzzing sound in an effort to attract females. Females lay fertilized eggs in silken sac and carry it around in their jaws until the spiderlings hatch.
