Gray wall jumpers are dorso-ventrally flattened and are covered with short dense, grayish-white hairs.

[2] The female gray wall jumper builds an eggsac in a crack or other concealed position in which she lays 25 to 40 eggs in a purse-like silken case.

[2] Male spiders of this species possess a stridulatory apparatus which consists of several long bristles on the palpal femur and a series of horizontal ridges on the outer side of the chelicerae.

It moves actively about in search of small insect prey, often vibrating its hairy palps as it walks.

[7] In America, the species is found in Florida, Texas, and California (USA) and south as far as Paraguay, including some Caribbean islands, Colombia, and Venezuela.
