Gray Wall Jumping Spider

Natural history and identification

The gray wall jumper has a relatively flattened body and hunts small flies on building surfaces. Females are largely gray; males show stronger contrasting stripes. It catches prey by stalking and jumping rather than with a capture web. Females shelter and guard their eggs in a silk retreat in a crevice. The detailed feeding and nesting account is based on observations outside Hawaiʻi.
