Our 9 species of bittacids are widely distributed and often fairly common. Most are light brown and long-legged, about 20-25 mm., and often resemble large crane flies. Some have brownish areas on certain cross veins, and 1 species has blackish wing tips. This species holds its wings outstretched at rest; others fold the wings back over the abdomen. Bittacids spend most of their time hanging from vegetation by their front legs. They feed on various small insects which they capture with their raptorial hind feet. One California species is wingless.
