Robber Fly

Description:

Adult stages are medium to large (3/8 to 1-1/8 inch) flies often observed on stems of plants, on the ground or flying low. Species vary in appearance and some mimic wasps and bees. Most species are gray to black, hairy-bodied, have a long, narrow, tapering abdomen containing segments that may be banded, patterned or contrasting in color. The heads of adults have a depression between the eyes when viewed from the front. They have long, strong legs for grabbing prey.

Habitat:

Miller Springs Park is a 360-acre park located below Belton Lake, on the Leon River, in Bell County, Texas. It contains diverse riparian terrain, including limestone bluffs, estuarial wetlands, mountain cedar hilltops, and riverside cottonwood stands. Numerous trails traverse prairie-like open spaces and forests of native cedar elm, live oak, and red oaks. Recent floods have created a new canyon that reveals numerous layers of sedimentary rock and fossils. Area wildlife includes white-tail deer, red foxes, coyotes, black squirrels, armadillos, and about 200 species of birds in the course of the year.
