Our largest horse-fly is an inch long, with a two-inch wing expanse, and of a dull black color, while other common, smaller species are brown, with the wings banded with black. Only the females are bloodsuckers, the males feeding on the pollen of flowers. The soldier-flies {Stratiomyidae) somewhat resemble the smaller horse-flies, and are so named on account of the bright yellow or green stripes across the abdomen. The antennas are somewhat longer.

The adults are found on flowers near water, and the larvae are carnivorous or feed on decaying vegetable matter, living in water, earth, or decaying wood. In the second group are found two families having four or five distinct antennal segments,—the robber-flies (Asilidac) and the nearly related Midas-flies {Midaidac), which have very similar habits. The robber-flies (Asilidae). They are well named, being large, hairy, ferocious-looking flies, which are strong, swift flyers. They may often be seen resting quietly on a dead twig, which they closely resemble in color; suddenly they will dart off and in mid-air will snatch a fly or any insect which they can overpower, in much the.
