(leaf bugs), a family of true bugs. Leaf bugs are 3–10 mm long and vary in color from straw-yellow or green to reddish brown or black. Sometimes there are markings: black stripes and dots on a light background or yellow or whitish stripes and dots on a black background. The antennae are usually longer than the head. The proboscis has four segments. The ocelli are wanting, but the wings are usually developed. There is an ovipositor. The leaf bugs are represented by a large number of cosmopolitan species. There are about 700 species in the USSR. The insects are herbivores or, less commonly, carnivores or omnivores. They inhabit herbaceous plants and trees. Crop pests include the alfalfa bug (Adelphocoris lineolatus) and the beet bug (Poeciloscytux cognatus).
