Coreidae is a large family of predominantly sap-sucking insects. The common names of the Coreidae vary regionally. Leaf-footed bug refers to leaf-like expansions on the legs of some species, generally on the hind tibiae.
Coreidae commonly are oval-shaped, with antennae composed of four segments, numerous veins in the membrane of the fore wings, and externally visible repugnatorial stink glands. They vary in size from 7–45 mm long, which implies that the family includes some of the biggest Heteropterans. The body shape is quite variable; some species are broadly oval, others are elongated with parallel sides, and a few are slender.
In the nymphs, the openings of the two repugnatorial stink glands of the Coreidae are visible as two projections or spots on the medial line of the dorsal surface of the abdomen, one at the anterior and one at the posterior edge of the fifth abdominal tergite above the glands inside.
