Coreidae is a large family of predominantly sap-suckling insects in the Hemipteran suborder Heteroptera. The 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. Another common name for them is "stink bugs."
