The Coreidae are a large family of predominantly sap-sucking insects in the Hemipteran suborder Heteroptera. The name "Coreidae" derives from the Ancient Greek meaning bedbug.
As a family, the Coreidae are cosmopolitan, but most of the species are tropical or subtropical.
The common names of Coreidae vary regionally. Leaf-footed bug refers to leaf-like expansions on the legs of some species, generally on the hind tibiae. In North America, the pest status of species such as Anasa tristis on squash plants and other cucurbits gave rise to the name squash bugs. Coreidae are called twig-wilters or tip-wilters in parts of Africa and Australia because many species feed in young twigs, injecting juices that the tissues of the growing tips and cause them to wilt abruptly.
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. They vary in size from 7 to 45 mm long, which implies that the family includes some of the biggest species of Heteroptera. The body shape is quite variable; some species are broadly oval, others are elongated with parallel sides, and a minority are slender. Many species with the "leaf-footed" tibiae are very slender with conspicuous expansions of the hind tibiae, but some robust species also have decided expansions. Some species are covered with spines and tubercles. As an example of these, the tribe Phyllomorphini Mulsant & Rey, 1870, are strikingly , with thin legs, spiny bristles, and outlines and adornments.
