Coreidae is a large family of predominantly herbivorous insects that belong in the hemipteran suborder Heteroptera. There are more than 1,800 species in over 250 genera.
They vary in size from 7 to 45 mm, making the larger species some of the biggest heteropterans. The body shape of coreids is quite variable, with some species broadly oval while others are slender. Coreids are found throughout the world but most species are found in the tropics and subtropics.
In North America they are colloquially called "squash bugs", because some species, such as Anasa tristis, are pests of squash plants and other cucurbits.
They are also called “leaf-footed bugs” due to the leaf-like expansions some species have on their hindlegs.
