Coreidae are a large family

Family (biology)

In biological classification, family is* a taxonomic rank. Other well-known ranks are life, domain, kingdom, phylum, class, order, genus, and species, with family fitting between order and genus. As for the other well-known ranks, there is the option of an immediately lower rank, indicated by the...

Heteroptera

Heteroptera is a group of about 40,000 species of insects in the Hemiptera. Sometimes called "true bugs", that name more commonly refers to Hemiptera as a whole, and "typical bugs" might be used as a more unequivocal alternative since among the Hemiptera the heteropterans are most consistently and...

. 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

The tropics is a region of the Earth surrounding the Equator. It is limited in latitude by the Tropic of Cancer in the northern hemisphere at approximately  N and the Tropic of Capricorn in the southern hemisphere at  S; these latitudes correspond to the axial tilt of the Earth...

In North America they are colloquially called "squash bugs", because some species, such as Anasa tristis, are pests of squash plants and other curcubits

Coreoidea

The leaf-footed bugs and allies make up the superfamily Coreoidea of the true bug infraorder Pentatomomorpha.There are 5 families presently recognized, but the Coreoidea as a whole are part of a close-knit group with the Lygaeoidea and Pyrrhocoroidea and it is likely that these three superfamilies...

Morphology

The general morphological features of Coreidae are an oval-shaped body, antennae composed of four segments, a numerously veined forewing membrane, a metathoracic stink gland and enlarged hind tibia. Many species are covered with spines and tubercles.
