Coreidae is a large family of predominantly sap-sucking insects in the Hemipteran suborder Heteroptera. The name "Coreidae" derives from the genus Coreus, which derives from the Ancient Greek κόρις (kóris) meaning bedbug.
The Pentatomomorpha comprise an infraorder of insects in the true bug order Hemiptera. It unites such animals as the stink bugs (Pentatomidae), flat bugs (Aradidae), seed bugs, etc. They are closely related to the Cimicomorpha.
Coreoidea is a superfamily of true bugs in the infraorder Pentatomomorpha which includes leaf-footed bugs and allies. There are more than 3,300 described species in Coreoidea.
The Lygaeidae are a family in the Hemiptera, with more than 110 genera in four subfamilies. The family is commonly referred to as seed bugs, and less commonly, milkweed bugs, or ground bugs. However, while many of the species feed on seeds, some feed on sap (mucivory) or seed pods, others are omnivores and a few, such as the wekiu bug, are carnivores that feed exclusively on insects. Insects in this family are distributed across the world, including throughout North America. The family was vastly larger, but numerous former subfamilies have been removed and given independent family status, including the Artheneidae, Blissidae, Cryptorhamphidae, Cymidae, Geocoridae, Heterogastridae, Ninidae, Oxycarenidae and Rhyparochromidae, which together constituted well over half of the former family.
Piesmatidae is a small family of true bugs, commonly called ash-grey leaf bugs. The Piesmatidae are distributed mostly in the temperate Northern Hemisphere, with some occurring in Africa, Australia and South America. A common species found throughout the Americas is Piesma cinereum.
The Blissidae are a family in the Hemiptera, comprising nearly 50 genera and 400 species. The group has often been treated as a subfamily of the Lygaeidae but was resurrected as a full family by Thomas Henry (1997).
Cydninae is a subfamily of burrowing bugs in the family Cydnidae. There are about 11 genera and at least 40 described species in Cydninae.
Aneurinae is a subfamily of flat bugs in the family Aradidae. There is at least 1 genus, Aneurus, in Aneurinae.
Oxycarenidae is a family of true bugs in the order Hemiptera. There are more than 20 genera and 140 described species in Oxycarenidae.
Cymidae is a family of true bugs in the order Hemiptera. There are about 12 genera and at least 60 described species in Cymidae.
Geocoridae is a family of big-eyed bugs in the order Hemiptera. There are more than 290 described species in Geocoridae.
Meropachyinae is a subfamily of leaf-footed bugs in the family Coreidae. There are at least 50 described species in Meropachyinae, recorded from the Americas.
Metacanthinae is a subfamily of stilt bugs in the family Berytidae. There are about 12 genera and 80 described species in Metacanthinae.
Artheneidae is a family of true bugs in the order Hemiptera. It was formerly included in Lygaeidae. There are about 7 genera and at least 20 described species in Artheneidae.
Gampsocorinae is a subfamily of stilt bugs in the family Berytidae. There are about 60 described species in Gampsocorinae.
Pachygronthidae is a family of true bugs in the order Hemiptera. There are about 14 genera and more than 80 described species in Pachygronthidae.
Colobathristidae is a family of true bugs in the order Hemiptera. There are more than 20 genera and 90 described species in Colobathristidae.
Cryptorhamphidae is a family of true bugs in the order Hemiptera. There are at least two genera and four described species in Cryptorhamphidae.
Malcidae is a family of true bugs in the order Hemiptera. There are at least 4 genera and more than 40 described species in Malcidae.
Ischnorhynchinae is a subfamily of seed bugs in the family Lygaeidae. There are about 16 genera and more than 70 described species in Ischnorhynchinae. The members of this subfamily are small, terrestrial insects that typically translucent or transparent plate-like structures covering the thorax (pronota) and tend to live in plant flowers.
