Pentatominae is a subfamily of Pentatomidae, a family of shield bugs. This subfamily is the largest one within the Pentatomidae, having 4937 species classified in 938 genera. Species in this subfamily are phytophages and several of them are considered agricultural pests. Some invasive pentatomines such as Halyomorpha halys and Bagrada hilaris have been considered household pests. Higher systematics of the group have been revised by Rider et al.
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. 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.
Nysius wekiuicola is a species of wēkiu bug endemic to the area surrounding the summit of Mauna Kea, on the island of Hawaiʻi. It is closely related to Nysius aa, which is endemic to the summit of the neighboring Mauna Loa.
Nysius aa is a species of wēkiu bug endemic to the area around the summit of Mauna Loa, on the island of Hawaiʻi. It is closely related to Nysius wekiuicola, which is another species of wēkiu bug endemic to the nearby Mauna Kea.
Heterogastridae is a family of lygaeoid bugs consisting of about 20 genera and more than 100 species.
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).
Ischnodemus is a genus in the true bug family Blissidae. The review by Slater (1979) listed 95 species. The genus is found in all major zoogeographic regions, being most abundant on various species of Gramineae. The bodies of the adults are moderately to very elongated. The genus name was coined to refer to this slenderness, from the Greek ἰσχνόσ (ischnos) "feeble" and δέμασ (demas) "body".
Dysdercus is a widespread genus of true bugs in the family Pyrrhocoridae; a number of species attacking cotton bolls may be called "cotton stainers".
Lygaeinae is a subfamily of ground bugs in the insect family Lygaeidae.
Lygaeus is a genus of seed bugs in the family Lygaeidae. There are more than 60 described species in Lygaeus.
Orsillini is a tribe of seed bugs in the family Lygaeidae. The type genus is Orsillus.
Orsillinae is a subfamily of seed bugs in the family Lygaeidae. There are at least 110 described species in Orsillinae; the type genus is Orsillus.
Myodochini is a tribe of dirt-colored seed bugs in the family Rhyparochromidae. There are more than 80 genera and 370 described species in Myodochini.
Lygaeospilus is a genus of seed bugs in the family Lygaeidae. There are at least four described species in Lygaeospilus.
Kleidocerys is a genus of seed bugs in the family Lygaeidae. There are about 17 described species in Kleidocerys.
Oncopeltus is a genus of seed bugs in the family Lygaeidae, which has at least 40 described species.
Xyonysius is a genus of seed bugs in the family Lygaeidae. There are about eight described species in Xyonysius.
