Lygaenocorinae Popov, 1961 (Lygaeidae)

Oxycarenus hyalinipennis is a species of plant bug belonging to the family Lygaeidae, subfamily Oxycareninae.

Geocoris is a genus of insects in the family Lygaeidae (although sometimes the subfamily is elevated to the family "Geocoridae").

The milkweed bug, Oncopeltus fasciatus, is a medium-sized hemipteran (true bug) of the family Lygaeidae.

Blissus leucopterus also known as the true chinch bug is a small North American insect in the order Hemiptera and family Lygaeidae.

Species in this family are parasites of Heteropteran bugs including Pentatomidae, Scutelleridae, Cydnidae, Coreidae and Lygaeidae.

Conversely, some predatory hemipterans are themselves biological pest control agents, such as various nabids, and even some members of families that are primarily phytophagous, such as the genus Geocoris in the family Lygaeidae.

After the ash-grey leaf bugs were recognized as Pentatomomorpha, they were most often placed in the Lygaeoidea based on cladistic analysis, with their relatives variously presumed to be the Berytidae, Colobathristidae and Malcidae, or the peculiar, beetle-like Psamminae, a subfamily of the Lygaeidae.
