Pentatomidae is a family of insects belonging to the order Hemiptera, generally called shield bugs or stink bugs. Pentatomidae is the largest family in the superfamily Pentatomoidea, and contains around 900 genera and over 4700 species. As hemipterans, the pentatomids have piercing sucking mouthparts, and most are phytophagous, including several species which are severe pests on agricultural crops. However, some species, particularly in the subfamily Asopinae, are predatory and may be considered beneficial.
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.
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".
