Pyrrhocoridae is a family of insects with more than 300 species world-wide. Many are red coloured and are known as red bugs and some species are called cotton stainers because their feeding activities leave an indelible yellow-brownish stain on cotton crops. A common species in parts of Europe is the firebug, and its genus name Pyrrhocoris and the family name are derived from the Greek roots for fire "pyrrho-" and bug "coris". Members of this family are often confused with, but can be quickly separated from, Lygaeidae by the lack of ocelli on the top of the head.
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. Many species feed on seeds, some on sap or seed pods, others are omnivores and a few, such as the wekiu bug, are insectivores. Insects in this family are distributed across the world.
Dinidoridae is a small family of hemipteran "true bugs" comprising about sixteen genera and a hundred species the Hemiptera suborder Heteroptera. As a group the family does not have any common name. Until the late 19th century they were generally regarded as a subfamily of Pentatomidae.
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".
