Coccinellidae prey species that various Coccinellidae may attack is much wider. A genus of small black ladybirds, "Stethorus", presents one example of predation on non-Sternorrhyncha; they specialise in mites as prey, notably "Tetranychus" spider mites. "Stethorus" species accordingly are important in certain examples of biological control. They are natural predators of a range of serious pests, such as the European corn borer, a moth that costs US agriculture industry more than $1 billion annually in crop losses and population control. Various larger species of Coccinellidae attack caterpillars and other beetle larvae. Several genera feed on various insects or their eggs; for
Common name not always English. For example, "Dikkop" is the centuries-old South African vernacular name for their two local species: "Burhinus capensis" is the Cape dikkop (or "gewone dikkop", not to mention the presumably much older Zulu name "umBangaqhwa"); "Burhinus vermiculatus" is the "water dikkop". The thick joints in question are not even, in fact, the birds’ knees, but the intertarsal joints—in lay terms the ankles. Furthermore, not all species in the genus have “thick knees”, so the thickness of the "knees" of some species is not of clearly descriptive significance. The family Burhinidae has members that have various common names even
