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
