The genus Orius (commonly called minute pirate bug) consists of omnivorous bugs in the family Anthocoridae (pirate bugs). Adults are 2–5 mm long and feed mostly on smaller insects, larva and eggs, such as spider mites, thrips, jumping plant lice, and white fly, but will also feed on pollen and vascular sap.
Some species are raised commercially and sold to growers as a form of biological control.
