Good Bug Corner – Rove Beetles

This week’s Good Bug Corner featured ent.knodel.6.rove beetleinsects are the Rove Beetles in the insect family Staphylinidae. This beetle family has the largest number of species with over 3,000 species known from North America. Rove beetles have an elongated body with short wing covers and range in size from 7-25 mm. When disturbed, rove beetle raise up and wave their abdomens like a scorpion, but they can’t sting. They live in moist environments and occupy diverse habitats from forest to grasslands to field crops. Rove beetles are mainly scavengers feeding on decaying organic matter; however, some species are important predators of insect/mite eggs, aphids, larvae/maggots, mosquito larvae, springtails and fleas. For example, Tachyporus has been used as a predator of cereal aphids and Aleochara as a predator of root maggots. Rove beetle also feed on insects that infest decaying animal carcasses.
