Atheta coriaria

Predator of Soil Pests

Adult Atheta beetles are dark brown to shiny black, 3 to 4 mm long and are completely covered with hair. Athetahas three larval stages during which the larvae change from white to orange brown. All stages of Atheta actively search for prey. Because of their flight capability, adults can travel through a greenhouse, which ensures good distribution and fast population development. Total development time from egg to adult takes about three weeks at 25ºC. After that period the adult predatory beetle will be active for approx. three weeks. An adult female will lay 8 eggs per day during the first two weeks after maturing.
