Pupation occurs in moist leaf litter or the soil. A. bilineata adults are glossy black with short coarse hairs and are about 5-6 mm long. Larvae are cream colored to brown depending upon their age. Even with a 30% mortality rate from egg to adult, the progeny from one female could number nearly 422,000 females in only three generations. Because rove beetles are a generalist predator, they may feed upon beneficial species. Like the adults, the larvae often have a pair of projections alongside the tip of the abdomen.

The classification of rove beetles and related groups is ever-changing, and some entomologists estimate that Staphylinids may eventually number well over 100,000. Rove beetle larvae typically inhabit moist environments, such as in soil covered by decaying leaf litter. In the fall, the adult offspring of those overwintering adults that are observed feeding on canola leaves, stems and seed pods. The eggs are laid in decaying matter and soil before hatching.

Should a Stenus rove beetle suffer the unfortunate mishap of slipping into the water, it will release a chemical from its hind end which magically lowers the surface tension behind it, effectively thrusting it forward.

Some rove beetles react to perceived threats by tipping their abdomens up, as scorpions do, but this gesture is all bark and no bite. Once established in a greenhouse, they will be there year round, but population levels vary depending upon prey populations. The rove beetles are a family (Staphylinidae) of beetles, primarily distinguished by their short elytra (wing covers) that typically leave more than half of their abdominal segments exposed. They are slender, elongate beetles with the distinctive characteristic of having wing covers elytra that are much shorter than the abdomen. The life cycle of rove beetles from egg to adult is about three weeks at 77° F. Adult females lay approximately 8 eggs per day for the first two weeks after they mature. In contrast to fire, forest harvesting does not directly destroy the rove beetle community, but to a large extent it destroys the forest habitat. The larvae feed and molt until they are ready to pupate. More research and grower experience is needed to determine their effectiveness under New England greenhouse conditions. The rove beetles are the largest North American beetle family. The sex ratio is an equal, 1:1 females to males. Though the family Staphylinidae numbers well over 40,000 species worldwide, we still know relatively little about rove beetles.

Understanding the life cycle of rove beetles is one way of helping with identification of these insects. Appearance. As all beetles do, rove beetles undergo complete metamorphosis. When the adults emerge, they are very active, especially at night. The life cycle from egg to adult lasts approximately 37 days, with three to four of the days in the egg stage, 14 days in larval development, and 16 days in the pupal stage (Kramer 1955). (There are three larval stages after which they pupate.) Paederus beetles defend themselves by emitting the toxic pederin chemical when threatened. As all beetles do, rove beetles undergo complete metamorphosis. Most rove beetles are black or brown. It usually lives near drainage lines and watercourses. Adult beetles have a large mandible that they use to grasp prey. Rove beetles are often abundant in habitats with large numbers of fly larvae — especially decaying fruit, decaying seaweed, compost, carrion, and dung — where some are important predators of maggots and others prey on mites or nematodes. Each A. bilineata female can produce approximately nine to 15 eggs per day or 700 eggs in its lifetime (Broatch et al. Like most rove beetles, Creophilus maxillosuscan be found i… The young larvae emerge in about a week and will feed on the carcass for up to a month before pupating. In the spring, overwintered adults emerge and feed on canola seedlings. The adult carrion beetles lay eggs on or near a decomposing carcass. Rove Beetle. With roughly 63,000 species in thousands of genera, the group is currently recognized as the largest extant family of organisms. The Rove Beetle Life Cycle . Within the family, however, you’ll find rove beetles that specialize on a diet of fungal spores, others that eat pollen, and still others that feed on the regurgitated food from ants. The Histeridae larvae are destructive and when they hatch they eat the maggots in the dead body. Rove beetles were first introduced as a biological control agent in 2002. They are slender, elongate beetles with the distinctive characteristic of having wing covers (elytra) that are much shorter than the abdomen. Rove beetles have mouthparts modified for chewing, often with long, sharp mandibles that close sideways across the front of the head.
