Rove Beetle Rove beetles are very common insects that usually go unnoticed. The result is that over half of the top surface of the abdomen is exposed.
Most rove beetles are black or brown.
One common species has grayish markings on the wings and abdomen. Most rove beetles are medium sized beetles though a few species are up to 1 inch long. Rove beetles are very active fliers or runners. When they run they often raise the tip of the abdomen. Rove beetles are completely harmless though their habits make them unappealing.
