The 5.5 to 7 mm large rove beetle Bledius tricornis (family Staphylinidae) is one of 40 representatives of the genus in Germany, which are not easily distinguished. The stenotopic species is known to occur in the southern Palearctic, from Southern Europe to the southern part of Northern Europe, Asia Minor, the Caucasus to South Siberia and China. The beetles are halotolerant, they can be found both on the coast and in the inland on sandy and loamy substrates. The front legs are of the fossorial type. The beetles dig burrow systems into the soil. When flushed with water, they come to the surface. Presumably they feed on algae. On warm days, the beetles swarm during dusk and are attracted to light sources. Bledius tricornis is recorded from virtually all Federal States, but is regarded as vulnerable (RL 3). (CB)
