On September 12th, 2009 four specimens of the short-winged mold beetle Claviger testaceus was found in an ant nest (Lasius sp.). The species is highly adapted to the life with ants and can't survive outside the ant nest. The eyes are atrophied. The beetle excretes a secretion highly attractive to the ants, which in turn feed the beetle. The beetle also feeds on the larvae of ants. In Germany, Claviger testaceus is regarded as vulnerable (RL 3).
