The 3 to 3.5 mm large diving beetle Hygrotus versicolor (family Dytiscidae) is one of 4 representatives of the genus Hygrotus in Germany. The genus Hygrotus is of holarctic distribution and comprises approx. 70 species, thereof 40 in North America. It is closely related with genus Coelambus, which is regarded as subgenus of Hygrotus by some authors. Hygrotus versicolor is known to occur in North and Central Europe and reaches Transcaucasia and Siberia in the East. Towards the south it becomes rarer. The eurytopic species prefers lentic waters, e.g. oxbow lakes rich in vegetation, gravel pits and small meadow ponds. Both beetles and larvae prey on other water insects and small crustaceans. In Germany, Hygrotus versicolor has been recorded from all Federal States and is not regarded as endangered. (CB)
