Hydrochidae (water scavenger beetles)

Spercheidae  
The water scavenger beetles (Hydro­chidae) are a family of small beetles of oblong body shape. Their protruding eyes are the most remarkable morphological feature. Formerly the family was included in the Hydraenidae, today some authors consider them to be a subfamily of Hydrophilidae. The family comprises only the genus Hydrochus. The species live in lentic waters with rich vegetation and can be found crawling on vegetation. Worldwide, about 180 species have been described from all zoogeographical regions. In Germany seven species are known to occur.
