Hydrochara
water scavenger beetles
Hydrochara is a genus of water scavenger beetles (Hydrophilidae) containing 23 species distributed across North America, Europe, Asia, and Africa. The genus was revised taxonomically in 1980, with 21 species recognized at that time and multiple synonymies established. Species in this genus are aquatic and have been studied for their potential role in biological control of mosquito larvae. At least one species, Hydrochara rickseckeri, is endemic to California.
