Scientific classification

Latreille, 1802


Hydrophilidae, also called water scavenger beetles, is a family of chiefly aquatic beetles.[1][2] Aquatic hydrophilids are notable for their long maxillary palps, which are longer than their antennae.[3] Several of the former subfamilies of Hydrophilidae have recently been removed and elevated to family rank; Epimetopidae, Georissidae (= Georyssinae), Helophoridae, Hydrochidae, and Spercheidae (= Sphaeridiinae).[1][4] Some of these formerly-included groups are primarily terrestrial or semi-aquatic.[citation needed]

The vernacular name water scavenger beetles is not an accurate description of their habit.[citation needed] With rare exceptions, the larvae are predatory while the adults may be vegetarians or predators in addition to scavenging.[5] Many species are able to produce sounds.[citation needed]

Species of Hydrophilus are reported as pests in fish hatcheries.[5] Other species are voracious consumers of mosquito larvae, and have potential as biological control agents.[5][6] There are 2,835 species in 169 genera [7]
