The Hydrophilidae, or water scavenger beetles, received their name from the genus Hydrophilus, a word of Greek origin meaning, "a lover of water." They are usually found in ponds and streams. Several genera are, however, terrestrial in habit, living in moist earth and in the dung of cattle and horses, where they are said to feed upon the larvae of dipterous insects. The family consists of some 1,700 species, mostly tropical, but well represented in the temperate regions. About 190 species are known from the United States.
