Sphaeridiinae

Sphaeridiinae is a subfamily of water scavenger beetles (insects in the family Hydrophilidae). Some species live in fresh water as both larvae and adults.

== Habitat == Sphaeridiinae is a subfamily of Hydrophilidae that is considered mostly terrestrial compared to the other aquatic subfamilies in the larger overarching family of Hydrophilidae. There have been some instances of this subfamily living in riparian habitats or floating vegetation, however, this subfamily is not constrained to aquatic ecosystems. In general, Hydrophilidae species have larvae that are aquatic or terrestrial and the adults are mainly aquatic. In Sphaeridiinae's case, there has been a trend for it to colonize on solely moist terrestrial land, including places of decomposition.
