Ptilodactylidae
Ptilodactylidae is a family of beetles belonging to the Elateriformia. There around 500 extant species in 35 genera. They are generally associated with riparian and aquatic habitats. The larvae generally live associated with rotting wood or vegetation, or within gravel and detritus on the edge of water bodies. The larvae of some species feed on submerged rotting wood or on plant roots, while the adults of some species are known to feed on fungus with modified brush-like maxillae.
