	Long-toed Water Beetle Dryopidae is a family of beetles, commonly named long-toed water beetles, in the superfamily Byrrhoidea. It was described by Gustaf Johan Billberg in 1820. Description Long-toed water beetles are named for their extended claws. Adults have dense hairs, which allow the beetles to breathe while underwater. The flight muscles of the females weaken as they age. When the pupae complete the imago stage of their life cycle, they move towards running water, and may be attracted to lights. Despite being referred to as aquatic insects, the beetles are unable to swim, clinging to detritus that float. All long-toed water beetles feed on plants that are in the water, but the larvae generally are terrestrial, and at least some also feed on plant matter. ''Stygoparnus'' is the only genus in the family in which both the larvae and adults are aquatic. Genera of the family closely resemble riffle beetles, but the antennae are different from the long-toed water beetles, looking similar to clu ...
