What is the family name of riffle beetles?

The family name of riffle beetles is Elmidae. Riffle beetles are aquatic insects commonly found in fast-flowing streams and rivers, where they are adapted to live among gravel and pebbles. Members of the Elmidae family are characterized by their flattened bodies and short antennae, features that help them remain in position in their turbulent aquatic habitats. They play an essential role in the ecosystem as decomposers, feeding on decaying organic materials. The identification of riffle beetles within the Elmidae family is based on morphology and behavioral traits that are specific to this group, distinguishing them from other families of aquatic beetles.
