Natural Habitat

Adults occur near streams, rivers, ponds, and other freshwater habitats; larvae live underwater, often in cases or retreats.

Diet & Feeding

Adults often feed little or not at all; larvae consume algae, aquatic plants, detritus, or small aquatic prey, depending on the species.

Behavior Patterns

Adults are mostly nocturnal and attracted to lights, with wings held roof-like over the body. Larvae undergo complete metamorphosis in freshwater and emerge as winged adults.

Risks & Benefits

Harmless to people and do not bite. Larvae are important aquatic decomposers and prey, while their presence can indicate relatively healthy freshwater.
