Leuctridae is a family of rolled-winged stoneflies. This family includes 13 genera and more than 300 described species.

Description

These small stoneflies can reach a length of 5–13 millimetres (0.20–0.51 in), but most of the species are less than 1 centimeter. The wings are slender and cylindrical, usually dark-brown. At the rest the wings appear wrapping the bodies. The adults develop in early spring, swarm, mate and lay the eggs in the water. The slender yellowish larvae are herbivorous, feeding on plants and organic waste.

Distribution

They have a mainly Holarctic distribution.
