The Leuctridae are a family of rolled-winged stoneflies, and are also sometimes known as needleflies, [1] This family includes 13 genera and more than 300 described species.[2]


These small stoneflies can reach a length of 5–13 mm (0.20–0.51 in), but most of the species are less than 1 cm. The wings are slender and cylindrical, usually dark brown in color. At rest, the wings appear to be wrapping their 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.


They have a mainly holarctic distribution.
