Size
adult body 10-15 mm
Identification
Adult: head and body with patches of short hair; forewing light to medium brown or grayish, often with speckling, mottling, or patches of pale yellowish or cream color; anal angle of forewing relatively sharp-angled (outer margin of wing may be slightly concave near anal angle)
Larva: many species have distinctive pattern on top of head; dorsal plate on each thoracic segment; rows of bushy gills on abdomen
Range
worldwide
Habitat
larvae in fast-moving portions of streams and rivers; adults on nearby vegetation, and are attracted to artificial light
Food
larvae are filter-feeders, eating algae, detritus, and particles of organic material captured in their nets
Remarks
Larvae spin a concave net, facing upstream, in front of a sheltered retreat in debris or under stones, and wait for food to be captured in the net. Some species build nets under the brink of a waterfall, causing a brown coating of sediment to form on the rocks.(3)
