These are the dominant stoneflies in Australia and occur also in New Zealand (including Auckland and Campbell Is) and in South America. Most adults are dull coloured, with wings either uniformly infuscate, darkened or brightened at the cross-veins, banded or mottled. Larvae generally range from yellow to dark greyish brown in colour and have a bunch of cylindrical anal gills between the bases of the usually long cerci; one South American genus ( Notoperla ) lacks gills. They are rather sluggish and are usually found clinging to the undersurface of rocks and debris in swift water. There are 12 Australian genera.

  • Illiesoperla sp. larvae

  • Gripopterygidae adult

  • Gripopterygidae adult

  • Dinotoperla sp.
