Notes

These small flying insects have aquatic larvae that form cases composed of bits of detritus, plants or sand grains. Larvae of members of the Helicopsychidae make snail-like cases usually using sand grains, while members of the Odontoceridae make tapering tubes resembling scaphopod shells but composed of sand grains.
