                           Larvae: Wings/wing pads absent. Eye spots present, but compound eyes absent. Antennae usually small, inconspicuous. Three pairs of segmented legs present on thorax. Pair of anal prolegs, each with single hook, located on last abdominal segment. Larvae can be free-living, in silken retreats attached to substrate, or in usually-portable tubes or cases made of sand, rocks, or plant material.

                           Antennae usually long for caddisflies, at least 6 times as long as thick. Mesonotum light in color, except sometimes with pair of dark curved lines; these lines present in species with short antennae. Metanotum membranous. Larvae constructing portable tube-shaped cases of various materials and shapes.
