                           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.

                           The larva lives in a case that is made of small stones and shaped like a tortoise shell; the top of the first thoracic segment is covered by sclerites, but the tops of the other two thoracic segments may or may not have a few small and usually inconspicuous sclerites; there is a sclerite on the top of the 9th abdominal segment; the anal prolegs are partly fused with the end of the abdomen.
