Order:
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.
Family:
The larva lives in a case that is composed of two flat pieces of dead leaves or in a piece of wood or a stick in which it has gouged its living space; the tops of the first two thoracic segments are covered by sclerites; the top of the third thoracic segment has only a few small sclerites; the top of the labrum (upper lip) has a transverse row of about 16 setae; anal prolegs are mostly fused with the end of the abdomen except their apical hooks.
