The larvae of moths of the family Psychidae built small protective cases in which they hide. The materials used vary, and may include inorganic material such as sand grains, as well as organic materials, such as dead plant material, but incidentally also lichens. Luffia ferchaultella has used material from Lecanora expallens or L. compallens; the unidentified species shown here has built the case from Cladonia podetia.
