The larvae of the case-making 

 clothes moth. Tinea pellionella (L.), 

 live in portable parchment-like 

 cases. The webbing clothes moth, 

 Tineoia biselliella (Hummel), is 

 characterized by its larvae mak- 

 ing webs with particles on which 

 they feed. Both feed on wool, 

 hair, skin, feathers and other ani- 

 mal matter.

 dacious. They feed on fruits and leaves and some 

 mine in fruits. Some species are believed to be pre- 

 dators of mealybugs and scale-insects. They are 

 known as "sua moths."
