This moth deposits her eggs 

 in carpets, woolen goods, furs, 

 etc. As soon as hatched the 

 young larva (Fig o47a) immediately begins to construct for 

 itself a nearly cylindrical tube (Fig. 347/>), formed by fastening 

 the gnawed pieces of the cloth together with silken threads. 

 In this tube the larva lives, and instead of dragging its habita- 

 tion over the hairs, etc., it first cuts these off, thus doing more 

 injui-y than if it merely fed upon the cloth, fur, etc. When 

 fully grown, the caterpillar closes both ends of the tube and 

 soon assumes the pupa form (Fig. 347c), from which the per- 

 fect moth issues in the course of a few weeks.

Closely related to the aboNc 

 species is the carpet moth, or 

 woolen moth {Tinea taprt- 

 zella — Linn), whose larvn also 

 lives in a silken tube (Fig. 

 348) and is sometimes very 

 destructive to carjiets, etc.
