clothing we should find the case-making species more 

 abundant. A more detailed investigation of the life 

 history, habits, and distribution of these moths is much 

 needed. 



The moths (Fig. 52) of the case-making species are 

 small, measuring only about half an inch from tip to tip 



of the tiny wings when 

 they are squarely ex- 

 panded. The fore wings 

 are of a shining yellowish-

 quently seen flying aimlessly about a lamp at night. The 

 moths, of course, are innocent enough, so far as any actual 

 direct damage to clothing is concerned. Nevertheless 

 much energy is expended by the careful housekeeper in 

 catching and killing them. This energy, however, is not 

 wholly lost, for if the moths are allowed to live, they may 

 deposit eggs for the production of larvse, the real authors 

 of the injury. Undoubtedly, many small, harmless 

 moths are often mistakenly destroyed for the more injuri-

The tiny eggs of this moth are tucked away among the 

 folds of the garments upon which the larva? are expected 

 to feed. When they hatch, the minute white-bodied
