The Indian meal moth 1 is one of the more common of 

 these species. The whit- 

 ish, brown-headed cater- 

 pillar lives in a large 

 variety of substances, in- 

 cluding all cereal prepa- 

 rations and such diverse 

 materials as various nuts, 

 dried fruits, seeds etc. 

 The caterpillar spins a 

 light web to which par- 

 ticles of its food and frass 

 adhere. The parent moth 

 is reddish brown, with a 

 coppery luster and has a wing spread of about f of an inch. 



The meal snout moth 2 subsists mostly upon cereals though it 

 has been recorded as feeding upon other seeds and dried plants
