The Angoumois Grain Moth. 



(Gdechia cercdlella. — Linnams.) 



Order, Lepidoptera ; Family, Tixeid.e. 



[Liviii^f in grains of wheat and corn; a minute white 

 larva.) 



This 25Cf't is very destructive to stored wheat and corn, 

 especially to the former. It eats out the interior of the grain, 

 leaving nothing but the empty hull. It is said that a single 

 grain furnishes sufficient food for a larva from the time it 

 issues from the egg until it becomes fully grown. It assumes 

 the pupa form within the grain, or hull. The perfect moth 

 (Fig. 356) has the liead of a dull ochre color, the fore-wings 

 palo shining ochre, with a grayish or brownish streak at the 

 liasc of each wing; tlic bind wings are also grayish-ochre.

Closely related t<^ the above is the common grain moth 

 (Tinrn (irnnrJUi — Ivinn), sometimes called the "grain wolf." 

 Its larva' did'ors from that of the Angoumois moth by fasten- 

 ing several grains together witb silken threads and afterwards 

 eating out the interior of each grain. The perfect moth is of 

 a creamy-wliitc color, witli six lirown spots on each fore-wing.
