When removed from the corn ear the caterpillar coils up after the 

 manner of a cut worm. In fact this species belongs to the same 

 natural family as the cut worms (Xoctuidae). 



The wings of the moth when expanded cover about one inch 

 and a half. Like the caterpillar it varies greatly in color, having 

 however, in all specimens a prevailing yellowish cast. They may 

 be grayish or clay-yellow and many have a distinct olive green 

 cast. The markings also vary in distinctness. Those most plainly 

 marked have two faint brown bands across the fore wings and a 

 mo'-c cistmct onv nearer the extremity of ihe wings and parallel 

 with the outer edge.

A row of black dots on a whitish back ground occurs next the 

 edge of the wing. A crescentic discal spot occurs on each fore wing. 

 The hind wings are much paler in color, particularly near their 

 bases. A broad submarginal band occurs on the outer end. 



The eggs, of which the moth may lay about 500, are whitish in
