Noctuidae 
It is 
a very common species in the Atlantic States, 
and at times does considerable 
injury to the crops. It has never, 
however, equaled in destructiveness 
the first species of the genus, to which 
we have given our attention on the 
preceding pages. It is said to be 
particularly attracted to the wheat 
when the grain is in the milk and 
the heads are just maturing. The 
damage done at this time is, in the 
Middle States, where winter 
wheat is commonly grown, due to 
the first generation of the insects. 
There are in fact two broods, one 
appearing on the wing in spring or 
early summer, the second in the late 
summer. The latter brood, which 
generally is more numerous than the 
first, produces the caterpillars, the 
pupae of which yield the moths, 
which,' v coming out in the spring of 
the year, lay their eggs in the wheat- 
fields. It is said that the habit of 
attacking wheat in its period of matu¬ 
ration has lately been acquired by this 
insect, and is an illustration of the 
way in which species, long regarded 
as innocuous, develop with apparent 
suddenness destructive tendencies.
