partially folded and laid upon the abdomen, and the fore wings 

 overlap them in the form of a roof. 



Their flight is strong and swift, and mainly confined to the night 

 time. They are often drawn in large numbers into the houses in the 

 evening, being attracted by the light within. "When disturbed in 

 the day time, they dart out from their place of concealment, and 

 with a rapid flight quickly seek shelter again. 



Fig 8. Army Worm Moth. 



In thf arcompamiag fi?nre 8, a represents a male moth, natural size; b, the «bdomen of 

 UV female; c. the eye magnitied; d. the base of the male antenna', and e, the bass of the 

 female antenna, enlargea. 



The army worm is usually regarded as single brooded, especially 

 in the more northern states, but the fact that the moths are seen 

 often early in the spring, and again in much larger numbers later in 

 the season, usually in this section, in July and August, would lead 

 us to conclude that there are sometimes at least two broods of 

 moths, and probably of worms, a year. Moths are usually short 

 lived, and it is hardly to be supposed that those seen early in the 

 spring continue through the season, or that those developed in 

 the fall pass unharmed through our severe winters. Those seen 

 early in the season, doubtless, passing the winter in the pupa state, 

 come out about the time the grass starts in the spring, and lay their 

 eggs, which hatch out about the same time with those laid by the 

 fall brood of moths. 



These eggs are deposited on the grass in the low bottom lands, 

 near the ground, "usually," Professor Riley says, "along the 

 inner base of the terminal blades, where they are yet doubled; the 

 ovepositer of the moth is thrust in between vhe folded sides of the 

 blade, and the eggs are glued along the groove in rows of from five 

 to twenty, and covered with a white, glistening, adhesive fluid, 

 which not only fastens them to each other, but also draws the two 

 sides of the grass blade around them." As soon as the weather be-
