In the south Dr. L. O. Howard considers that there may be as many as six generations a year. In New England the evidence indicates two generations, although possibly there may be but one in some portions of Massa- chusetts, this point not having been conclusively settled. Under these circumstances only a general outline of the life of the army worm can be given. It appears probable that in Massachusetts these insects pass the winter as partly grown caterpillars, which resume their feeding the following spring and upon reaching full size go a few inches into the ground and there transform into dark brown pupae (Fig. 1), in which condition they remain for two or three weeks. At the end of this period the insects have changed to moths which escape from the ground and fly at night, laying eggs for the next generation. The moths (Fig. 1) spread about an inch and a half and are rather uniformly brownish or reddish brown, with a single small white spot near the center of each fore wing above.
