Though over a score of species are common, it is not practica-ble to distinguish them in this discussion, and though their lifehistories are somewhat different, they may be considered as a class. The adults are moths with dark fore wings, variously markedwith darker or lighter spots and narrow bands as shown inFigs. 52-59, and with lighter hind-wings, which are folded overthe back when at rest. Like the cutworms, they feed at night,sipping the nectar from flowers, and are known as owletmoths. The females deposit their eggs in grass land or wherea crop has been allowed to grow up in grass and weeds in late.

The next spring they arc exceedingly hungry after theirlong fast, and attack any vegetaton at hand with surprising vorac-ity. If the land is in grass or weeds they have plenty of food,and if it is th(>n plowed and planted in some crop, it willcertainly be injiucd.
