The caterpillars feed during the late summer andbecome full grown in four or five weeks, when they enter theearth for from 2 to 4 inches and there transform to nakedbrown pupae, without making any cocoons. There is but onegeneration in the Northern and Middle States. The species occurs throughout the Northern and Middle Stateseast of the Rocky mountains, and in the far South there seem tobe no records of the species. Though most common on apple, italso feeds on pear, cherry, cjuince, and plum, and on hickory,. Fig. 469.—The yellow-necked applecaterpillar (Da/o«a ministra Dru.):mature larva; and moth—natural size.
