Females moths lay black egg sacs on twigs, near a leaf bud so the caterpillars can eat the leaves after they hatch as while they grow.
Adults have dark brown hair and two distinct white lines crossing their wings. Like most moths, they are attracted to lights at night and are nocturnal. They are commonly around roses and fruit trees, like apple, cherry and peach, where they are likely to lay their eggs. Because the caterpillars are feeding off of trees that bear fruit humans like to eat, they may be considered pests.
