Life Cycle

One generation. Pupa overwinters in soil or debris. Mature caterpillar present from July to September.

Comments

This caterpillar resembles several other species that eat the same kinds of foliage. The powder moth can be separated from the others by its purplish red subspiracular stripe that usually is most evident on the thorax. The adult of the powder moth flies during both the day and the night.
