Figure 7. The pupa and cast larval skin of Anisota peigleri Riotte, the yellowstriped oakworm. Pupae, like adults, vary in size according to sex. Male pupae range from 15 to 20 mm and female pupae range from 18 to 25 mm in length. The pupae reside in the soil about 50 to 80 mm deep, "overwintering" for about ten months. Moths emerge the next year to begin the cycle again.
