Both of these species apparently overwinter as adults in North Carolina. Eggs laid on warm days in late winter may hatch into caterpillars during February or early March. Most of these buds turn brown and die. The insects continue feeding as the buds expand and begin to bloom in early spring. Control Although spanworms can sometimes be found by examining buds or flower clusters in early spring, they are cryptically colored and very hard to see.
Cutworms hide under debris or in the soil during the day and are found on the plant only at night.
Infestations are usually recognized by the characteristic feeding damage to buds and flowers. Neither species is usually numerous enough to warrant control measures. To avoid killing pollinators, do not apply any insecticides during bloom. References Cook, W. C. 1920. Cutworms and armyworms.
