Pests in Gardens and Landscapes

Seasonal development
and life cycle

Citrus cutworm has only one generation a year. The grayish adult moth emerges from early January to the end of April, with peak emergence during March. After mating, female moths lay their round, milky white eggs mainly on the upperside of new leaves in clusters of 40 to 225. After a few days, eggs turn dark in color as larvae develop inside; they hatch in 5 to 10 days. Larvae mature in 3 to 6 weeks: the greatest number of larvae is usually found from mid-March to the first of May, but sometimes even later. Mature larvae drop to the ground and pupate in soil. Pupae remain dormant until the following spring.
