Both Hawaiian beet webworm (HBW) and beet webworm (BW) have multiple generations per year, and the total number is based on temperature. In tropical and subtropical climates, HBW is active year round, and can complete a generation in about 30 days. The species cannot overwinter in Virginia, but can migrate northward during the season to become a pest in late summer and early fall. BW is found throughout the U.S., but is more common in the western states. This species has fewer generations per year and can overwinter in the soil as a mature larva.
