"This exotic insect is of great concern in our state due to its propensity for significant feeding damage to a number of fruit crops, trees, shrubs, and perennials. Winter moth has a broad host range, including apples, blueberries and a wide range of ornamentals.
At this time of year the larvae have moved from within the expanding buds and leaves and are now openly feeding on the foliage. Young larvae feed in and cause severe damage to developing buds on host plants, while older larvae become free feeders on plant foliage, which may cause complete defoliation.
Larvae are pale green caterpillars with a white stripe running down each side of the body. They have 2 pairs of prolegs, which are located at the back end of their body. They grow to a length of about 1 inch. Larvae are expected to be feeding on foliage within the next 2-3 weeks.The larvae will continue to feed until pupation, which will occur in late May or early June."
