These are green caterpillars with 3 dark spots arranged in a triangle on the side of each body segment. At least one hair originates from each spot. The larvae web leaves with silk, and skeletonize leaves by feeding. This insect is rarely a problem in Minnesota, and has never reached economic threshold levels here.
