White-marked tussock moth ( Orgyla leucostygma , Lymantriidae) is common in eastern North America. Unfortunately, this amazing caterpillar cannot be employed as an extermination agent for Japanese rose, because in addition to the rose, it would consume about anything, as long as it is green, be it conifers, chestnuts, birches, or willows... Indeed the caterpillar belongs to the same family as the infamous gypsy moth! Photographed on beach grass (but hopefully interested mostly in the rose) — Photo Alexey Zinovjev [41.96827 -70.64436] [acme mapper]
