Found in abundance on Japanese rose Rosa rugosa and plants nearby (in this case, beach grass); common in eastern North America. Unfortunately, this amazing caterpillar cannot be employed as an extermination agent of the invasive rose, since, in addition to the rose, it would consume about anything--as long as it is green, be it conifers, chestnuts, birches, or willows. It belongs to the same family as the infamous LD moth (gypsy moth).
