At least I don't think they are, they are similar in appearance, grayish, and will curl around a twig or in a ball when touched but the difference is they crawl up the plant and eat up all the top growth sometimes leaving stems only. This year they destroyed flowers and even did that to my pepper plant and my tomato plant. Anyone familiar with my description without a photo. Sorry I tried to take a pic of it, but my camera blurs when I try to take a close up.
