Yes it does look like sooby found my bug! I have it quarantined, out in the yard away from other plants. Since I'm not positive what it is, I'm going to test the safer soap spray, make sure it doesn't hurt the cactus, then spray it down. I had the same thing (I think) eating my tomatoes when I first moved to Pensacola; dust didn't work. Hopefully the soap spray will. After examining the plant more closely I noticed something has eaten holes on the underside of one of the newer branches... Sure hope I can save this cactus, I love this thing!
THANK YOU to all who have taken the time to try to help! Much appreciated!!!
