You will have to wait for one of our more seasoned gardeners, I do not have a clue what these are, but I’ll betcha you should be concerned.
I just pick off bugs and squash or spray plants with hot pepper, onion, garlic, soap, oil water mixture.
Yeah, I’m concerned. I don’t know that hot pepper would help since I’ve squished some on the H-O-T peppers though I haven’t seen any damage.
