 Well, aphids don't eat holes in leaves, so we're dealing with something besides aphids. Aphids just attach to the leaf and suck the juice out of a plant. Yeah, this is chewing a hole all the way through. It's a little white organism, probably about maybe a quarter inch to a half inch long, max. I'm not sure what that would be. There's some flea beetles that would cause that kind of damage, but I've never seen any white flea beetles. Well, whatever it is...
