|Without seeing them, I can't make an precise identification of the kind of beetle that chewing on your black-eyed Susan's. But the microbial insecticide Spinosad is a low-toxicity insecticide that is effective against many beetles. I'd suggest giving that a try. You could also try the insecticide pyrethrin.
