Who’s been nibbling on my stems?

Someone has been snacking on my sungolds — similar chomping on my raspberry canes nearby, but I’m not sure if I have co-occurring evil-doers or if the same beasts are going after both types of plants.

Any suspects come immediately to mind? So I need to get a black light? (Got laid off as a fed so I’d rather not have to buy anything single-use like a black light flashlight .)

Thanks!
