Larve on dill.
Found a brownish- black worm ( somewhat like a leach worm)on my dill. I want to attract swallowtails but didnt show this worm. This pic is the best I can do. Hopefully it can be identified. Thank you for your time & knowledge.
It's definitely not a swallowtail. My best guess is that it's a cutworm. They're bad news and should be treated.
