This picture is too dark Make a positive identification.
I think I see a pattern of tiny white spots on it that indicates it is a mourning cloak butterfly caterpillar ( also called spiny elm caterpillar). They do not feed on vegetables, but typically feed on tree leaves.
There is no need to control them, they are ready to develop into pupae and then develop into butterflies.
If you can attach a well lighted picture to this question, please do so.
You can compare yours to these bulletins which have clear pictures of the caterpillar, the pupa, and the adult.
