Your letter to the bugman: Knowest caterpillars in my area, but have no idea what this one is. It’s a little bigger around then a pencil.

This is a Prominent Moth Caterpillar in the genus Heterocampa, and there are several similar looking species. These Caterpillars are green most of their lives, but when pupation time nears, they often turn pink or purple, so your individual is pre-pupal.
