This larva, not a caterpillar, is difficult to identify. It is a sawfly larva, not one of a butterfly or moth, because it has more than 5 prolegs, the stubs running down the length of their bodies. One was photographed very near Dogwood (Cornus drummondii) which is a known host plant to this species. We also got help from the volunteers at BugGuide.
The abundance of this species in Fontenelle Forest and Neale Woods is not yet known.
