Can someone ID this caterpillar found this week in northern Baltimore County, MD, USA? It was found on a winterberry holly bush (Ilex species). I suspect that it’s a stinging slug caterpillar of some kind, but I can’t find a species that that matches the coloration.

Dear K Smith,
The coloration of the Spiny Oak Slug Caterpillar,
Euclea delphinii, appears to have considerable variation.  This image from BugGuide is quite close to your individual.
