Dear bug whisperer,
BugGuide lists Beutenmueller’s Slug Moth Caterpillar, Isochaetes beutenmuelleri,
as uncommon.  It is also known as the Spun Glass Slug Moth and caterpillars feed on swamp oak leaves.  Many of the caterpillars in the Slug Moth Family Limacodidae are capable of stinging, but we are unsure is this species has the stinging spines.  Your photo indicates that it probably does.
