Long Winged Dagger Moth Caterpillar

Dear Virginia Garden Gal,
We suspected this to be a Dagger Moth Caterpillar from the genus
Acronicta, a large and diverse genus with several spiny caterpillars.  We eventually identified your caterpillar as that of a Long Winged Dagger Moth, Acronicta illustris, thanks to this and other BugGuide images.  It appears as though this caterpillar might be capable of stinging.
