This is definitely a Stinging Slug Caterpillar in the family Limacodidae, but we are uncertain of the species. The red color is quite unusual. We believe it might be a Crowned Slug Caterpillar, Isa textula, which is pictured on BugGuide, but we cannot locate any images of red individuals. Sometimes caterpillars change colors right before metamorphosis.
