Spun Glass Slug Moth

Isochaetes beutenmuelleri

"Isochaetes beutenmuelleri" is a moth of the family Limacodidae. It is found in the United States from New York to Florida and west to Colorado and Texas. The name comes from the appearance of their pupal stage, when they are very nearly transparent, and covered in spiny hairs containing poison that can cause dermatitis, as is not uncommon for other so-called stinging caterpillars.
