Description of Limacodidae
The Limacodids are members of the Superfamily Zygaenoidea, and there are about fifty North American species in this family. They are medium to medium-small moths with stout, often hairy bodies, and broad, rounded wings. Most are brown or yellowish with contrasting forewing markings. Adults have small heads, short labial palps, and short or absent maxillary palps and probosces. Typical wingspan is 1.5-4.3 cm. Larvae can be naked or densely hairy, and they usually have stinging hairs. These caterpillars move like slugs, gliding on their prolegs and suckers. They feed on a variety of woody and herbaceous plants and overwinter in loose, oval cocoons.
