Explanation of Names
Family name Limacodidae is from Limacodes (author?), which was a genus name for a number of species in this family, but is now (apparently) no longer in use. That from limac/limax a snail or slug, plus suffix -odes form (2). This clearly refers to the caterpillars.
Common name is for the caterpillars, which move with a slug-like gliding motion.
