A family of moths characterized by hairy caterpillars, including woolly bears and tiger moths, mostly found in cooler regions.
From Latin 'arcticus' (Arctic) because many species are found in northern regions, combined with the Latin family suffix '-idae' used in biological taxonomy.
In science, every creature gets a special two-part name (genus and species) and belongs to larger groups with '-idae' endings—Arctiidae is a big moth family containing hundreds of species!
