The Psychidae (bagworm moths, also simply bagworms or bagmoths) are a family of the Lepidoptera (butterflies and moths). The bagworm family is fairly small, with about 1350 species[2] described. Bagworm species are found globally, with some, such as the Snailcase Bagworm (Apterona helicoidella), settling continents where they are not native in modern times.
