Hedylidae, the "American moth-butterflies", is a family of insects in the lepidopteran order, representing the superfamily Hedyloidea. They have traditionally been viewed as an extant sister group of the butterfly superfamilies Papilionoidea and Hesperioidea. In 1986, Scoble combined all species into a single genus Macrosoma, comprising 35 currently recognized and entirely Neotropical species, as a novel concept of butterflies.
