Hedylidae, the “American moth-butterflies”, is a family in the order Lepidoptera. The family has traditionally been viewed as an extant sister group of the butterfly superfamily Papilionoidea, but a 2014 phylogenetic analysis suggested Hedylidae was rather a subgroup of Papilionoidea instead, and are more accurately referred to as butterflies rather than moths. The family is represented by a single neotropical genus Macrosoma, with 35 currently recognized species.
