There are about 12,000 types of North American moths. In comparison, there are about 825 species of North American butterflies. The moths (mostly nocturnal) and butterflies (mostly diurnal) together make up the taxonomic order Lepidoptera.
This list is sorted on MONA number (MONA is short for Moths of America North of Mexico and sometimes called a Hodges number). A numbering system for North American moths introduced by Ronald W. Hodges, et al. in 1983 in the publication Check List of the Lepidoptera of America North of Mexico. The list has since been updated, but the placement in families is outdated for some species.
Former numbers for some species are given in square brackets, for example:
