The moths (mostly nocturnal) and butterflies (mostly diurnal) together make up the taxonomic order Lepidoptera.
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The list has since been updated, but the placement in families is outdated for some species.
This list covers America north of Mexico (effectively the continental United States and Canada).
This is a partial list, covering moths with MONA numbers ranging from 8322 to 11233.
