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The list has since been updated, but the placement in families is outdated for some species.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: 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 2701 to 3862.
