The second edition of the checklist includes all 722 species of butterflies that have been recorded in North American, north of Mexico and in Hawaii, giving both English and scientific names.
Space is provided for checkmarks, date and locality information for each species.
Also included is an introductory section, explaining the formation, deliberations, and policies of the NABA Committee on English Names for North American Butterflies, and a commentary section, in which the reasons why particular names were chosen are explained and the votes of the committee are given. A copy of the checklist may be ordered through NABA Sales . An electronic copy of just the names including typo corrections to the checklist is available at this web site.
