The checklist includes all 717 species of butterflies that have been recorded in North American, north of Mexico, 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. Unfortunately, the checklist is presently out of print. An electronic copy of just the names including typo corrections to the checklist is available at this web site.
