In documenting geographical variation in butterfly diversity, somearbitrary, practical decisions are made. Diversity, number of species, andspecies richness are used synonymously; little is known about the evenness ofbutterfly distribution. The New World butterflies make up the preponderance ofexamples because they are the most familiar species. It is hoped that byfocusing on them, the errors generated by imperfect and incomplete taxonomy willbe minimized.
