Welcome to Butterflies of America

a website devoted to the study and enjoyment of American butterflies.

Currently, we show 160,500 images and list over 8,300 species, and these numbers are growing every day. Our aim is to develop a comprehensive online resource that will include information on taxonomy and identification, distribution and habitat, life history and bibliography for all butterfly taxa in America, including species, subspecies and undescribed geographic variants.

Introduction — Meet the authors & advisors and learn more about the website
All-America pages — Covers North and South America - many type specimens
Interactive List — Covers Alaska to Panama, Hawaii & most Caribbean islands
Catalogue — Interactive synonymic catalogue (United States and Canada)

 Note: This website is a constant work in progress. We try our best to provide the most accurate information, however, errors inevitably creep in and are the responsibility of the authors, not advisors or photo contributors. If you suspect that some identifications are not correct, please contact one of the authors.

 Many photographs of specimens (except type specimens) have been digitally edited to eliminate imperfections that detract from the features important for identification and visual enjoyment of images.
