George T. Austin [1943-2009]
George T. Austin, prominent Lepidopterist and Scientific Advisor to Butterflies of America, passed away on June 30, 2009, in Gainesville, Florida. Among Lepidopterists, George is best known for his work on western North American butterflies, where he described dozens of subspecies, as well as his work on all Neotropical butterfly families, especially the skippers (Hesperiidae) and Calephelis (Riodinidae). If you would like to learn more about George and his work, please visit his memorial page.

In the interactive list presented herein, family-, genus-, and species-level nomenclature generally follows Pelham (2008) and/or Opler & Warren (2002, 2005) for taxa occurring in the United States and Canada, Smith et al. (1994) for Caribbean taxa, and Warren (2002), Lamas (2004), Mielke (2005), or recently published studies (e.g., Wahlberg et al. 2005, Brower et al. 2006) for other Neotropical taxa, with few exceptions.  All cases that differ from these sources, as well as undescribed taxa indicated in the list, will be elaborated upon in future publications currently under preparation by the authors of this list and their colleagues.  Scientific names used herein strictly conform to the mandatory provisions of the International Code of Zoological Nomenclature (ICZN 1999), with one exception.  The provision in the Code requiring agreement in the gender of species-group names (when they are not or do not end in a Latin or Latinized adjective or participle in the nominative singular; see ICZN 1999: 38, article 31.2.1) with that of the genus-group name (ICZN 1999: 38, article 31.2, p. 43, article 34.2) has not been followed.  For a complete discussion of why the application of this provision is impractical and problematical, see Sommerer (2002) and Lamas (2004).  Therefore, in cases where the status of emended names is questionable (see ICZN 1999: 39-43, articles 32 and 33), the original orthography of names is used herein.  Use of the word “Complex” after a species’ name indicates that more than one species is apparently represented by that name, yet relationships of the undescribed taxa remain poorly understood.  Unlike scientific names, where rules dictated by the ICZN govern the use and application of all names, there are no rules governing the use or application of English, “common,” or “vernacular” names, and such names have no formal taxonomic standing.  Common names used herein are taken mostly from Warren & Llorente (1999), Brock & Kaufman (2006) and Warren et al. (2008), with new names coined for many Central American taxa.   

The current listing includes all species, subspecies, and distinctive undescribed segregates known to the authors to occur on the North American continent, from Alaska through Panama, Hawaii and the Caribbean islands (excluding Trinidad, Tobago, and islands off the Venezuelan coast).  Since our knowledge of the butterfly fauna of Mexico and Central America remains largely fragmentary, we anticipate frequent additions of Neotropical taxa to the list over time.

This web-site is a constant work in progress. We try our best to provide the most accurate information available to us, 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.

Most 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.

You will also want to visit the Electronic Reference Library for downloadable scientific papers in PDF format.
