The following list shows the differences between the species- and genus-level taxonomies and scientific names of the NABA list and the Opler & Warren list ("Scientific Names for Butterfly Species of North America, north of Mexico", P.A. Opler and A.D. Warren), as updated on February 14, 2003. This page is intended to provide those familiar with one of these lists with a reference to the other. It's worth pointing out that the Opler & Warren list is more recent than the NABA list and also includes some changes based on work that has not yet been published; this explains some of the differences, though not all. Errors in this list are entirely my own, but differences in spelling between the two columns are (all, I hope) based on actual differences between the two lists.

Explanations
"Split [or lumped] from extralimital" refers to species that have been split [or lumped] where the nominate form is not found in North America (north of Mexico).
"Synonym" refers to taxons whose scientific names have changed based on ICZN rules.
"Omitted" and "Considered Dubious" usually refer to species that one or the other list has not yet accepted for the main list. These frequently refer to recent records from Texas.
