List of corrections for Butterflies of the PNW - September 2023

Free PDF file download of the list of errata and updates for Butterflies of the Pacific Northwest by Robert Michael Pyle and Caitlin C. LaBar.

Contains error corrections, taxonomic (Genus/species) name revisions and range map updates (written descriptions not the actual maps).

Last updated September 2, 2023

Note: previous errata list had Papilio switching to Pterourus, and Speyeria to Argynnis. These have been removed for now, per Pelham's 2023 Catalogue revision. There are no other changes to the errata list since the previous update in July 2022.
