The following is a checklist of the butterflies and skippers known from the Thunder Bay District. The list was compiled by Dr. Nick Escott, based on his records and those of Alan Wormington and John Walas.
Nomenclature and taxonomy are based on Toronto Entomologists Association 1998. Some species have been added and changes in nomenclature have been made since the original checklist was published in 2000.
This list is current as of October 2019.
