Most identification guides can only show a couple small photos of each species. It is helpful to have additional views, especially where there are differences between the sexes or regional subspecies. Listed below are selected common butterfly species found in Oregon. Click on a highlighted species name to see various photos of that butterfly. The list will grow as photos of other species become available.
I generally follow Pyle's Butterflies of Cascadia for the English and scientific names as this is the primary guidebook for Oregon. I try to cross-reference with the standardized names used by NABA or other authors where they differ (see references). Unfortunately there is considerable disagreement on several species.
