[Insects of the Columbia River Gorge of Oregon and Washington]

Butterflies of the Columbia River Gorge of Oregon and Washington

Cedar Hairstreak

Cedar Hairstreak: Mitoura grynea barryi/nelsoni

The following list is approximate. I've viewed records displayed in "An Atlas of Oregon Butterflies" by John Hinchliff to compile this list, but because of the scale of the maps viewed, I can't always vouch that some of the species listed may have been verified from areas more than 5-10 miles north or south of the Columbia River itself. The list is just a starting place to examine these beautiful creatures more fully in the Gorge.
