Columbia Hills

The long ridge paralleling the Columbia River north of The Dalles is called the Columbia Hills. It is crossed by the Dalles Mountain Road and is loaded with wild flowers this time of year. I spent the afternoon there yesterday and recorded several species of butterflies:

Papilio zelicaon Anise Swallowtail, 3 very faded individuals
White, 1 unknown species (Cabbage White/Becker's White size)
Icaricia icarioides Boisduval's Blue, several dozen fresh males
Glaucopsyche lygdamus Silvery Blue, 2 faded males
Euphilotes species "buckwheat blue," 1 male (couldn't catch, unsure of species)
Callophrys sheridanii Sheridan's Green Hairstreak, 1 plus another green hairstreak which I'm not sure is Sheridan's, could be either affinis or dumetorum.
Euphydryas colon Snowberry Checkerspot, several dozen newly-emerged males and around a half dozen females.
Vanessa cardui Painted Lady, around a dozen faded individuals.
Coenonympha tullia/california Ochre Ringlet, several dozen on the lower slopes.

So much paintbrush!




It really did look like it was glowing!
