Sighting for June 29, 2013

Rob Santry

Scott Mountain 1 mile east of State Highway 3 at the Trinity/Siskiyou county line.
Siskiyou County, CA

This was a big day for Rocky Mountain Parnassians on Scott Mountain. This is a very localized population that can be found in the high mountains of the Siskiyous and Trinity mountains of Northern California. It is also found in Southern Oregon at Soda Mountain.
Five days ago there were severe thunderstorms that soaked the area. But I had three good, warm days before I showed up and sure enough there were plenty of freshly eclosed Rocky Mountain Parnassians. I’ve included a picture of one individual that is in the process of drying it’s wings. You can easily tell by the yellowish color of the wing, it is still not dry and firm. It Must have eclosed while I was hiking up to the serpentine barrens that contained the Stonecrop larval foodplant.
