Alaska/California Week 25


What can I say?  The weather continued to be great and the Steese Highway filled in missing target species like Labrador Sulphur and offered more opportunities to photograph Eversmann’s Parnassian (see below).  Finding butterflies near Fairbanks was a greater challenge as flights may have peaked weeks ago following a very warm May.  Cranberry blues were common, but only one very worn Common Alpine . . . on the last hour of the last day!


Finally!  Back on the road in my comfortable camper Chalcedona, and hopefully no more flights or motels for many months.  Stretching ahead of me is a summer route across the northwest, a quick sprint through the midwest to the northeast, and back to Arizona for the monsoon butterflies of August.  My trek began over Donner Pass for Pacific Fritillary, Hoffman’s Checkerspot, and the dazzling Lustrous Copper (photo below).
