Euphydryas colon

Observation date: July 10, 2017
Submitted by: shastamax
Specimen type: Photograph
Observation notes: The photos are presumably of different individuals because they were taken at different sites and/or their markings look different. These were photographed over a mile stretch of Forest Service Road 31 near the town of Mt. Shasta, CA. Many of these were in the area, often half a dozen or more at a given site, and one mating pair was observed. Fair weather with temperatures in the 70s F. The area is in a pine forest with lots of blooming pennyroyal and mariposa lily and emerging spiraea.

Coordinator notes: Thanks for the added photos and the locality information. These appear boxier in shape and maybe a tad smaller than chalcedona. I had to spend a lot of time to try and figure this issue out because I am not well familiar with that area, I did spend two days in that area July 8 and 9, 1996 but did not see any Euphydryas on Mt. Shasta itself. I did collect 13 Euphydryas colon wallacensis N of Crater Lake National Park (Umqua River) July 12th that trip but yours may or may not be that subspecies. Not much is published for your locality area-Ken Davenport
