Located females at Strawberry Reservoir, Wasatch County, Utah on  June 24, 2008. 
Elevation 7700 feet
N. 40.09.85, W. 111.11.517

Laid eggs on June  25th and the larvae hatched on June 30, 2008.  These normally hibernate as 2nd instar after turning brown per James A. Scott's Butterflies of North America.  I reared them under 24x7 room light by an east facing window, changed to fresh host plant daily and some of these went straight through to adult butterflies.

Ova
Females began ovipositing on June 25th using the lupine from Strawberry Reservoir.

Larvae
Larva hatched June 30th, photo taken on July 2, 2008.  Larvae fed on lupine from Strawberry Reservoir 23 to 26 days before pupating.
Molted to 2nd instar on July 5th, photo taken on July 6th

Pupae
Butterflies emerged from pupae after about 10 days.

Sub-Species information
"7700' in Wasatch Co. would make them pembina. The borderline between pembina and fulla (ardea) is real fuzzy-  basically,  a 1500 or 2000' chunk of real estate between the deserts and mountain  habitats..."  Andy Warren

Host
Lupine, unknown species from Strawberry Reservoir.
