LOCATION: On 2 July 2010  two females were  located by Todd Stout at Christmas Meadows Road; East side of Utah Highway 150, .4 miles ESE Stillwater Campground, Summit County, Utah
ELEVATION: 8600 Feet

PHOTOS:
See detail  on title of each photo.  Jacque Wolfe pinned both the male and female.  Notice the male's androconial scales on the upper forewing

LIFE HISTORY:
Two females oviposited  over several days on sedge, the screen on the side of the cage and the tricot material  that covered the top of the cage. One hundred ten ova hatched. Forty ova were given  to Todd Stout who located the females

Ova:  12 days

Larvae:  Variable since  about  half the larvae hibernated at second instar even though they were reared at about 78 degrees and with 24 x 7 lights.  Three stopped eating, walked off the plant, became shorter and wider then formed pupae. Twenty-one sixth instars have not pupated nor hibernated.  They are still feeding but at a slow rate.  Nine larvae that had stopped feeding at second instar began feeding again before they were put into hibernation temperatures and are still feeding as of the middle of October.  They are now last instars.

Pupae:  7 -  9 days

Adult:  Unknown  but I had the adult females for a couple of weeks and they continued to oviposit until the last day.

Broods:  Biennial per "Butterflies of North America" -  James A. Scott. 1986

Hibernation:  Overwinter as  first to third instar the first year and as fourth to sixth instar the second year per "Buterflies of North America"-  James A. Scott. 1986
