Male - Dorsal Photo Details - ©Nicky Davis LOCATION: Male specimen located by Jim Reiser at Deerfield Reservoir, Pennington County, South Dakota, 2 July 1997.  Photographed from the Jack Harry Collection. GPS:  unknown ELEVATION:  unknown After coming out of hibernation, they were given Astrgalus cicer  which they fed on for some time but then lost interest.  I tried them on willow which they refused.  I also tried them on Thermopsis montana which they fed on a little.  I was not able to get more of this plant because it all died due to weather. Therefore, the larva that was left could not make it to pupa and it died. LIFE HISTORY: Ovum:  ? Larva: ? Pupa:  ? Adult:  ?
