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.
