HOST  PLANT and HABITAT:  Per Jack Harry larvae eat  the buds and flowers of Cercocarpus ledifolius.
In "Butterflies of North America" Scott shows the host to be leaves of Cercocarpus montanus.
In "Life Histories of Cascadia Butterflies" David G. James and David Nunnallee lists Purshia tridentata as the host plant and report that the young larvae fed only on buds but switched to leaves when they were half grown.
When I reared  Behrii  the young larvae ate through the sides of the flower buds. By the time they were third and fourth instars they fed on flower petals.  None of them ever fed on leaves.  Some fed  on Cercocarpus ledifolius and some on Purshia tridentata.
