HOST PLANT and HABITAT:
Per Jack Harry larvae eat the buds and flowers of Cercocarpus
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
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
Some fed on Cercocarpus
some on Purshia tridentata.
