©Nicky Davis LOCATION: Nicky Davis, Les Davis and Jack Harry located female 28 June 2012, 5.5miles SE of Orem, 1 mile East North East of Squaw Mountain, Utah County, Utah Females were nectaring on yellow and white flowers in the area We returned to the same location 2 July 2012 for more photos and the behri were nectaring on the same yellow plant. GPS - N. 40.16.559, W 111.36.025 ELEVATION: 7541 feet 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.
