Butterfly and Hoverfly

This is another version of a photo I already have posted. The photo was taken near Tete Jaune Cache in British Columbia where we were hunting for Lady's Slippers. Both the Hoverfly and the Butterfly were around the flower which I never identified and I managed to get several pictures with them both in focus. The Hoverfly is a Syrphus species which I have not been able to identify further and the butterfly is the Northern Crescent, Phyciodes cocyta.
