Coordinator notes: Correct ID...yes...very neat little butterfly (smallest in the world)...is becoming more and more common along the eastern foothills El Paso to Larimer County (very common in the lowlands of western Colorado...my back yard is now full of them...I have several hosts planted they use and nectar sources (dwarf rabbitbrush currently) helps keep them very abundant).
