Description
The Western Pine Elfin (Callophrys eryphon) is a small butterfly with brown wings featuring a band of lighter, irregular markings and a jagged outer edge, often found in coniferous forests, particularly near pine trees, throughout western North America and the boreal north which includes parts of Minnesota. I was never successful in getting photos of one in Minnesota, so the images here are from Colorado’s Front Range.
Range
Only found in far northeastern MN.
