Coordinator notes: This is Queen Alexandra's Sulphur...looks to be a female. The white center disc spot without a pink ring is typical of this mountain sulphur east of the Continental Divide. Scudder's Sulphur has darker green ventral hindwings and a very distinct pink-ring around that disc spot...a fast-flying denizen of willow bogs. Mike
