As compared to eastern subspecies, these tend to have smaller silver spots below, dark wings above (toward the base in males, and most of the wing in females). Females often have pale or even bluish coloring where the orange should be above.

The subspecies named letona, charlottii, pugetensis, and eileenae are all very similar, and some authors separate them out as a distinct species under the name of Speyeria leto. However, these intergrade with other subspecies of S. cybele where they meet east and southeastward. They show some differences in pattern, with subspecies near the coast tending to have a narrower submarginal pale band below, but they are best distinguished from one another by where they are found.
