With the wings open, the Harris' Checkerspot looks much like the other Checkerspots found in Crex Meadows. A view of the under-side of the wings will allow a positive identification, most notably the row of crescent moon markings on the hind-wing fall along the whole of the hindwing, where on the Silvery Checkerspot, this row is broken for two moon spots above the 3/4 moon spot.

These two pictures are of the same butterfly. I included the picture below because it shows a bit of the upper wings and somewhat how the crescents are very similar from above.
