"... the silvery checkerspot has broad black margins and bases to its orange wings ... [and] Some black spots in submarginal row above and below have white centers."

This is the ventral side.

The Silvery Checkerspot and the Pearl Crescent are very close in appearance ... so much so that I had originally identified this butterfly as a Pearl Crescent.
