Similar to but larger and more deeply orange red than Colias myrmidone, the distal margin being more broadly black; on the underside, which is similar to that of C. myrmidone, the very large central double spot of the hindwing is prominent. The female is mostly yellowish white, rarely orange red, bearing small light submarginal spots.
