Though similar to the high brown and Niobe fritillaries, the dark green
lacks silver-pupilled red post-discal spots on the underside of the
hindwing. The outer margin of the forewing is slightly convex,
distinguishing this species from high brown but not from Niobe. The
butterfly is common in most of Europe but for some reason I don't seem
to have many good pictures of it. I must remedy this in 2006...
