Argynnis niobe
Very similar to the High Brown Fritillary (A. adippe) and the Dark Green Fritillary (A. aglaja), although niobe is usually slightly smaller. The undersides of each of the three species are different and more easily easily distinguishable than the uppersides. In the niobe underside, which is superficially similar to adippe, the veins are usually lined black. The upperside is more similar although thay can be distinguished clearly by the submarginal lunules 5 and 6 that in the case of A. adippe are more flat than the rest.
