Appearance
The large fritillary is fiery reddish yellow above, the basal area of the male being always duller.The markings are constant: a black margin, a row of deep black but thin marginal arcs, a very straight, central row of dots, of which only the last one of the forewing is shifted distad; between this row of dots and the base there are six thin black transverse bands extending from the subcostal vein into the wing.
The underside of the hindwing is characteristic; it bears numerous silver-spots on a partly verdigris partly leather-yellow ground, but never a row of ocelli in the marginal area, as is the case in the forms of the Niobe fritillary and high brown fritillary.
