The dark green fritillary (Speyeria aglaja, previously known as Argynnis aglaja) is a species of butterfly in the family Nymphalidae. The insect has a wide range in the Palearctic ecozone - Europe, Morocco, Iran, Siberia, Central Asia, China, Korea and Japan.
Description in Seitz
aglaja L. (69b). 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 niobe and adippe.
