The Dark Green Fritillary (Argynnis aglaja) is a butterfly of the Nymphalidae family. It is often seen, on pastures and flowery banks, and nearby areas where the preferred foodplants for the larvae, Viola canina and Viola riviniana, grow.
The Dark Green Fritillary uses violets within Bracken mosaics frequently consisting of one-third Bracken and two-thirds grass, often on the edges of suitable High Brown Fritillary habitat. Their distribution can be found on the NBN website.
