Scientific name: Argynnis aglaja
A large, powerful, orange and black butterfly. Very similar to the rare High Brown Fritillary, which has an extra row of orange-ringed ‘pearls’ on the underside of the hindwing.
This large and powerful butterfly is one of our most widespread fritillaries and can be seen flying rapidly in a range of open sunny habitats. The males look similar to the High Brown Fritillary, which is far rarer but sometimes flies with them on bracken-covered hillsides. The two can be distinguished from the underwing markings, visible when they are feeding on flowers such as thistles.
The Dark Green Fritillary has declined in parts of central and eastern England but remains locally abundant in western England, around the coast of Wales and in Scotland.

Common Dog-violet (Viola riviniana) is used in many habitats, but Hairy Violet (V. hirta) is also used on calcareous grasslands, and Marsh Violet (V. palustris) on moorland and wetter habitats in the north and west. Other violets may be used occasionally.
