Dark Green Fritillary

Plebeius argus

The Dark Green Fritillary is a fast, powerful butterfly, known for their confident flight over sunny, open landscapes. With bold orange wings patterned in black, hints of green above and shimmering silver spots beneath, they are a striking sight. As caterpillars, they begin life by eating their eggshell before hibernating, later feeding on violets. Found across most of the UK, especially in the west, they can even be found as far north as the Arctic Circle.

A restless force of the open countryside

Fast, fiery and fond of open countryside, Dark Green Fritillaries are really powerful fliers that soar confidently through the skies on sunny days. But, despite the strength of their wings, they don’t tend to venture too far from their breeding grounds.

In their youth, newly hatched caterpillars eat their eggshells and almost immediately go into hibernation in curled-up leaves or other plant debris. When not eating shell, they’re known to eat Common Dog-violet and other violet species.

Later, like other fritillaries, they have beautifully ornate wings – intricate black patterns across bold orange with a hint of green on the upperwings and beautiful silver spots on the underwing.

The Dark Green Fritillary is a large and bold butterfly that will patrol large areas of habitat for nectar and potential mates, and they’re not afraid of an early morning wake up to make the most of the sun.

Dark Green Fritillaries are found across most of the UK, but they tend to be more abundant in the west. You can find them in flower-rich grasslands, coastal areas, moorland, and woodland rides. Worldwide, this butterfly can be found as far north as the Arctic Circle!
