Almost a miniature purple emperor, this is also a butterfly of the woodland canopy, exquisite in the purple wings of both male and female but requiring a lot of effort to see, and strong neck muscles for gazing upwards for long periods at a time. Its treetop existence means it is often overlooked.
Larval food plant: oak leaves Where seen: high in the tops of oak trees, but not necessarily in woods. It can be found in parks and gardens and even in central London. Current conservation status: stable.
