Hamearis lucina
In 2003, only eight Duke of Burgundys were recorded in Sussex, and this species was rapidly heading for local extinction. A major conservation initiative was launched by Neil Hulme, and with the help of a large band of volunteers, and the sympathetic support of many landowners, this precipitous decline was reversed. In recent years, the county total has run into the high hundreds and this species is now doing very well. All the breeding colonies are found on downland and mostly in open habitat, but there are a few small colonies in a more woodland setting.
Given a decent view it is a relatively straightforward ID. The uppersides of the male is a 'burnt orange' and this is overlaid with a complex pattern of dark brown bars and stripes. The female is similar but is noticeably larger and the background colour is a brighter orange. The undersides of both sexes are similar and made up of a lovely mixture of browns and yellow ochre, with two parallel rows of pearly-white dots on the hindwing.
The first adults emerge in late April or early May and the flight period extends until around mid-June.
There are now many locations in Sussex to see Duke of Burgundy, and they include Kithurst Meadow at TQ070125, Chantry Hill at TQ0812, Fairmile Bottom LNR at SU986091, Harting Downs at SU796185 and Heyshott Escarpment at SU899168.
