Recent sightings in Sussex
An endemic species is one that is unique to a geographical area, such as an island. Britain has remarkably few endemic species. For most of the past million years Britain has been attached to Europe by a succession of land bridges, which has resulted in it having an overwhelmingly European flora and fauna. The last land bridge disappeared some 8000 years ago.
Eudarcia richardsoni is a micro moth found only in Dorset. It is our sole endemic member of the order of Lepidoptera. There are a small number of endemic subspecies, most notable of which is Papilio machaon Britannicus - the Norfolk Swallowtail. In Sussex we share all our butterflies with the Northern European seaboard and our native stock is regularly enriched by the arrival continental migrants.
