context_page_description: Salisbury Plain is a chalk plateau in the south western part of central southern England covering 300 square miles. It is part of a system of chalk downlands throughout eastern and southern England formed by the rocks of the Chalk Group and largely lies within the county of Wiltshire, but stretches into Berkshire and Hampshire. The plain is famous for its rich archaeology, including Stonehenge, one of England's best known landmarks. Large areas are given over to military training and thus the sparsely populated plain is the biggest remaining area of calcareous grassland in northwest Europe. Additionally the plain has arable land, and a few small areas of beech trees and coniferous woodland. Its highest point is Easton Hill.
context_section_description: The Diptera (flies) include four RDB species which depend on chalk grassland, the picture-wing flies Chaetorellia loricata, Urophora solstitialis and Terellia vectensis and the hover fly Volucella inflata.
