Butterflies of sunny downlands.

The gently rolling downlands of southern England provide a warm and bountiful home for a multicoloured population of butterflies. On sunny days in summer the grassy hills come alive with bright patches of colour as groups of butterflies flutter around their favourite plants. Clusters of blue butterflies, coppers, green hairstreaks and marbled whites sparkle like jewels in the sunshine. The chalk soil of the downs favours chalk-loving wild flowers such as marjoram,thyme ,vetches, knapweed, scabious and yellow carline thistles. And the butterflies reap a harvest of nectar, particularly in warm hollows and on slopes facing south. A butterfly`s, life in the sun is spent establishing territories and fighting off rivals, having minor tussles with bumble-bees and hoverflies, courting and mating, feeding from flowers and basking in the sun. One active common blue might see off half a dozen other butterflies in a lightning chase over the grasses. Fleabane, with its yellow nectar-rich flowers, attracts common blues, small coppers, small heaths and small skippers, especially where the chalk soil is overlaid with clay and flint. Hawthorn, whitebeam,dogwood and spindle bushes provide vantage points for butterflies, such as green hairstreaks, that seek out territories. Where downland meets woodland, sulphur-coloured brimstones patrol the edge of the trees in search of buckthorn and ivy.
