The highest point in the South Downs National Park
Black Down in July
This magnificent butterfly flies high in the woodland canopy feeding on aphid honeydew and tree sap. The males can sometimes be seen at ground level where they probe for salts from road surfaces or from animal dung.
The easiest way to find the nocturnal and well-camouflaged nightjar is to listen out for its distinctive 'churring' call at dusk. The nightjar is most easily spotted at dusk when the males can be seen displaying to females.
The striking black-and-white checks of the marbled white are unmistakeable. The adults can often be seen feeding on purple flowers, such as common knapweed and wild marjoram.
They winter in Africa, leaving our shores in early October and heading as far as South Africa. Males whitethroats build nests out of twigs and roots and the females then decide which to take.
Snakes in the grass
The green and yellow grass snake is our longest snake and can be found across many habitats. During the summer they can be spotted basking in the sun near water.
The secretive woodlark can be hard to spot. It nests on the ground on our southern heathlands and uses scattered trees and woodland edges for lookout posts
