Adult behaviour
The adults are normally encountered singly or in two’s and three’s. They bask on bushes and low herbage with wings fully outspread but rarely spend more than a few seconds in one place. In hot weather they escape the desiccating effects of the sun by sheltering under the leaves of trees and bushes. Both sexes visit flowers, and males also imbibe mineralized moisture from rock faces, pebbles, sandbanks, and the surface of unmetalled roads.
