Wood White

The Wood White is a delicate, slow-flying butterfly usually encountered in sheltered situations, such as woodland rides or scrub edges. The males fly almost continuously in fine weather, patrolling to find a mate, whereas females spend much of their time feeding on flowers or resting. In the characteristic courtship display the male lands opposite the female and waves his head and antennae backwards and forwards with his proboscis extended.
The butterfly has declined seriously in England and Wales. In Ireland it has so far been found only in the Burren, whilst its sister species, Real's Wood White, is widespread and has expanded northwards in recent decades.
