Purple Emperor Butterfly

Rare butterfly is being protected at Alice Holt Forest

APATURA IRIS .  Male purple emperor on Salix caprea .  Location: Alice Holt , Hampshire , England .

The Purple Emperor is one of Britain's most elusive butterflies, and we are privileged at Alice Holt to have the highest recorded population of these rare creatures in Hampshire.

 The butterflies rely on our forest’s large blocks of broadleaved woodland and dense scrub with its good supply of willow that provide ideal breeding habitat.

Our ongoing native woodland restoration work at Alice Holt Forest is helping to expand the wet woodland, which will create the right conditions to safeguard the butterfly’s habitat. We want to see this vital colony of butterflies thrive here and hope that visitors might catch a glimpse of these beautiful creatures this summer.
