White Admiral Pupa.

Following the sighting of a second generation of White Admirals on the Isle of Wight earlier this month(see blog entry of the 15th September) what better time to show a photo of the butterflies' pupa or chrysalis stage.
The pupa is typically formed upside down suspended under a leaf or the stem of the foodplant and secured by the cremaster.It is a very unusual shape with two prominent horns on the head and a curious protrusion at the back.This stage lasts two to three weeks.
