One day in the middle of July I made the trip over to Fermyn Woods in Northamptonshire in search of the elusive Purple Emperor Butterfly. It is found in woodlands as well as throughout Central Europe and isolated areas in Britain. Large and dark with white-banded wings. Males have a purple sheen. Females resemble the White Admiral, but have an orange-ringed eyespot under the forewing. They do spend an awful lot of time in the treetops which is why so elusive.
Unfortunately I didn't spot any Emperors but did see some White Admirals which are almost as nice?
