Saturnidae

Emperor Moth

Saturnia pavonia

female - Jura, Argyll, Scotland - May 2008

Female Emperor Moths generally fly at night but can occasionally be found during the day when they are at rest, as was the case with the above individual.  Males, on the other hand are most active by day and can often be seen quartering over moorlands and heaths in search of females.
