Hi Dave/Phil,
An interesting thread, but it may be worth clarifying a point of possible confusion. Bentley Station Meadow is adjacent to Alice Holt Forest in the north of Hampshire. Bentley Wood, still a good site for Purple Emperor, is about 40 miles away on the Hampshire/Wiltshire birder. For details of Hampshire sites, Alan Thornbury's butterfly website is excellent and the Hampshire branch of Butterfly Conservation gives details of recent sightings of Purple Emperor.
Good luck
Dave W
