White-letter Hairstreak - Darley Dale

It's been five years since I last heard of a White-letter Hairstreak in Darley Dale but Simon Roddis sent me this photo taken recently in his garden. 
The butterfly clearly still survives in the village but in very low numbers. There are small elms dotted around the local woodlands and these must still support this species.
