Mark and I ventured down to Deepdale at lunchtime today and specifically to a stand of Elms known to support White-letter Hairstreak. Upon arrival, we split up and peered hopefully into the canopy.
Needless to say, I chose the wrong canopy, but M did manage two sightings - one from within the Lodge boundary. We also had good views of Purple Hairstreak (already on the list), Marbled White (ditto) and Brown Argus (still needed for the list).
