I decided to stop off at the reserve this afternoon on my way home to look for the Black Hairstreaks again. It was very windy but there were still at least 8+ flying around the tops of the Blackthorns. A few were coming down quite low but soon flew off again. After a bit of searching I finally came across an obliging female sat low down on Blackthorn near the pond. I managed a few shots before she flew off.
Butterflies seen today:-
Small white Black Hairstreak 8+
