Green Hairstreak having a good year...?

Green Hairstreak sightings seem to be up this year, with Lucie Bromfield finding one on the Waun in Tonyrefail week before last. Last Monday, Ben Williams then had no less that 34 seen on a tour of Rhos Tonyrefail SSSI open access areas to NE & E of Tonyrefail. I also readily found 5 on bramble just behind the house called "Mountain View" on Cefn Hirgoed, part of Coity Walia common near Bridgend on Friday.
