4 sightings of between 2 and 5 white letter hairstreaks today. 1 settled on top of an elm for a second before flying into a mass of branches on the same tree, two then flew up from the same elm, a couple of minutes later one was seen on top of an adjacent ash tree for around 15 minutes and then one appeared on top of the the elm again. A warning to anybody who might want to look for these I spent at least an hour looking before I found them. All sightings were on the trees that can be mostly overlooked on the north east side of the bridge over the river. Also in the area 12 green veined white, 3 large white, 2 meadow brown, 1 speckled wood and 1 small skipper
