Southern Emerald at Winteron North Dunes

On probably my 4th visit over the years (since 2002) on Saturday 17th August, to twitch a Southern Emerald at the northern most pool at Winterton North Dunes, I followed Murray S's directions and around 150 yards past the concrete tank blocks (a 2 mile plus walk from the former telephone exchange on the northern end of Winterton village) I looked around the pool, then checked the gorse bush just north- west of pool and bingo! the fine female Southern Emerald Damselfly was perched on the northern side of the bush, a new Odonata species for me & she posed well for about 10 minutes. She then moved once then very sadly at 11.25am, when some cloud came over she flew off north- west. Despite searching nearby bushes and the poolside vegetation she wasn't very sadly seen again. She was slightly larger than the normal Emerald the diagnostic feature were the bi- coloured (black/ white) pterstigma on each upper-wing and the swollen rear anal end clearly differentiating from her commoner cousin. Sad to say the right lower wing is almost completely absent apart from its "base", a bird strike? Although I heard from Murray S that she got stuck on a spike (when he was watching her) and had to be set free, so with only 3 wings she may not fly away too far. Lets hope she returns. A great shame there is no male about. Also on the pond were several mating Emerald damselflies, a striking powder blue male Emperor and female Emperor mating at times and many Common Darter with several mating pairs. Also seen around here were 2 Viviparous Common Lizards, one going near the water, the other heading into a gorse bush. I was joined by Steve G from Cley & his wife and neither of us could relocate the Southern Emerald. walking back I checked the southern most Toad pools really good to see Chris L and his wife at the pool with the most water where I saw a Brown Hawker and I checked all the others but alas no Natterjacks were seen. Around 100+ Painted Ladies seen and around 30 Grayling and at times clouds of Migrant Hawkers, over 150+ seen.
