With news on Saturday evening that there were Southern Emerald Damselflies at Winterton, I took advantage of the warm sunny weather to head down there today to have a look for them. Unfortunately on arrival at the pool in the north dunes, north of the concrete blocks, the area was shrouded in low cloud and mist but glady it eventually burnt off and almost immediately the Southern Emeralds started to appear.
I wasn't totally sure how many were present but I saw three (a male and 2 females) at the same time and ones on their own, plus a pair in tandem on a number of occassions. On the way back at least another two males were seen at the pool to the south of the concrete blocks.
The top 3 photos below are females, with one potentially ovipositing in the third, the fourth pic shows a male, and then a couple of shots of one of the pairs in tandem. The bicoloured pterostigma in the wing being the most obvious field character to identify the species.
