It was found yesterday (17th) by my sister, and she didn’t know what species of dragonfly it was, and duly sent me a photo. I was very surprised to see that it was a female Norfolk Hawker. A record was submitted by myself to irecord.I assume this is pretty recent - Norfolk Hawker in urban Peterborough. The finders say they're going to put it on iRecord which will provide an exact date.
