Status and distribution
This damselfly only started to be seen in Britain on a regular basis in 2000 and was first recorded at the lagoons in 2007, shortly after it was first recorded in Nottinghamshire. It is gradually spreading northwards and westwards. Numbers are small on the reserve and affected by the amount of floating vegetation available.
Best time to see
July and August.
