Females occur in two colour forms, dark and blue. It has a patchy distribution in Britain, being mainly found in Somerset, Sussex, Kent, the Norfolk Broads, the Fens, Anglesey and south Galloway. It is widely distributed in Ireland. This species needs well-vegetated grazing-marsh ditches, fens, ponds, lakes and canals. Eggs are laid into the stems and leaves of aquatic plants. They hatch after a month, and the nymphs probably take a year to mature. Most aspects of behaviour are similar to the Azure Damselfly. Adults are often found in lush vegetation away from the water's edge. This is a Red data list species in Britain. Sightings
