Overview
The Azure Damselfly has expanded dramatically across the Sefton Coast dune slack system since the 1990s. At Ainsdale NNR's ponds in June and July, Azure Damselflies can be present in hundreds — the brilliant blue and black males resting on emergent vegetation and flying in mating pairs (the 'wheel' position). They're smaller and more delicate than dragonflies, flying weakly but precisely. The dune slack pools are ideal habitat.

Where to See It
Dune slack ponds at Ainsdale NNR. One of the most abundant species at suitable ponds.
Identification
Slender damselfly. Male: brilliant sky-blue with black markings. Second abdominal segment has distinctive U-shape pattern (key feature separating from Common Blue Damselfly). Female: blue or green. Both: weaker flight than dragonflies, lands frequently.
Viewing & Photography Tips
Walk the dune slack boardwalk at Ainsdale in June. Azure Damselflies land on any vegetation near water and allow close approach.

Frequently Asked Questions
How do I tell Azure Damselfly from Common Blue Damselfly?
The key feature is the pattern on abdominal segment 2 (just behind the thorax). Azure Damselfly has a U or cup shape; Common Blue Damselfly has a thick stalk and round 'lollipop' shape. The markings on the other segments also differ. With practice the general 'feel' differs — Azure tends to look more boldly patterned.
