The Azure Damselfly can be slightly more localised than other blue varieties. Once located however they can be observed in quite large numbers.
They are best seen in late May and early June when they are at their most active and colourful but can be seen on the wing from late April to early May in a warm spring right through to late August.
The Azure Damselfly can be seen on a wide range of mainly still waters but can also be encountered on the slower sections of rivers and streams. They are often seen at the same sites as other blue varieties however identication is difficult without a close inspection.
In relation to the male, by far the best way to tell blue varieties of damselfy apart is by the shape of the markings on the top of the abdomen just behind the wings on segment two. Each species having a distinct and a unique pattern, the Azure Damselfly having a fine "U" shaped mark which has no stem.
It could be confused with the Variable Damselfly but it has darker markings. Its best to identify the females whilst in the presence of a male.
