Azure damselflies
Azure damselflies are the most commonly seen blue damselfly. These little lines of electric blue are widespread throughout the New Forest and can be spotted in any area near water, especially small ponds, ditches and boggy areas. They also quickly colonise garden ponds. They are also common in the rest of the UK except Scotland.
You do not need to go to any special spot to see azure damselflies: the local pond, a pool on your local walk or even your garden are bound to hold some. The adults fly from May to the end of August. You will see them easily in sunny weather, but if it is cloudy look on the vegetation by the pond and you will probably see some settled there.
