Blue-tailed Damselflies are found throughout Britain; they are associated with stillwaters including stagnant and sometimes even polluted ponds.
The eighth segment of the body of both male and female is usually bright blue (although some females lack the blue region), while the rest of the body is black.
The male is shown here, while the female has a green-and-black body colouring. Paired damselflies can be seen flitting over the water surface and dipping down to lay their eggs.
