Distribution and habitat
There are two subspecies. The subspecies L. v. virens is found in the south of the range in Spain, southern France, Sardinia and North Africa. L. v. vestalis is found in the north in northern France, Italy, and across central Europe. It is not found in northern Europe or in the United Kingdom. It is a damselfly of still waters and is found in lakes, ponds, ditches and bogs with abundant vegetation.
Identification
L. virens looks very similar to the other members of the genus Lestes. It has a metallic green body and at rest holds its wings away from its body. L. virens is smaller than L. sponsa. It has a pale brown pterostigma edged laterally with white and its anal appendages are pale to yellowish. L. sponsa and L. dryas both have black anal appendages.
In L. v. virens the yellow line which runs along the humeral suture is unbroken and almost reaches the base of the forewing, whereas in L. v. vestalis the yellow line is reduced and broken and does not reach the forewing. L. v. virens is found in the south of its range and L. v. vestalis is found in the north. The separation of L. virens into two subspecies has been called into question.
Behaviour
The flight period is generally from June to September, but it may start as early as April in the south of its range. L. virens lives in the dense vegetation on the edge of ponds where it feeds, mates, and lays eggs. It is a univoltine species. After mating the female lays its eggs above water on plant stems, the eggs go through a period of rapid development and then enter diapause. They overwinter as developed eggs and then the larvae emerge in spring. The larvae develop very quickly.
