Keeled Skimmer; Libélula azul

Orthetrum coerulescens


Dragonfly. Very similat to Orthetrun bruneum. Females and immature males lack the black abdominal pattern. The pterostigma is orange and the thorax usually bears pale stripes. It flies from May to October after having spent in the water, in a state of larva, a period of one to two years. After copulation, the male watches from the shore the laying of the female in the water. If there is an abundance of males in the area it accompanies holding with their tweezers at the end of the abdomen to ensure that no other male will try a new copulation. It breeds mainly in peat bogs. It is common in central and southern Europe. Its flight is quite skittish, with frequent hovering, and it lands often. It can fly quite a distance from water, despite its seemingly weak flight. When it perches, the wings are held forward.
