Common Darter Dragonfly
The Common Darter Dragonfly can be seen on the wing all year round in southern Europe but in northern regions they occur from June to November. This small Dragonfly is seen in a wide variety of habitats, including lakes, ponds, canals and slow-flowing rivers. They are ambush predators, waiting on a prominent perch – such as a leaf or the top of a gate, until prey fly past, whereupon they will fly after it. They are territorial on breeding waters, often attempting to chase much bigger Dragonflies away. This habit of repeatedly returning to a sunny spot allows you to easily predict where they are going to land, which is why it is one of the easiest dragonflies to photograph. In suitable hunting areas away from water, however, they are not territorial: large numbers may assemble – groups of several hundred in a single field have been recorded – and lines of insects can be seen along the top of field gates. Eggs are not laid, but broadcast from the air, the male Common Darter Dragonfly holds the female in tandem and swings her down and forward over water at a height of around 40 cm. At the furthest point of the arc the female releases some of her eggs to fall on the water.
