The Green Darner reached wingspans of 8 to 8.5 centimeters. The chest section (thorax ) of the animals is yellow - green, with the side faces are green and not, as in the Autumn Hawker ( Aeshna mixta ) bear a striking line drawing. On the upper side of the thorax they have two large green stains that never are in contrast to the blue-green Darner ( Aeshna cyanea ) really oval, but can look very similar.

Way of life

The Green Darner is to be found in the months of July to October during the stagnant waters of the northern part of Central Europe, including northern Germany. Here ( Stratiotes aloides ) their occurrence is the existence of the crab claw dependent, in which the females insert their eggs almost exclusively. Your hunting flights usually take place at dusk.

In the morning the dragonflies are found in waters close to plants. The males fly in search of a suitable partner on the floating leaves of grass crab claw. Try doing other males, but also other dragonfly species (eg Aeshna grandis) kept away from the spawning grounds. Mating takes place, however, with very high probability the water's edge or on the shore. The females fly in good weather until evening with loud audible wing noise for oviposition between the cancer scissor blades.

Larval development

The eggs overwinter as such, the larvae hatch until the following year. The larval development takes two to three years. The slip takes place in July.



The Green Darner is on the Red List of Germany in the Category 1 - an endangered species - out. The disappearance of the bubble is caused by due to their close ties to the crab claw to the same causes as the disappearance of the plant.
