Coenagrioninae is a subfamily of the slender dragonflies ( Coenagrionidae) within the dragonflies (Odonata).

features

The Coenagrioninae are small dragonflies with a slender and elongated, almost needle-shaped abdomen and, compared to other small dragonflies, relatively short legs. As with all slender vials, the generally uncolored wings are stalked on the thorax, the length of this shaft is the shortest of all slender vials. The distinction to representatives of other subfamilies is mainly based on the wing veins. In the Coenagrioninae, the wing triangle is short and the anal vein separates from the wing edge near the second antenodal cross vein .

With the exception of some Nehalennia species, the females do not have a protruding thorn in front of the ovipositor on the eighth abdominal segment.

distribution

The Coenagrioninae are widespread worldwide, in Central Europe this subfamily is represented by the species-rich genus of the Azure damsel ( Coenagrion ), the garnet eyes ( Erythromma ), as well as the dwarf dragonfly ( Nehalennia speciosa ) and the early adonis damsel ( Pyrrhosoma nymphula ).
