features
Construction of the Imago
The animal reaches a length of 55 to 65 millimeters, 40 to 48 millimeters of which are on the abdomen . The hind wings are between 38 millimeters and 45 millimeters long. This relatively large dragonfly has gray or brown compound eyes and a bright green thorax . The legs on the body are also greenish towards the bottom but increasingly black. The wings are transparent and show a green pterostigma in young animals . The abdomen is also predominantly green, with segments one to three swollen and segments four to seven dark circles. Segments eight to ten are black. The cerci are light yellow or green.
Construction of the larva
The round eyes are arranged laterally at the bottom of the head and the abdomen ends rather bluntly. The paired side plates (ventrolateral plates) of the eleventh abdominal segment , the so-called paraproct , are severely bent at the tip. It has tiny spines on the ninth segment. The larva is hairless except for the prothorax . The head is longer than the thorax with four notches on the lower jaw. The molar tooth formula is (2-4), but always without a molar dam. The third segment of the antennas is the longest. The paired side plates (ventrolateral plates) of the eleventh abdominal segment , the so-called paraproct , are smooth when viewed from the side.
