Construction of the Imago
The animal reaches a length of 38-42 mm, 20-33 mm of which is on the abdomen . The hind wings are between 25 and 34 mm long. The Erythrodiplax funera is the largest dragonfly in the genus, followed by the Erythrodiplax umbrata . Their coloring is dark with very different wing lengths which are usually patterned in a strong brown or black. In male animals, the coloration can protrude beyond the pterostigma , but is usually only found shortly before it. The tips of the wings are usually black or brown and the face is also black. The thorax of the males changes from a brownish hue to a black hue as they age, while the females are and remain purple. The abdomen is brown except for rectangular spots on segments 5 to 7.
Construction of the larva
The larva has a hairless body 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.
