features
Construction of the Imago
The animal reaches a length of 31 to 35 millimeters, of which 19 to 24 millimeters are on the abdomen . The hind wings are between 22 millimeters and 26 millimeters long.
The young animal is predominantly brownish, with the brown on the face tinged with yellow. There are two noticeable brown stripes on the brown thorax . The legs are also brown. The wings are transparent except for a shadow and a brown pterostigma . A noticeable brown stripe runs through the shadow at the base of the wings. The parting is black and slightly bulged. The strongly flattened abdomen is brown with a stripe down the middle of the back. With the aging process, the males turn blue.
Construction of the larva
The larvae have eyes located in the center of the face and have a long abdomen that tapers towards the end. The edge of the unpaired front part of the labium , the so-called prementum, is notched. There is also a hook-shaped attachment on segment eight.
Similar species
There is a certain similarity to Erythrodiplax miniscula , but this is much smaller and has no pronounced shadow at the base of the wing. She also lacks the stripes on the underside of the thorax. Erythemis simplicicollis is also missing the stripes, and her face is greenish too .
Protection status
The Libellula deplanata has the protection status G5 worldwide , which means that it is classified as a very widespread and non-endangered species that occurs in large numbers. It received this status on December 30, 1985. In the USA it has the nationally equivalent protection status N5. The eastern states of the USA have also assigned ratings at the state level.
