Construction of the Imago
The animal reaches a length of 54 to 59 millimeters, 32 to 39 millimeters of which are on the abdomen . The species is colored bright red on the face, on the front of the thorax , on the abdomen and on the abdominal appendages . Seen from the side, the thorax is brownish with a slight tinge of red. Furthermore, it has no patterns. Young animals, on the other hand, are reddish-brown with a yellow stripe along the top of the abdomen. The hind wings reach a length of 35 to 47 millimeters. On both wings of the males there is an amber-yellow shadow at the base, which extends to the wing triangle . The wings of the females are transparent. The pterostigma is brown and about 6 millimeters long. The legs are brown and have black bristles. The eighth abdominal segment is significantly widened in females.
Similar species
The Libellula croceipennis looks similar to L. saturata , although the pterostigma is always shorter than 5 millimeters. The wing coloration is also more pronounced in L. saturata and extends over the nodus . The species L. needhami and L. auripennis can be distinguished from L. croceipennis in that they have a black stripe along the abdomen. Dythemis maya , which is easy to confuse, has a much slimmer thorax.
Construction of the larva
The larvae have eyes located in the center of the face and a long abdomen that tapers towards the end. The edge of the unpaired front part of the labium , the so-called prementum, is smooth.
