features
Construction of the Imago
The animal reaches a length of 50 to 62 millimeters, of which 37 to 42 millimeters are on the abdomen . The species is therefore relatively large. The species has a light face that, like many other species, changes color and becomes darker with age. The thorax is brown and yellow in females and not yet colored males. The males turn darker with age and take on a grayish tinge. The wings are transparent except for a white shadow at the base and a black stripe at the edges. The hind wings are between 41 and 49 millimeters long.
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 smooth.
