features
The animals are 12 to 17 millimeters (males) or 18 to 22 millimeters (females) long. Their body is of a dark red-brown or gray-brown, rarely yellowish basic color. Two dark spots on the hind legs, the black hind knees and the bright blood-red rear rails ( tibia ) are striking . The tympanic organs are oval. In the male, the shortened wings reach almost to the tip of the abdomen , in the female only to the middle of the abdomen.

The species has become very rare in Germany and is only known outside the Alps from the Berlin area and Lower and Upper Lusatia (Brandenburg, Saxony). In southern Bavaria, the insect occurs in the Isar floodplains and the Loisachaue.
Way of life
Adults occur from July to October. The males produce whirring noises of 1 to 2 seconds that sound like a soft, uniform "sssss".
