Distribution. Locally from C and S Europe to the Ural Mountains. Outside Europe in the Altai Mountains, Turkey and the Caucasus.

Remarks. Female is brachypterous. There is only a minor variation in the length and shape of forewing of females, and hindwings are always reduced. However, females considerably vary in size, which may give an impression of a variable wing length. Females were collected most commonly early in the morning, while they were active and running among grasses.
