ECOLOGY. The species commonly prefers different variants of the dry steppes on the local piedmont plains and river terraces with dominance of grasses ( Stipa L. and Festuca valesiaca Schleich. ex Gaudin ), sagebrushes, some forbs ( Potentilla acaulis L. etc), and often with presence of Caragana Lam. bushes and stones. Sometimes it may inhabit meadows and agricultural fields. The level of its abundance is relatively low (up to 12 per hour).
