ABSTRACT. The spatial distribution of the two-coloured bush-cricket Bicolorana bicolor over the Asian part of its range is characterized by the set of known localities for the first time. Abundance levels and general ecological preferences of the species are described. The first Maxent models of the B. bicolor distribution were generated for 3 periods (current, 2021–2040, 2041–2060) and 3 Shared Socioeconomic Pathways. The species is widely distributed in temperate Asia and its populations occur in many applicable habitats (especially in plain and mountain meadows and meadow steppes). In several areas of Kazakh Uplands and the Altai Mts., the species populations may be very abundant. The predicted changes in the B. bicolor distribution are significant and relatively unidirectional. The optimal areas may shift northward and northeastward.
