ABSTRACT. Investigations of night activity and trophic behaviour of Mesobuthus eupeus (C.L. Koch, 1839) were carried out in semi-arid habitats in the eastern part of Azerbaijan. A trimodal character of night activity and homing in adult specimens of scorpions was noted. Young specimens had an unimodal rhythm of night activity, and after staying on the surface did not return to the old shelter, each time exploring new areas. The absence of homing in young specimens may contribute to a more equitable distribution within the territory. The longest night activity was detected in adult males. The strategy and tactics of trophic behaviour of the scorpions was determined by peculiarities in the landscape, and by the size and movement of their potential prey.
