Abstract
Sixty one species of grasshoppers
from 35 genera and 8 subfamilies are recorded for
the North-West Caucasus. The features of biotopic
distribution of grasshoppers are analyzed on the main
types of landscapes in the region. In the Kuban – CisAzov
biogeographic province, the highest diversity of
grasshoppers is characteristic of steppe biotopes with
forb-grass vegetation, where 25 species are noted. The
highest diversity is typical for low-mountain meadows and
mountain steppes, which number 22 grasshoppers species
each in the Black Sea – Kuban province. At the same
time, these landscapes are characterized by a low value
of the measure of similarity of Sørensen-Chekanovsky
(0.51). Gramineous chortobionts (52%) and facultative
chortobionts (16%) dominate in the fauna of the NorthWest
Caucasus, the remaining life forms of grasshoppers
are represented by a relatively small number of species.
Among the grasshoppers, seven endemic species for the
North-West Caucasus, as well as two endemic species for
the whole Caucasus, are noted
