For the south of Central Russian upland,in view of data for last 100 years, 47 species of OrthopteraBrachycera are resulted. Among them 4 kinds, which havedisappeared here for the nearest 50 years, 1 kind living onborder of region, 2 species noted at its external borders. Nowthe fauna of region includes 42 kinds, two of its for the firsttime marked here. Principal causes of negative dynamicsof borders of areas Orthoptera Brachycera in the south ofCentral Russian upland are almost utter annihilation on aplain herb-feather-grass and festuca-feather-grass steppes,significant reduction of extent water-separate plain oakgroves with destruction of pubescent complexes, and alsodestruction of harmed and “potentially harmful” kinds infirst half XX centuries. Anthropogenous xerothermisationof region leads more likely to pauperization of fauna withincrease in a share and number xeromesophilous formsin local communities, than to it steppification. At thesame time, sharply expressed xerothermisation of ironorearea KMA already has led to distribution here typicalsemidesertic species, and deducing from an agriculturalturn of a part of an arable land, haymakings and pastures- to restoration of an area of a flying locust
