In the Wikipedia article "Akrida bicolor", my grasshopper is drawn! Thank you all very much!

Externally, all species of this genus are very similar, differences in the details of the structure. Color options, in addition, are the same for many akridas.
Immediately it is difficult to determine the species not only from this photo, but even with a copy in your hand - the genus is very complex, it is confidently divided only into groups of species. I myself gave up on the exact definition of my Asian akridas (except, of course, cinerea, which goes further north than the rest).
Moreover, it may even be Truxalis, another genus from the same subfamily, although they are usually more modestly colored, with slightly different head proportions. But you can only tell for sure by looking at the legs that are out of focus in the photo.

The photo attached to the Wikipedia article was taken in Senegal. It's probably a cosmopolitan species.

If you believe Hartz's monograph of 1975 (after him, no one seems to have considered the European and closest species in detail), then bicolor is widespread in Africa, but it does not enter Europe, and certainly does not occur east of Iran (approximately). In continental Europe (including in our western part of the Hebrew language), only ungarica is found, which is often mistakenly (?) called bicolor. In addition, turrita is found in North Africa and Sicily, and anatolica is found in Turkey, which is often considered a subspecies of either bicolor or ungarica. But again, the differences between the two are very fuzzy.

I wonder how it is with the principle of changing stations

in Pskov region - these are clearings and clearings near pine forests. Related Ps. stridulus species are Myrmeleotettix maculatus, Chorthippus brunneus, Ch. biguttulus, Metrioptera brachyptera, in the last few years - also Oedipoda caerulescens, this year Chorthippus mollis was caught at the same point. In Novgorodchina (near Lake Valdai), the vegetation at the Ps. stridulus collection point is somewhat different - a deposit with sparse herbaceous vegetation. The diversity of erect-winged birds is higher: there are no kopjeuks (M. maculatus), but there are more species of skates: Ch. brunneus, Ch. biguttulus, Ch. parallelus, Ch. apricarius, and among grasshoppers there are Decticus verrucivorus, Bicolorana roeselii, and Metrioptera brachyptera.
