I wouldn't have believed it, but I caught it myself today. Meeting point-Okulovsky district, Yablonovka station on the St. Petersburg-Moscow railway line. A male Locusta migratoria flew straight to the vegetable garden, where I was peacefully digging potatoes. It's been a long time since I've jumped over fences chasing insects

Photos taken "in hot pursuit" are attached. I apologize for the quality.

Regarding locusts near Biysk - you can view the map: http://www.agroatlas.ru/pests/Metadata/Met...gratoria_ru.htm I have the impression that Biysk falls within the locust range (although, of course, Agroatlas maps are not the most reliable source (judging by their own range of the Siberian mare).

And I was finally able to measure my Novgorod copy. According to the indices given by Bukashechnik, the transition phase really turned out (although according to the indices from Beybiyenko and Mishchenko 1951, it turns out to be herd-like - only the color is not the same). In connection with my desire to publish a short message, a question to Izbasar and to all people of good will

: what is the source where these E/F and F/C indexes are published?

In 1921-1924, there was a "catastrophic outbreak" of mass breeding of Asian locusts in the TASSR, followed in 1935 by separate outbreaks of locust in Mordovia and the Samara region. In 1939, G. Ya. Beybiyenko discovered again 8 copies. locusts in Tartary and came to the conclusion that there are permanent nests of Asian locusts. In 1939 and 1940, local locust outbreaks were again recorded in some regions of Tatarstan. In fact, to test this hypothesis, M. M. Aleynikova began studying the "locust issue"in Tatarstan. Its main conclusion: Tatarstan is a place of permanent reserves of Asian locusts, the largest ones are confined to the left bank of the Volga (Zavolzhye). Individual foci were found on the right bank of the Volga River (the territory is favorable for the occurrence of foci). The main foci are confined to the upper terraces of the Volga River. The eastern border of the distribution of Aleynikova is drawn along the left bank of the Kama River. The northern limit of harmfulness was tentatively established by S. A. Predchetensky (1935) along the Cheboksary-Malmyzh line.
According to biometric parameters(size, sexual dimorphism), locust specimens studied by M. M and Aleynikova are typical representatives of L. m. rossica Uvarov & Zolotarevsky 1929.

About the number of specimens: I still have about 10 Asian locust imagos. The actual number of copies available to M. M. Aleynikova was much higher (only for obtaining biometric data, she measured 569 copies over three years). I apologize for the inaccuracy in the previous report, M. M. Aleynikova's Locusta is listed as Locusta migratoria danica (Linnaeus, 1758), i.e. as far as I understand it, it is a synonym for L. m. migratoria. As for the independence of L. m. rossica Uvarov & Zolotarevsky 1929, this seems to me to be a controversial issue. Previously, the Central Russian locust was singled out as a separate subspecies. Now someone highlights someone does not... Somewhere it is still written that "in the forest-steppes and in the south of the forest zone of European Russia, the subspecies L. migratoria rossica Uv. et Zol." is widespread . http://www.agroatlas.ru/ru/content/pests/Locusta_migratoria/
http://www.fao.org/ag/locusts-CCA/ru/1010/...1078/index.html

Some consider L. m. rossica to be synonymous with L. m. migratoria http://orthoptera.speciesfile.org/Common/b...xonNameID=51999

there is also a division into such subspecies http://zipcodezoo.com/Animals/L/Locusta_mi...ria_migratoria/

By the way, E. H. Zolotarev (1936), who studied Asian locusts in the Middle Volga region, comparing specimens from the Samara region with more southern specimens (size, degree of sexual dimorphism), came to the conclusion that Asian locust specimens from the Middle Volga region (Kuibyshev region) in terms of its parameters, it is more relevant, the quote "to the southern than to the northern type of it". It is also interesting that Aleynikova notes that the Asian locust from the Kuibyshev region significantly exceeds the size of specimens from Tatarstan, but the latter are still somewhat larger, for example, specimens. from Mordovia. In her opinion, the decisive sign for the separation of two ecological and geographical races (according to Predtechensky, 1928) is the hip index. There were transitional instances between two ecological and geographical races (which, in my opinion, is interesting).

..Miracles, discuss the Middle Volga region and again about the Penza region silence...
Based on my more than twenty years of observations of the insect fauna of the region, I can safely say that the "Asian locust" was, is and will be in suitable biotopes of the Penza region. I've seen and caught enough of it. The color varies from gray to poisonous green. Very successfully it can be caught on the forest edge or the edge of a cornfield, for example... Kulig didn't even see the migration phase. Everything that the mass media reported about locust outbreaks in our region this year-everything refers to prus in Italian ("locust" is the local name of prus. I suspect that under the fight against it, funds were knocked out of the state budget)! I've seen him around the south pretty well this year. For the dedication of the masses, I caught all the big pryamoptera in August and arranged a performance on local television - let people know what kind of locust it is! And most importantly, what are the "green" grasshoppers-and then crush them all who are not lazy with screams - " LOCUSTS!!!". To do this, they even recorded a story in a local TV program for gardeners and gardeners. I think that this action saved a huge number of green and singing grasshoppers from certain death...
By the way, who feeds the birds in the winter - I successfully collect and dry very large Italian prusov-in the winter I feed the birds...

It is possible that information about the migratory locust of the Penza Region can be found in such rather old sources as:
1) Zolotarev E. Kh. On the Asian locust (Locusta migratoria L.) of the Middle Volga region / Byull. Mosk. Probytat Island. nature. Department of Biology, vol. XIV, v. 4, 1936 b.
2) Predtechenskiy S. A. Locusts in Central Russia. Izv. Otd. prikl. entomologii, 3/2, 1928
3) Predtechenskii S. A. Prakticheskie rezul'taty ekologicheskogo izucheniya locusts v Srednoi Rossii [Practical results of ecological study of locusts in Central Russia]. rast., Ser. entomologich., Vol. 1, V. 1, 1930 a.

I wasn't particularly interested in this question. As far as I can remember, the Penza Region was never mentioned in M. M. Aleynikova's research (taking into account her analysis of literary sources).
Predtechensky, in his 1928 publication, points out that in the 1920s there was a massive breeding of migratory locusts in the Tambov (herd phase), Ryazan "and adjacent regions" (the so-called foci of the northern race) ,as well as in the Kursk and Bryansk regions. In 1891-1893, migratory locusts were recorded in the Nizhny Novgorod region (Predtechensky, 1928; Stankov, 1938).

Approximately 3-5 years after the mass breeding of migratory locusts in Tatarstan (1921-1924), I. F. Bayryshev wrote about the presence of migratory locusts, Italian prus and other pests in the Penza region (1927; 1930). I am not familiar with these publications in detail. However, it can be assumed that within a few years after the emergence of a hotbed of migratory locusts in Tatarstan (in 1923 it penetrated the eastern part of the republic), it spread much further south to the Ulyanovsk and Penza regions.

M. G. Sergeev and co-authors in " Locusts of Kazakhstan, Central Asia and adjacent territories adheres to the traditional point of view on the existence of L. migratoria migratoria (L.) and L. migratoria rossica Uv. et Zol.
However, there is an interesting reference in the book-an alternative opinion of foreign researchers: Farrow & Colless d. h., 1980. Analysis of the interrrelatioships of geographical races of Locusta migratoria (Linneus) (Orthoptera: Acrididae) by numerical taxonomy, with special reference to sub-specialisation in the tropics and affinities of the Australian race. Acrida 9: 77-97
Unfortunately, on the Web, I did not even find the abstract of this article... But I think the ZIN RAN library should have one...

I specifically raise the topic - since locusta finds in the Central region of the Russian Federation are now being actively discussed in the" definition of erect wings". I think it would be more appropriate here.

Yes, Pavel I understood that. Simply and there it is necessary to answer

.
I post my post from there here.
Locusta migratoria was observed by me several times (all the time singly) in the city of Zheleznodorozhny, Moscow region and its environs in August-September 2000. And this year, a person writes that she is already in packs with us (it would be interesting to listen to a clear story because I have not personally seen her since the memorable year, although it is difficult not to notice such a filly)

I want to bring a photo of the herd phase (the capture point is on the map).
A particular specimen was caught directly in the city on September 19, 2000, in a swamp at the source of a small pond.
Many thanks to DanMar and kotbegemot for explaining the phasicity of the instance shown in the pictures.
P. S. There are also 3 more copies in the collection. since that year, and one of them is still a single phase (I'll post it later).

And I saw 1 copy in the fall of 2010. in Alpatievo, Lukhovitsky district, Moscow region. Unfortunately, he flew away from me =(

it is about fishing: I walked along the highway with metal bumpers (this is important) and, picking up the animal, tried to drive it directly to the roadway, preferably at a right angle; sooner or later an insect with a terrible ringing (surprisingly, it just cuts off, the head is intact) rams the bump and falls, here you need to hurry and grab! mostly, it worked. and what is interesting - only a few flew under or over the bumpers, whether it was an accident or not-I don't know, but most of them hit exactly in the center, "in the bull's eye". if you are interested in the place-a suburb of Kaluga, planting fodder corn, about the first half of two thousand, then, like, disappeared, but last summer in the same places I found one crushed ...
