What do you recommend reading about the biology and ecology of polar (tundra) bats?

Regarding tetrixes near the Arctic Circle - I caught from the MSU BBS (near Poyakonda) - T. fuliginosa (recorded a vibration signal), T. subulata, T. bipunctata. Other orthopteroids, except Metrioptera sp. (aff. bicolor) I didn't see it.

Here is still remembered (from their stocks give

), Yakovlev E. B., Lobkova M. P., 1989. Insects. Animal world of Karelia. Petrozavodsk: Karelia, pp. 1-231. (the following species are listed: Blatta orientalis, Ectobius sylvestris, E. lapponicus, Tettigonia cantans, Decticus verrucivorus, Acheta domesticus, Omocestus viridulus, Stethophyma grossum, Chorthippus albomarginatus, Euthystira brachyptera, Podisma pedestris, Forficula auricularia, Labidura riparia, Labia minor).

Let me digress a little and ask: where in Moscow did you meet Phaneroptera falcata? To be honest, I can hardly imagine plate-wingers even in the south of the Arctic Circle.

In the south of M. O.-lives even as. I even took a picture of it there last summer, but it didn't work out very well (I'm embarrassed to scan and post it, but there's no doubt about it). Not to say that it is a common species, but it occurs regularly in all the yugas of the region. And the isophy (I don't know exactly which one-the copy is kept at home, although the color is completely lost) I collected in the Podolsk district. In Moscow (in the southern part - Brateevo or Chertanovo, the valley of the Yazvenka River), there were some impoverished steppe communities in the past, and southern species are found there (although I only know about butterflies). So why shouldn't the fanopter be there?

Barbitistes constrictus, by the way, goes very far to the north, only rarely comes across. For about 15 years of my regular visits to the Novgorod region (Okulovsky and Borovichi districts - in general, the north of the Valdai upland, taiga-type forests, and whether "pseudo" or not-I can't judge), this beast came to me 3 times. Given its inability to fly, it is unlikely that these are migrants. Most likely, it just sits high on the pines and occasionally falls out of there. And there are literary references for more northern points of the Novgorod region (Bey-Bienko gave from the Torbino station of the St. Petersburg - Moscow railway - this is 40 kilometers north). Maybe it goes even further, but we can't rule it out.

More about the Siberian filly. With all due respect to the compilers of the electronic agricultural atlas (I came across this project somewhat from the other side, but tightly), the given area is somehow confusing. So, in the North-West, I have never met it, neither myself, nor in the literary faunal lists (Zubovsky, Miram).

Pseudo-taiga forests differ from taiga very clearly and in very specific parameters: the admixture of broad-leaved species, the floral composition of the lower tier... Barbitistes constrictus is a normal forest species associated with pine, so why shouldn't it be found in Valdai?

to Insect expert: Actually, I'm not so profane in all groups except my own as to consider each wingless blacksmith an isophy of Barbitistes

constrictus, I know, but I didn't immediately remember the name. What I consider an isophy is a purely steppe view. According to the definition tables, I got an isophy. Although I do not claim anything, I could have blundered

Well, that there is not even a photo, but a copy, and there is a real opportunity to transfer it to a specialist. If it is confirmed, it will turn out to be a godsend for the region - you can also publish

2Helene:
Apparently, then not "pseudo", at least, an admixture of broad-leaved species is absent there. But about the fanopter falkat-there is an indication even from the south of the Pskov region (Sebezhsky National Park) - until now I thought that this was a misunderstanding, now I don't think

2Dracus (14). Regarding the power supply of the polar ones, I can't guarantee it. In general, I recall the work of Pshenitsyna and co-authors on the analysis of locust feces. Although without serology, the results will be very approximate. But in any case, it's better than studying what a hungry locust can eat in the bank

.

And yet: in the same monograph of Podgornaya on tetrihids, it is clearly stated that they all feed on detritus, algae, etc., and live higher plants do not eat at all or almost.

An interesting map of the distribution of the Siberian filly is the
link at the top: it is very extensive. And what
will the experts say?

to INSECT EXPERT

Regarding the MSU BBS: in addition to tetrigids, there is also
Chorthippus montanus (in the swamp), and the specimen I
caught should have remained at the department, and
there is a photo of it.

to PVOzerski

The northernmost point where I met M. brachyptera
is in the vicinity of Nyandoma Arhang. obl (near the Nyandomka river)
and M. bicolor is in Rybinsk, on the steep bank of the Volga.

to DRACUS

In the Internet there are links with photos of Phaneroptera falcata
from the Yegoryevsky and Leninsky districts of the Moscow region. If you don't
believe me, I'll look for these links
