Parietal fovea You have correctly identified smile.gifthe Genus-indeed, Omocestus. I can't go any further, because in nature I only dealt explicitly with other species.

There is a suggestion ( request) - try to record their signals in the next field season, if you are in those parts again. Any household recording equipment is suitable, up to a portable voice recorder. About 10 years ago, I saw such analog devices in all sorts of stalls with Chinese consumer goods (and more reliable ones in audio-video stores). True, I attached Soviet microphones from kits to large reel-to-reel tape recorders. He would sneak up close and write directly in the field. You can, however, record indoors - even directly on the computer - but in no case from a glass jar. Then a gauze cage is made on a wire frame and screened from the sides with pieces of cardboard cellular egg boxes.

Yes, it is clear that you will have to buy a voice recorder and go back to the Voronezh
Region in August.
Well, how can you determine by such a key ?

26.02.2012 12:23, PVOzerski

Yes, defining keys are not always good - what is, that is. There are worse things, up to outright mistakes. Here, of course, the determinant is very lacking in figures.

26.02.2012 12:33, Olearius

In the same definition,it is indicated
that Horthippus albomarginatus should have an S-shaped curved
radial vein.

Here is a drawing there

picture: Untitled_1.jpg

But this is the specimen that was determined before the albomarginatus group.
The wing is enlarged.

picture: Albomarginatus_wing.jpg

There is no S-shaped bend.
How can this species (albomarginatus s. lato) be distinguished from similar species
with a similar pronotum structure ?

26.02.2012 12:49, Olearius

And again, back to Omocestus.
The very phrase "parietal fovae are brought together in front"
"parietal fovae are placed in front"is not clear

Here are the parietal fovea of these Omocestus.

If they are close together, as the arrows in the figure show,
then this is minutus,

picture: Yamki2.jpg

if placed as the arrows in the other picture show,
then petraeus.

picture: Yamki1.jpg

26.02.2012 13:20, PVOzerski

I'll put it this way: your filly doesn't look much like petraeus - at least not like the locusts that are listed under this name on the Internet (including collectible specimens from museums). The impression is that petraeus is a very stocky filly, somewhat similar to Myrmeleotettix maculatus. But, in general, you need to look at the collections and compare songs.

So I'm back. Is it possible to accurately determine the type of Prussian from these photos?
2_017, 2_018, 2_019 - Turkey, Alanya, June.
The rest - Astrakhan, August.
2_017 the smallest, male?

This is not an erect wing, but a cicada. I can't be more precise.

19.03.2012 19:16, PVOzerski

Something about Prussia:
In my opinion, the first 3 photos are C. italicus, the 4th - C. barbarus barbarus, the last 4-C. barbarus cephalotes. Naturally, the "nominativeness of the subspecies" of a single individual of C. barbarus, in which the darkening of the thigh is divided into bandages, is conditional.

Hello,
Help the PJ to determine if it is not difficult
All the photos were taken in the vicinity of Krasnaya Polyana, July 13 and 17, 2009.

1. Oedipoda? Can we assume that caerulescens or maybe some other?
user posted image

2. Acrida, obviously. bicolor? or is there anything else in those parts?"

3. Metrioptera bicolor, right? is she short-winged or just not quite grown up yet?

20.03.2012 14:05, PVOzerski

"Metrioptera" is actually the larva of some long-winged species from the genus Platycleis. Don't let the green color bother you: it will disappear in the imago.

We have already written a lot about the problems with the akrid species, in the same topic. So they are unlikely to be identified reliably by imago, and then there are larvae. And in general, determining locust larvae to a species is a task that is feasible only in some cases. I wouldn't take it in the case of acrid or oedipus.

Thank you very much!
I really first got Platycleis by the determinant, but the color confused me.
With the rest of the sawyere is clear and thank you for confirming the birth.

Please advise which phase of Locusta migratoria (herd or solitary)
it was caught on September 19, 2000 in the city of Zheleznodorozhny near Moscow? I'm being a bit blunt about this. Put a point for a specific instance on the map:

It seems that the pronotum has a herd shape, the middle keel does not bulge..
"The median keel of the pronotum in a single phase is characteristically curved (in the herd it is low, almost straight)"

Thanks! Just now I decided to sort it out completely. In the memorable year 2000, a small series of this unusual animal was collected. It was caught singly from different points far from each other in the vicinity of the city. So I did get there.

I join the locust issue: 2011. the city of Dolgoprudny. Herd or solitary? Maybe these are different subspecies altogether?

yes.gif Yeah, according to my example (specially posted in three angles): pronotum in profile is needed here.
Sorry, I can't help but ask the question: how often was she met in 2011, in the city of Dolgoprudny, Moscow region?

In general, I once started a topic in "Morals" about locusts in the North-West of Russia. Maybe we should move this discussion there? The situation is similar: locusta is found outside its main range, in the NW, in the center of European Russia.

All hands for it: I just specified the phase here. I have, by the way, 4 copies. they are in the collection at the moment: all from 2000 and from my region (I haven't found them since). And one of them is generally a "loner" in my opinion (if you judge by the pronotum).

The first two are caught in the pack. I found the last one and caught it for 10 minutes near the railway a little earlier... I remember finding a green one in 2010. .. And in my opinion, in 2005 there was a cluster of this species.

29.03.2012 12:23, vasiliy-feoktistov

It is suspicious that she is roaming in packs around the Moscow region (in general, since 2000. I didn't see it).
Although Dolgoprudny (there is the Moscow Canal nearby, connecting the Volga with the Moscow River and the reservoirs on it are decent) confused.gif
In terms of phases, my opinion is:
2_074.jpg and 2_073.jpg -gregarious.
2_072.jpg -single room.
I may be wrong: we'll have to wait for what people will say.
P.S. Just in case, I will attach a scan from the "Determinant of insects" by N. N. Plavilshchikov:

Good.

The first two are gregarious, and the third is solitary. The solitary one has a humped pronotum.

29.03.2012 13:50, PVOzerski

For locusts from the MO and similar regions outside the main range of the species, I suggest going here: http://molbiol.ru/forums/index.php?showtopic=267019 As for the photo , I agree with Vlad. By the way, the 3rd photo shows that the hind legs of the specimen are reddish - which is also typical for the single phase.

.jp(the latter) is most likely pholidoptera griseoaptera, from the assortment that is there... Imho, I met them myself in the park, and then caught pholidoptera griseoaptera in the same place. By the way, I didn't observe any other grasshoppers at all then, except for bush lovers.

_2.jpg (imago), _2______.jpg - male Chorthippus apricarius.
_1.jpg (the very first photo) and presumably_2.jpg (larva) - Omocestus viridulus (female and larva, respectively).

In relation to _1.jpg (photo in the middle) it is difficult to say anything reliable because of the extremely poor angle. It may be a female Chorthippus from the biguttulus group.
