Identification of Orthoptera (grasshoppers, crickets, etc.)

Here is a question. Can a grasshopper be identified by its voice? I've heard it seems to be well defined.
Geographically-Kiev, September month.
the forum program does not allow you to attach audio, so I had to archive it.

Ephippiger ephippiger. In terms of time and place, we have it. I will assume either on the Bald Mountain or in the area of Vyshgorod was found. I've never heard of it in an urban environment. Perhaps someone can clarify the phenology of the species or its love to climb trees in coniferous thickets without exception, while at other times it is constantly located on bushes and occurs as in the steppes (Kamyanets-Podilsky (Dniester), I heard it north of Odessa) and in the forest (Kiev, Dymer, Irsha)?.

I know that the wrong topic, the other is not found.

Dracus, thank you! I thought it was some kind of locust, but it turned out so great.
Can anyone tell you about the grey fillies?
I think that the whole company can be attributed to Chorthippus biguttulus. But I would like a competent opinion.
this I define Chorthippus dorsatus as a male, but I'm afraid to make a mistake.

Please help me identify the grasshopper. July 2017, Belarus, surroundings of Grodno, meadow near the river. The photo is not very high-quality, but you can't do anything else.

Good afternoon.
Can you tell me if Notostaurus has red wings?
I can't attach the photo for some reason

Good afternoon!
Here is the link to the photo

Did you notice that the living one had the same color?

Help identify locusts.Is this Oedalius Decorus?
Caught on Yegorinom place, on the slope of a long mountain, and the slope down stretches to the railway.They came across in normal quantities.
And what is the size of the largest individuals of these locusts?

Yes, Oedaleus decorus. It is strange that you ask - you have it, in theory, to one place should be, in person it is time to know)))
Females are slightly larger than Oedipoda caerulescens.

When I was in the camp "Eaglet" in 2016,I met 2 females of brown color, 4.2 cm long, I remember by the tooth.I also have females,only the green one fell apart, and the other 3 are whole.
The date of capture of 3 males of Oedalius Decorus is the beginning of July.
And they met not only on the Yegorin place, but also on the Nikitin pit and the Sarkelovsky coast.I wrote about these places in the topic "Positive temperature anomaly".
Now Epacromiini, on the right Aiolopus Thalassinus?I was caught near the coast of the river at the camp site "Tikhaya Gavan", on juicy short grass.Nearby was the Don River.The rest of Epacromius, only up to the species could not determine.

Epacromius Tergestinus are caught on Yegorinom place except for the one that is on a needle with the left pair of wings spread out.The one on the needle was caught in Vladik's field, 200 m north of my house.Vladik(my friend) and I went out to his field and found her.
And again, the photos are not loaded,I wanted to show Prusov on the screen .

Hello! Can anyone provide information on the differences between Bryodemella tuberculata subsp. diluta and the nominative species Bryodemella tuberculata tuberculata? I can't find anything... In the Southern Urals, even if you do not distinguish between these taxa, the broad-winged bird is rare - in the summer of 17, 2 specimens were recorded in total in the steppe regions, of course, they were not specifically searched for, but... The only photos more or less reliable, these two taxa, found on http://orthoptera.speciesfile.org

Epacromius tergestinus is slightly larger than the specimens you showed. At a glance, you have 3 species: Epacromius pulverulentus, Ailopus thalassinus, Platypygius crassus (at least in the left row, the second one from the bottom is very similar). But from photos from this angle, it's impossible to tell for sure. Epacromius is well distinguished from this group by the narrow gap between the mid-thorax lobes, and the lobes themselves have a rectangular edge.

Please tell me about these fillies. Penza region.

1-Chorthippus sp.,
2,3,6-Chorthippus parallelus,
5-Stethophyma grossum.

All Conocephalis discolor.In females, the ovipositor can be of different lengths and shapes.Ovipositor forms:xiphoid, sabre-shaped.Ovipositor length:9-16 mm.
