Identification of Orthoptera (grasshoppers, crickets, etc.)

Help plz determine.
Moscow region

  Tettigonia viridissima?
Moscow Region, Istra district

Tell me what kind of animal it might be. Whiskers short, probably locust, color dark brown, length about 1 cm. Without a photo, of course, it is difficult to determine, but this "grasshopper" has a characteristic habit - it can swim under water... The first time I noticed him in the water, I thought that he just accidentally fell, fished him out and let him go. And then once again I saw the same one sitting under water on a plant, I scared him off, he swam under water...

But tell me if it's locusts or not. Big cm 4-5. Oh! I spied on you. Is it Tettigonia cantans? This one is found in the Zaporozhye region.

Question about Tettigonia viridissima, now that we're talking... How often does it occur in the Ministry of Defense? I've only seen it 2 times, although Tettigonia tsantans is very common...

And what is this erect wing?
Poecilimon sp.?
Surroundings of Nizhny Novgorod, 02/07/2007

Look at these straight-winged ones, maybe you'll recognize someone. Luhansk region. Of Ukraine

What is this filly from MO?

What is this filly from MO?

Larva of Stethophyma grossum - marsh filly. The white-banded filly Ch. albomarginatus is not like that

Please tell me the name of the genus and perhaps the name of the most common species of this insect in the middle zone.
There is no photo, but I will try to describe it.
The body length is up to 5 mm, bouncy, in general, somewhat similar to a grasshopper, but the grasshopper has a head and chest separately, and these (at least it seems so to the naked eye) have a head and chest merged, something like a cephalothorax in general. Orcas can be green or brownish... They live in the same place as grasshoppers, they are often found in many places...

In Samara, too, one such photographed, och melkii they are hard... Can you tell up to the view from the photo?
And look at my pryamoptera, with the names confused.
1w and 2w nymphs of fillies (but which ones??? ); 3w, 6w and 7w also seem to be grasshopper nymphs; 8w the grasshopper itself (you can at least determine the genus), but 4w is an adult filly. Help me I can't figure it out without you

Here is a higher resolution, etc. photo with a similar view (in my opinion?)

This is a nymph, not an imago? (the wings are not developed)??

Is there a male on the left and a female on the right in photo 9w?

Here today naschelkal straight-winged, with the definition of help:

This one, near Moscow, Ch. dorsatus or some Ch. albomarginatus?

Hello. It is very necessary to determine what kind of grasshopper is in the photo, this is for the newspaper. Please help me! It's a pity, of course, that the photo is not as high-quality as the others, but how did it happen? It was photographed in May of this year near the Big Almaty Lake in the foothills of the Trans-Ili Alatau.
Thank you in advance for your help.
