Identification of Hymenoptera (wasps, bees, ants)

In the Crimea (Feodosia) I met a very severe wasp, I had never seen such before. Unfortunately, she escaped capture, and there is no photo. There is a description (below): maybe someone will have an idea what it could be, because I made an impression!
Size-visually 4-5 cm, but even more massive than scolia maculata. The structure is similar to a very broad, stocky sphex. The color is dark, even, brown-bronze, with a gloss. The wings are the same. It flew very hard and loudly - as a result, it was initially mistaken for a large beetle. While I was trying to unpack the net, it landed, looked for something in a crack in the ground, and flew away into the distance

Hello, please help me. There were wasps in Dnepropetrovsk, 5-6 centimeters in size, two or three individuals live in burrows. I am far from insects, I am very afraid of them, they are in our yard, in the country and in the garden, in short, everywhere, I have never seen such things before. I want to learn more about them.

On the idea of scoliosis... Like this?

Help me identify a wasp from Slovenia. July, Julian Alps 1200m

This is not a hymenopteran, but a dipteran. Mukha-ktyr.
By the way, they say that it bites quite painfully.

I apologize for repeating myself. I already asked in the general topic, but I didn't get an answer. Maybe you should have chosen a more specialized one right away.

Please help me identify it. Filmed in the Kherson region.


P.S. I'm not sure what I put in the right topic this time either

Hello, colleagues.

This summer at the dacha (100 km from Moscow) in a wooden house got strange creatures. Very similar to wasps, but without wings. About 2 cm in size, the head and chest are black, the belly is black-brown striped. It bites painfully, but it doesn't leave a sting (it hasn't yet, at least). Very tenacious. When in danger, it emits a fairly loud squeak. Who is it and where to look for a colony-spraying insecticides in corners and crevices does not bring much benefit, and the number of these insects is growing every day.

  
As for the wasps, a black wasp regularly comes to me and tries to make a house in a hole on the windowsill of the balcony. I catch her regularly and send her out

This is not a fly, but a rider of the genus Evania. Parasitizes cockroach ooteks.

I didn't have time    
I have a few of these animals in my collection.

But this Ammophila can be defined as a species?Filmed in Moscow.
