Identification of Diptera (flies, mosquitoes, etc.)

I decided to collect in one place all the equal-winged birds shot over several years. Below, the published animal is designated Bolshegolovka rusty. I looked in the Internet, in my opinion, it does not look like what was taken from me. Is it true that the Big Head is rusty, or did I mess up something when recording earlier?

... others are rare.

Last year's big head.

June 24. Surroundings of Kirovo-Chepetsk, Kirov region.

Physocephala vittata?

  
And "... other rare species" - I'm talking about sikus only, not about bigheads in general!

Family Syrphidae

Thank you!
I suspected sirfida, but.....
However, now I have found a suitable name - Pipiza quadrimaculata (Panzer, 1804)

Something even before the family fails to identify this small fly.

Help..

The most interesting thing for me is who is in the first picture, I once collected horseflies from cows, it doesn't look like, horseflies don't have such a "core" like a hefty one?

On the last one there is probably a murmur, very beautiful.
But on the average.. I'm honestly not sure, but it seemed to me that it was still a two-winged midge of some kind, about the size of approx. 2cm, or a little less, it took off so fast that I didn't even understand what was going on, and I wasn't up to it, I was afraid that I wouldn't be able to take a picture of such a beautiful one, and therefore I didn't really look at how many wings, and I couldn't tell from the picture..

alex 2611, thank you!!! Of course, I am surprised by this horsefly, it is so huge, and it flies very strangely, it seems that it flies vertically. For some reason, it occurs only until 8 o'clock in the morning, until the heat starts.

Levinkoi is also surprised, but in a different sense, I read it so long ago that I forgot absolutely everything, until recently I was surprised what kind of larvae dig in places where tarva is flooded with steppe springs, and these were larvae of lion cubs

Help..

Cyrtopogon sp. (Asilidae)?

What kind of murmur is this?

I'll assume Chrysotoxum fasciatum

Chaetorellia loricata?

something is not very - setae before the cross seam of the srsp. I don't see. Probably Chaetostomella cf. cylindrica. Although I'm still a tephritid specialist

I think it's Urophora cuspidata.

Just not quite clear Chaetostomella sp. cf.cylindrica.

Good afternoon. Please help me determine it. Nizhny Novgorod, 16.06.

I wonder if these are all sorrows.
One of them looks like a charcoal stove, but not very much. Its size is approx. 1.5 cm on the body, and the second is small, less than 1 cm, but very beautiful, But alas, this beauty is eaten, flower spider.

Hungary, June. Please tell me who it is.

I brought a larva-pupa from the land on June 23, and on June 27, such a babbler hatched. I assume Eupeodes sp. Is it possible to get to the view?
