Identification of Diptera (flies, mosquitoes, etc.)

Ryazan region, Kasimovsky district, Balushevo-Pochinki village, Oka River, 06.06.2012

Help identify the flies. Mordovia, June, lesnaya polyana.

1. Suppose Eristalis intracaria, male

Isn't that some kind of tahina?" I can't find a photo of this view. to make it look like mine. Everywhere with black stripes, but I can't see them

Maxim I can definitely say this is a Sirfid, the venation of the wings confirms this. With the view, I'm not sure if this color is possible .

Are there any other options? At least approximately

Fly-buzzed this. Bombyliidae, can someone tell you more precisely

Who can tell you about ktyr, sirfid and komara? The first since June, the mosquito since September 2012. North of the Rivne region, Ukraine (Polesie).

Sirfids:

d_2: male Platycheirus sp., most likely - someone from fulviventris / immarginatus / perpallidus, more precisely, you can not determine from this photo.

d_3: male Temnostoma bombylans.

I thought d_2 was Melanostoma

d_3 did not have time, you will have to find out...

d_2 Very large spots on the abdomen, our melanostomes do not have such spots. This is immediately - and so, both habitually and slightly expanded forelegs.

Hi! Recently I noticed that such green flies appeared in Moscow and outside the city:

The specimen in the photo turned out to be yellowish, but usually came across a light green color. They are absolutely harmless, especially noticeable in the evenings, fly in from the street, sit on curtains, crawl on windows. For the winter, they are hammered into the cracks of the frame and fall asleep. Help us determine what kind of insect it is. In my opinion, they weren't there before, or maybe I just didn't notice them.

Please help me determine))) A large creature the size of a large wasp, the focus missed, I can't calm down, who needs to be hunted again)))

Got my hands on it and I want to deal with this mess at last.
A big, unchildlike beast.
Collected on 27.06.202 Here: M. O. Balashikha district, okr. der. Poltevo, the edge of the forest, on pine logs.
Who could it be?

In my opinion, the spitting image of a male Laphria gibbosa!

Thank you. This another red bookman (already the second category). Rzhunimagu once again over the compilers so-as in my opinion, it is often noticed together with Laphria flava during my visits to the felling for zlatkami and barbels. It is necessary to drive him out of the CC. I apologize: this is another topic.

In our Leningrad region, too, I sometimes meet it, but in our CC (as in Karelian) it is still only in 3 categories...

Oh, and in the CC of the Tver region, Lyafria humpback is generally in the 1st category...
