Identification of Hymenoptera (wasps, bees, ants)

Yes, I realized that all this is Andrena cineraria.
Well, a nomad and even without a species....It won't help. Yes, they mostly parasitize Andren. I'd like to catch this nomad

8-female (with ovipositor) and male (without ovipositor) Gasteruption sp. It is more difficult to get to the species, you need the animals themselves.

Tell me who it is. Moscow region, June 21. It doesn't look like a hymenopteran. Only without wings. Go to the " Who is this ?" it doesn't load for some reason.
P.S. the size of a large ant. Maybe five millimeters.

You have a very poor idea of what nomad color variability is...This is generally very difficult to imagine until you yourself have at least a little time with the determinant.

I totally agree. I wanted to write the same thing myself.
You can view the" green " identifier-there is often the same type of nomad in several places. And with yellow bandages, and with yellow spots, and even without yellow color of the abdomen at all

So I'm not talking about the Nomad, but about the bee ... Or do you mean that a certain kind of Nomad parasitizes a certain kind of Andren ? so I just need to call my Andrena ...

Duc like I said it was Andrena cineraria

Odessa region, steppe, June

Please tell me who they are. Moscow region, June 12 and 20.

1-male Ammophila sp. 1 [Sphecidae]
2-female Ammophila sp. 2 [Sphecidae]
3-female Anoplius viaticus (Linnaeus, 1758) [Pompilidae]
4-5-female Priocnemis sp. [Pompilidae]
6-female Trypoxylon figulus (Linnaeus, 1758) [Crabronidae]

Thank you so much for the definitions! And when determining the membranes from photos, where, of course, you can not see the devices of the genitals, how is it easier to determine - from the pictures from the side, or from above, or so that the mandibles, jaws and cheeks are visible, or the veins on the wings? Or is it better to include a photo so that several signs can be seen at once?

Also please help identify the following hymenoformes. All photos were taken near Penza on June 14.

Alexander, can you tell me how to distinguish between Trypoxylon figulus and T. medium and why the first species is shown here?

Thank you very much! Can you tell me about this sawyer and rider? Taken the other day.

Odessa region,steppe, June.I was alone under the roof, after the rain.The size is about 14-15 mm.Calm,didn't try to fly away.

Help with the definition. Tatarstan almetyevsky district

M. O., Poplar,28.06.2015, size about 6-7mm

Epeoloides coecutiens (Apidae) seems to be. But I'm not an expert.
