Identification of Hymenoptera (wasps, bees, ants)

Leningrad Region, June.

3063-female Crabro peltarius (Schreber, 1784)

Thank you so much for all the pictures at once, so as not to repeat yourself.
But if this wasp is Cerceris quadrifasciata, then I probably misunderstand this beast here. He's bigger. Novgorod region, July, a large colony, flew in the heat.

I must say, the pictures are cool

Novgorod region, July. A large settlement in the trunk of an old Christmas tree. I suspect it's Crossocerus assimilis, but I'd like to know for sure.

5545, 5366-female, most likely Crossocerus assimilis (F. Smith, 1856)

Is it possible to understand at least approximately what kind of parasite is this? When I got out , I didn't keep track of it.
I found it only today, already dry, when I was getting cans of different maggots from the balcony.
It emerged from the cocoon of Euura sp., which was collected on a currant tree in the Moscow region, Sergiev Posad district, in September 2017.

And you can counter the question, how did you determine that Euura? In green, it says Euura on willows.

Thank you again.
Here is a pine forest, dry pine, early August, Novgorod region. The wasp was carrying pine aphids to the nest.

Novgorod region, July. On the old barn. I think from the pictures that it is Discoelius or Symmorphus. How do you distinguish between these two genera? (If this wasp belongs to one of them, of course)?

Novgorod region, on the old fir tree, July. I think it's Discoelius zonalis. But I really want to make sure.

July, Novgorod region, saray. This is probably the same view as in the previous set. But the color of the legs is different. And the first segment of the abdomen is different.

And you can counter the question, how did you determine that Euura? In green, it says Euura on willows.

I assumed this from the appearance of the larva and wrote Euura, not at all referring to those that live in galls, and focusing not on "green", but on the latest catalog of hymenoptera of Russia, 2017 , where the genus Euura was lumped together from other genera.
If you focus on "green", then, apparently, you should write Nematus or Pteronidea.

How to distinguish between discelius and symmorphus? Yes, it is elementary to look at the habitus. For me, on the contrary, it is amazing how they can be mixed up, and even combined in one post. Discelium is much easier to confuse with Eumenes because of the thin and long abdominal stalk. I do not know the simmorphuses, and I am not even sure that they are them, because there are several other very similar genera of small tiger-like sedge, which I did not delve into, but here in the pictures imk_6010, imi_3624, imi_3631 (and nowhere else) - definitely females of Discoelius zonalis, you can rejoice.

Why did I write, I collected galls on a willow tree in the fall and in the fall a parasite was hatched from one, which I identified as Scambus vesicarius, well, accordingly, the larva was Euura...
But it doesn't look like yours.
By the way, I just looked, and a sawfly came out of another gall, so it's a pity there's nothing to photograph. If it wasn't for your message, I wouldn't have seen it

Yevgeniyk, if it's not a secret, what do you shoot? Very good photos.

It's no secret, of course.

It emerged from the cocoon of Euura sp., which was collected on a currant tree in the Moscow region, Sergiev Posad district, in September 2017.

This is a hyperparasite from the subfamily Mesochorinae, either Mesochorus or Astiphromma, rather-the first, but the hind wing venation is not visible

And if it weren't for your message , I wouldn't have rechecked this larva, but after rechecking possible (modern) Euura on currant, I realized that I was mistaken. Apparently it was Pristiphora appendiculata.
I looked it up at Berland's, and there's a parasite listed - Spanotecnus filicornis (like it's now Perilissus?)
Does it look like mine?

It is a hyperparasite from the subfamily Mesochorinae, either Mesochorus or Astiphromma, rather the former, but the hindwing venation is not visible

Here is the rear wing (I can't stretch the other side

Here's the rear wing (I can't stretch the other side

This is Astiphromma sp. - so, it is possible to determine (there is a key-Riedel, M. 2015. Revision of the European species of the genus Astiphromma Förster, 1869 (Hymenoptera, Ichneumonidae, Mesochorinae). - Spixiana 38 (1): 85-132.)

8687 - I think Pemphredon sp.
8333 is a male Ectemnius fossorius

Can't there be a Spanotecnus filicornis?

Can not. This is Astiphromma, but who did it come from? Maybe from this Spanotecnus? Hyperparasite is the same.

4889, 4906 - I think it's Symmorphus sp., but I'm not so sure about 1382 anymore. When you can't see the key features, you need to know the group well to recognize the species. If Carcharot sees it, M. B. will tell you right away...
And Ectemnius is AVA

Yes, Dolichovespula, probably sylvestris, but the platypus is not really visible...

Thank you. You can see better here. In my opinion, it is the same wasp. The trim is yellow, with a spot in the middle. Similar to sylvestris?

Yes, Dolichovespula, probably sylvestris, but the platypus is not really visible...

And there were also such wasps. Darker and trim with an anchor-shaped spot.

4889, 4906 - I think it's Symmorphus sp., but I'm not so sure about 1382 anymore. When you can't see the key features, you need to know the group well to recognize the species. If Carcharot sees it, M. B. will tell you right away...

It is also necessary to have material from those places where they are painted quite differently. And when you can't see the dotted lines, shoulder angles, or pubescence, it's always difficult. Before the genus - пожалуйста:imi_1382.JPG
-Symmorphus
imi_3624.JPG -Discoelius
imi_3631.JPG -Discoelius
imk_5451.JPG -Symmorphus
imk_6010.JPG -Discoelius
imk_4906.JPG -Symmorphus
imk_4889.JPG -Symmorphus

Discoelius on imk_6010.JPG exactly zonalis, and the other two do not show the shape of the first segment of the abdomen from the side. Although the dotted back (which is also almost invisible) seems to be more suitable for zonalis. So let it also be zonalis.
Symmorphus on imi_1382.JPG maybe allobrogus, but in the other photos it looks like angustatus. But I'm not sure. These two common species are not found in my area, and I still have one specimen in my collection, so the material for comparison is not rich.

And there were also such wasps. Darker and trim with an anchor-shaped spot.

Probably D. saxonica. I wonder if they were "drunk" after visiting the flowers?

  
Ilya, how did you determine that on imi_3624 and imi_3631 it is zonalis, and not dufourii?

So I determined by the dotted line you mentioned - I clearly see small round pits, and not longitudinal furrows.

June, Leningrad region, on the bushes. Ectemnius lapidarius?

This is a male Ectemnius fossorius

July, Novgorod region. On the flowers of dremlik. Dolichovespula ??

Male Dolichovespula sylvestris

Novgorod region, late May, on soil.

Female Podalonia hirsuta

Thank you. You can see better here. In my opinion, it is the same wasp. The trim is yellow, with a spot in the middle. Similar to sylvestris?

Yes, it is a male Dolichovespula sylvestris

And there were also such wasps. Darker and trim with an anchor-shaped spot.

This is a male Dolichovespula saxonica

Novgorod region, July. On the old barn. I think from the pictures that it is Discoelius or Symmorphus. How do you distinguish between these two genera? (If this wasp belongs to one of them, of course)?

Discoelius:
- middle tibia with two apical spurs
-1st segment of the abdomen with a clear elongated stalk
-extended part of the 1st tergite without a longitudinal furrow, on the border with a narrow part without a transverse rib

Symmorphus:
- middle tibia with one apical spur
- the 1st segment of the abdomen is narrowed at the base, but without an elongated stalk
-an expanded part of the 1st tergite with a longitudinal furrow, on the border with the narrowed part with a transverse rib

There are other differences, but these are enough.
