Determine the type of wasp
1. August 16
, 2. September 17, Pskov region.

Come on! Even if it was shot not in our country, but in America, Africa or Australia, it will still be a female Polistes dominula.

On the birch tree should be birch

Please tell me about riders, Penza region.

July 4, Pskov region. Whose larva can it be on the grain?
The Zhukov department didn't identify her.

In continuation of Penza riders
16. A strange beast emerged from the cocoon of a grass cocoonworm. July 29th

The bee was found at the end of June, burrowing in clay soil, Novgorod region. Please tell me with any possible accuracy who it is?

And also Sphecodes, also May, Novgorod region. Same question.

Surroundings of Kirovo-Chepetsk, Kirov region. 29.05.2017.

This bee was found in July, Leningrad region. I think it's some kind of anthophora, but I'm not even sure about that. If you can identify her, please tell me.

Aren't there any other angles? Top view there..
Where in the region was the photo taken?

Good afternoon. Thank you. There is a view from above, but it's not very good. Here it is. Taken on the Crow Hill.

I give up. What an anthophora.
I have such a thing in our Flax.I didn't catch any areas.

Bulgaria, June. Polysty.
I think it's Polistes gallicus.
Please tell me if this is true.

Here's another bee. Nomada, Novgorod region, May.
I flew to the colony of Andren (Gray-haired Andren, as far as I can tell).
If the view is recognizable , please tell me.

Nomada lathburiana
is usually found in Andrena vaga colonies. They write that the parasite is also found in Andrena cineraria (do you call this species Andrena sedaya?), but I have not seen its colonies on the Karelian Isthmus, as it is increasingly solitary. Here Andrena vaga colonies are huge, hundreds of specimens

Alexey, thank you very much.
Apparently, this is the case with Andrena. Indeed, there are many large colonies everywhere where loose sand is formed. Just in case, I attach a photo - is this really Andrena vaga?

And here is another nomad that meets there in early May. Looking closely, I suspect that she is Nomada panzeri, but I would like to be more precise, if possible.

Yes, there is also the Nomada fusca described by Schwartz in 1986, which is similar to panzeri and leucophthalma. It is found in Finland, Sweden, Estonia and Flax.regions.
It is similar in color to leucophthalma. So there are possible options. Ideally, you should catch and watch. According to the photo, the other signs are not particularly visible.
