Parodontodynerus ephippium (Klug, 1817)?
Polistes nimpha unusual colors?
Philanthus coronatus Fabricius, 1790 subspecies?  

Maybe someone knows what it's called:

These and other eumenins from your collections are very small and nothing can be seen from the signs (the structure of the zadneschitika, propodeum, the second segment of the abdomen from below and above, tegula), in the absence of a complete collection of the fauna of the region, there are no chances, but if you can turn the specimen in front of you, 90 percent, I think, is quite definable.

Where is Parodontodynerus ephippium? If on DSCF4730.JPG — (110.9 k), then it's not him, rather Euodynerus.

Please identify, if possible, this copy on 04.11.12, Rostov region.

Why did you decide that? Because of the lack of a "basket"? So it's just a male Bombus.
By the way, "cuckoos" are just a subgenus of the same genus.

Not necessarily - P. nimpa periodically captures other people's nests.

4732-see if there are yellow spots on the mandibles. You can't see it in the photo, but if there is, it's P.biglumis , if not-P. nimpha

4735-it is more difficult with males, because it is necessary to compare the length of pubescence on the mid-spine (in P. biglumis, the hairs are longer than the thickness of the costal vein, in P. nimpha-shorter). In addition, in the male P. biglumis, the sides of the platypus are almost parallel, and in the male P. nimpha, they converge downwards.

I know that Rod is alone. The wings are still dark brown, and the overall coloring is more like one of the cuckoos.

The specimen you named as P. biglumis is a selected individual of the smallest size from the wasp series of this species. I think so: either P.biglumis or P. nimpha. I have several P. nimpha from the Kharkiv region-they don't look like these.

I do not yet know about the findings of P. biglumis from the territory of Ukraine. This species is found slightly to the east.

Good evening! I shot this heavyweight bumblebee in the vicinity of Chisinau, on April 3, 2009. He was pollinating an almond orchard. Please tell me its Latin name. I will be very happy. Thank you. :-)

Probably Bombus terrestris or Bombus lucorum.

Hello! What is the Latin name of this black bumblebee (in appearance, it seemed to me very alarming because of its size and danger, but it did not touch me and always bypassed). Chisinau neighborhood, May 18, 2009. Thanks!

This is not a bumblebee, this is a single carpenter bee-Xylocopa sp., not aggressive, if you do not grab it with your hands and do not push it into your mouth, then they are not dangerous

Xylocopa valga! Ocd. Chisinau, April 4, 2009.

Why not violacea for example?

I understand that this is not a Carpenter Bumblebee, but a carpenter bee.

As far as I remember, there are no carpenter bumblebees. All species of the genus Xylocopa are called carpenter bees in Russian. The main species-valga, violacea and iris-differ in size and in a variety of features that are visible only on the specimen.

no

I wonder who it is, then?

look at the wiki on the topic of territory and you will see that it does not look like it at all, but in general, the wiki is built on the principle of " OBS " = "one grandmother said", and not one self-respecting person will go there to look for information. Your bumblebee is more like a field bumblebee, but I repeat, I'm not an expert in them
