Identification of Hymenoptera (wasps, bees, ants)

then, imho, this is Brachystegus scalaris (= Nysson scalaris), just as the bembex colony was nearby

Yes, it is quite possible to check the forehead again.

Please advise the keys to the xylocop definition or help with the definition (unfortunately, I can't make a better photo yet...)
I can assume that this is Xylocopa valga, but how to distinguish it from X. violacea and X. iris, indicated for the territory of Ukraine.
The insect was found in the town of Berezno, Bereznovsky district, Rivne region (Ukraine)

001-Vespa orientalis Linnaeus, 1771 (Vespidae, Vespinae) - eastern hornet. It is not found in the MO, and in general in Russia there is only in the south itself
002-Cimbex femoratus (Linnaeus, 1758) (Cimbicidae, Cimbicinae) - birch mace sawfly
003 - Vespa crabro Linnaeus, 1758 (Vespidae, Vespinae) - common or European hornet
004 - Ammophila sabulosa (Linnaeus, 1758) (Sphecidae, Ammophilinae) - Ammophila sand
005-Sceliphron destillatorium (Illiger, 1807) (Sphecidae, Sceliphrinae) - Sceliphron vulgaris (sometimes called Pelopean in the old-fashioned way)

This is some obvious mistake, if not a " provocation”.
Of all the species shown, only hornets (001, 003) can be “interested” in honey. The rest of us don't need it at all. Well, the birch sawfly is a predator at all…

PS
By the way, it would be interesting to know what method the author used to clean the specimens from honey, even if the micro-pollination was not affected...

If you'll excuse me, I'm not a pro at "cleaning up", I had to tear off the most involved legs and sawyers....... But I can assume that Cimbex femoratus flew just to eat Sceliphron destillatorium (they were alive when I pulled them out). And Ammophila is really superfluous. I didn't even know what she'd left behind. But they fly into my attic more often than other oss.

Help me determine it. It looks like a bumblebee, but it flies like a fly. Shot in August in the Tien Shan Mountains at an altitude of about 1500 m. above sea level.

I will assume that in the photo Xylocopa violacea or Xylocopa valga, I give a photo of the differences between these species taken from the Internet

Krasnoyarsk. Stepanovka village on a pine tree. There were only males before, similar to Eumenes coarctatus L female. The hairs on the crown and sides of the chest are thick, long, raised. The 2nd sternite is almost bare, there are no long hairs. 2nd tergite in raised hairs only at the base. The marginal border of this tergite is black. Us. Completely black. On the platypus, the hairs are long at its top. The frontal spot is rounded, does not reach the platypus. Yellow stripes on 1-4 tergites, on 3-4 in the form of central expanded spots.

similar to Eumenes coarctatus L female.

Very similar. If there are no long shaggy hairs on the middle and rear basins , then it is (Determinant of the Far East, fig. 146-7 on page 319) .

Yeah, no :-))
thank you!! Mostly watched on green.

Thank you-Xylocopa valga was released. I also found differences in the sculpture of the shin covers: in X. valga, the outer side of the hind tibia is completely covered with small teeth, and in X. violacea, there is a "receding hairline".

The information is taken from the Red Data Book of Ukraine.

And what are the differences between X. valga and X. violacea and X. iris (as I understand it, only these three species are found in Ukraine)?

X.iris - 1 cm smaller than X. valga and X. violacea.
Also X. iris is much less common in nature.

Yes, only these 3 types are found on the ter. Ukraine, but this is not the most fun things from the hymenoptera that are found here.

To the article - in the photo-both females.
The males look different, especially the bizarre ones in X. iris!!!

About 12 mm. I think it's Symmorphus murarius L, although I don't see any dimples on the crown of the head. Shoulder angles of pronotum smoothed, not pronounced. The top of the chest is covered with long, rather dark hairs. The 1st tergite on top is quite wide, densely and roughly dotted. The transverse roller on the 1st tergite is not pronounced, the inflection is smoothed. The lower legs are yellow. Intermediate segment with ironed sides, slightly matted wrinkles on the sides. Maybe it's not Symmorphus at all ??

I think it's Odynerus spinipes.

I think it's Odynerus spinipes.

so I felt that I went to the wrong steppe, let's redirect our search

Can you tell me if I identified it correctly?

14.07.2011
MO, Railway
Length about 20 mm

male Anthidium florentinum?
[attachmentid()=135148]

Good time of day. Please help me identify this bumblebee. Just like in Hymenoptera.

Thank you in advance.

Please, Bombus sp.

And it seems to me that this is still some kind of cuckoo (Psithyrus). Something dark wings in my opinion for a "clean" Bombus?

And it seems to me that this is still some kind of cuckoo (Psithyrus). Something dark wings in my opinion for a "clean" Bombus?

For our south, wings are not an indicator at all. I have, for example, the steppe Bombus agrilaceus. The wings are very dark, just like our northern cuckoos.

Well, besides, Psithyrus is now included in the genus Bombus as a subgenus.

Thanks for the clarification. I really didn't know about the southern ones.
And I know that Psithyrus is now a subgenus of Bombus. Therefore, for clarity, I wrote: "clean" Bombus.

Please, Bombus sp.

Thank you very much. Can't you be more specific? Or what body parts should be shown for identification?

in profile, take a picture of the hind legs on the outside, while cuckoos have lower legs without shiny hairs.

I think it's Odynerus spinipes.

I agree, according to the signs, a female of this species comes out, I was confused at first by the shape and size of the wing caps, I thought one was too large and the other was shaped, I have a male of this species, in which they are rounded and small.

Krasnoyarsk. I got caught on a Siberian larch tree. Male. Top of the platypus with weak, poorly visible 3 prongs. The front edge of the platband is black. Parts of the face in large rare spots. The flagellum of the mustache is red from the inside. The last part of the mustache is slightly bent. Srednespinka from above in rare deep, slightly longitudinal points, slabobelstyaschaya, slaboshagrenirovannaya. Sides of the mid-spine in a dense cellular wrinkled sculpture. The gap. the segment is coarsely cellular and wrinkled. 1-2 tergites in rather dense and rough spots, the rest in a more sparse and shallow dotted line. Solid bandages on 2-5 tergites. Pygidial field in rough points, weakly shining, shagreen. 7th sternite in rather long and dense hairs directed back, 6th sternite from the sides there are no bunches of glued hairs. As a variant of Cerceris flavilabris F, but something doubts take.

Thank you very much. Can't you be more specific? Or what body parts should be shown for identification?

You can try, but still 100% guarantee no
Head, chest, belly in profile, so that you can clearly see the color and nature of the pubescence, from above the color does not show through
The Hind legs
Now I do not remember, but there is nowhere to look at work
There in my opinion, the ratio of the size of the parts of the head, the location of the eyes and the ratio of the size of the segments of the antennae with each other and parts of the head, I think this is not real from the photo, but I think it will be possible to reduce it to a couple of three types
, and so 50% for Bombus bohemicus, 10% Bombus vestalis, 10% Bombus sylvestris, and the remaining 30% for anything from the Bombus terrestris color group, I think There are a dozen and a half species in ukraine

I think the male is Anthidium florentinum.
A. manicatum has teeth only on the last two segments, the color is more black, the size is smaller.

100% not manicatum
in a pancake blunted, I thought in a post florentinum wrote
Can there be or not something else similar to florentinum?
I have on Anthidium only "green" and the material is not thick, and recently quite a lot of animals in the MO appeared, which as it were should not be

Still most likely Anthidium florentinum

in profile, take a picture of the hind legs on the outside, while cuckoos have lower legs without shiny hairs.

I took some photos. Take a look, if something is missing or the quality is not satisfied, tell me - I'll take a photo again. Here's what happened.













Thanks!

Psithyrus type vestalis seems to me, but I do not determine the photo.. as experience shows: -)))

In my opinion, Bombus (Psithyrus) bohemicus Seidl 1838

perhaps ))), you will need to look at your

Thank you so much for your help! Here's another question. Yesterday I found either a clutch or a pupa on a spruce conifer. So, the Moscow region (Kratovo), the end of February. The length is about 2 mm. Who is it?

So it hatched. Who is it? The length of the insect is about 2.5 mm.

So it hatched. Who is it? The length of the insect is about 2.5 mm.

You have hatched a parasitic membrane Pteromalus puparum if I'm not mistaken, parasitizes on the pupae of butterflies
