Identification of Hymenoptera (wasps, bees, ants)

Help us identify the client. Khar. obl. Bliz-kiy district 12.05.2011. Thanks!

I would say it is Bombus argillaceus (Scopoli, 1763)
In the Donetsk region, quite a common view.

Good afternoon! I don't know who it is. Please tell me. Taken in Chelyabinsk on May 14, 2011.

under No. 2 Bombus pascuorum

And why shouldn't it be Lestica, for example, alata Pz. - ?
Sort of like a trans-palaearct. Take a look. And the head, like the rough punctuation of tergites for Ectemnius, is IMHO atypical

Well, why for example? This is the male Lestica alata (Panzer, 1797). Just look at the shape of the 1st segment of the front legs and head in front. A good difference between childbirth is the severity of the parietal grooves near the inner orbits of the eyes, but here they are not visible.
As for the dotted line, it is not so simple here - among Ectemnius there are quite strongly dotted species, and among Lestica - weakly.
Finally, in Ectemnius schlettereri (Kohl, 1888) (as in most species of the subgenus Hypocrabro), the lateral spots on the 3rd abdominal tergite are either much smaller or completely absent, the 1st segment of the forelegs is not flattened, and only the 1st abdominal tergite is roughly dotted.

Male Crossocerus. About 8 mm.

It is similar to Crossocerus elongatulus (Vander Linden, 1829), but some important features are not visible.

I'll check for this view. and what signs are needed?

maybe it's a female just Lestica alata Pz ? The punctuation of tergites is rough, and there are stripes on the inside. parts of the eyes

As it seems to me, this is Ectemnius schlettereri Kohl male.
1st abdominal tergite in rather rough punctuation.
The 3rd part of the mustache is more than 3 times longer than its width. With a clipping only the 6th part of the mustache. The rest are straight.
The 3rd tergite is completely black, with the largest spots on the 2nd tergite.
Smooth field of the forehead without a transverse limiting keel
of the crown, mid-spine and 1st tergite in rather long raised hairs.

Help identify the bee (Andrena sp.?)
The body was found in a bus in the east of Moscow on the night of May 8-9

Please help me determine
the pictures are weird, but that's all that came out until the camera is not zdoh
23.04.2011 I dug a nest under the bark of a birch tree, some megachiles with a total score of 18 cells, yesterday 10 pieces were bred all males
are green on the upswing Megachile will(o) ughbiella (Kirby, 1802)
we are waiting for the remaining eight maybe there will be females
the last segment the antennae are extended, although the photo does not show
the 11th one, where the females are
[attachmentid()=111503]
[attachmentid()=111504]

Yes, the female Lestica alata (Panzer, 1797).

As it seems to me, this is Ectemnius schlettereri Kohl male.
1st abdominal tergite in rather rough punctuation.
The 3rd part of the mustache is more than 3 times longer than its width. With a clipping only the 6th part of the mustache. The rest are straight.
The 3rd tergite is completely black, with the largest spots on the 2nd tergite.
Smooth field of the forehead without a transverse limiting keel
of the crown, mid-spine and 1st tergite in rather long raised hairs.

Yes, male Ectemnius schlettereri (Kohl, 1888)

I think this is Ectemnius fossorius L. the male
is quite a large specimen. 12-13
mm. long whiskers are not flattened, but with teeth (4,6 ch.). Front thighs without teeth.
Front swivels with a prong. The first part of the hind legs is curved.
Mid-spine shield with transverse wrinkles. Pronotum collar with sharp corners. Crown with transverse wrinkles.

about Crossocerus, what signs are needed?

I think this is Ectemnius fossorius L. the male
is quite a large specimen. 12-13
mm. long whiskers are not flattened, but with teeth (4,6 ch.). Front thighs without teeth.
Front swivels with a prong. The first part of the hind legs is curved.
Mid-spine shield with transverse wrinkles. Pronotum collar with sharp corners. Crown with transverse wrinkles.

Yes, a male Ectemnius fossorius, but only in the first 4 frames. The last two have something completely different.

about Crossocerus, what signs are needed?

Well, if it's a male Crossocerus elongatulus. then it has:
- abdominal tergites without yellow spots
- 2nd tergite at the base without clear transverse constriction
-platypus without yellow spots
- the forehead on top and crown in relatively short hairs are not longer than the diameter of the eye
- the pronotum roller on the sides is bluntly angular
- the bottom of the chest is covered with short hairs that do not lengthen in the front part
- the sides of the mesopleurae in front of the middle basins are rounded, without a sharp denticle
- anterior trochanter without an angular protrusion below, not thickened and sparsely, short hairs
- anterior thighs below convex and without an angular protrusion at the base, without long hairs
- anterior tibia not expanded, below in short hairs
-middle thighs at the base below without a tooth, expanded and without hairs
- the middle lower legs are slightly indented from the middle to the top
- hind legs not very thickened towards the apex
- the last (7th) tergite of the abdomen is black, not roughly dotted, slightly rounded or almost straight cut

In fact, such signs need to be evaluated directly. It is quite difficult to do this from photos. I highlighted the most important ones in color.
Try to carefully go through the theses of at least the "Green" determinant. In principle, they work quite well.

the last tergite is shaped like this, with the rest of the signs seem to fit.
in addition, questions about the size, the nearest views are not more than 6 mm.

Funny. When I have time, I'll look at the materials to see how much this attribute is variable.

I think this is Ectemnius fossorius L. the male
is quite a large specimen. 12-13
mm. long whiskers are not flattened, but with teeth (4,6 ch.). Front thighs without teeth.
Front swivels with a prong. The first part of the hind legs is curved.
Mid-spine shield with transverse wrinkles. Pronotum collar with sharp corners. Crown with transverse wrinkles.

And here are these shots:

1010218.jpg
1010219.jpg

this is a different view (which, not quite clear, is not enough data):

I think it's a male Crossocerus vagabundus. 8 mm.
Forehead, mid-spine shield, scutellum, 1, 5 tergites are black, but on 6 an unpaired transverse yellow spot at the base.
The length of the 1st tergite is almost equal to its width. Front thighs with a small clove on the outside.
The top of the forehead is noticeably dotted, but not very rough. The platband is without teeth, only at the top it is extended into a small prong. The last part of the us is conic.

And here are these shots:

1010219.jpg

what other data is needed? Just quite easily (for myself) came out on this particular view.
here's another one of his faces

7-8 mm. I think it's a male Crossocerus quadrimaculatus. Although the platypus and mandibles are black. The scapus on the side is yellow. The top of the platband with two paired teeth, in the middle a clear notch, behind these teeth a little further on another pair of teeth, then poorly visible, hidden behind the hairs.
What are the parietal areas, this is on the side of the side eyes? There are clearly bounded rounded shiny bumps. The top of the forehead is clearly and rather densely dotted. The occipital suture was never fully understood. It is written that ends with clear denticles. Do they need to be looked after by the front basins? The last segment of the mustache is cut off.
On 2-3 tergites there are very small yellow spots with blurred edges.

And here are these shots:

I take it we are talking about the images that I deleted??, it was from Lestica alata

Dear sirs!
Help me find out the name of the insect!
These flyers wintered in a large colony in a country house (a fresh pine log house in the north of the Leningrad region). They started to wake up at the end of February. The size is approximately 4.5 cm for large ones. There are smaller ones - see 2-2. 5.
You can't take a high-quality photo - the models don't want to pose and fly away noisily.

You can only sympathize and hope that this will not happen again.
This is a male of the blue pine horntail Sirex juvencus (Linnaeus, 1758) (males are smaller, females are larger).
Typical and unpleasant pest of construction wood, whose larvae last for 1-3 (rarely more) days. they develop in the wood of medium-aged pine trees (sometimes fir or larch).
Remove insects, process the log house.

Once again I drove away the already starved male today (post 2199) on the "green" came out the same Megachile will(o) ughbiella (Kirby, 1802). How is it spelled correctly with or without an" O"?
While I was at work, 3 more bees came out, 2 males and finally 1 female, there are still 4 cells left, I hope all will be females.

This is the kind of thing trapped between the window panes. Surprised by the size: about 4-4. 5 cm. It was interesting to learn from experts what this huge monster is.

Location: Belarus.

Photo through the window pane, the subject was moving, so don't be angry.

probably common hornet Vespa crabro L.

AVA!
Thank you so much....
Yeah. The log house is new, apparently the logs were already with larvae when cutting.
I'm now looking for something to process..

Help us identify a bumblebee from South Karelia. Found today, on a dandelion tree.

Nothing strange about the size, this is the overwintered female founder hornet Vespa crabro Linnaeus, 1758. The workers are relatively smaller, but they will fly in two weeks.

Don't write the specific name without O.

This species was originally described in the genus Apis in the monograph:

W. Kirby. 1802. Monographia Apum Angliae; or, an attempt to divide into their natural genera and families, such species of the Linnean genus Apis as have been discovered in England; with descriptions and observations. To which are prefixed some introductory remarks upon the class Hymenoptera, and a synoptical table of the nomenclature of the external parts of these insects. Volume II / J. Raw, Ipswich. 388 pp, pl. 15-18.

Description of the species on page 233:
41. A. Willughbiella

Происхождение названия на стp.235:
I am led to give A. Willughbiella as the Willow Bee, whose history and economy so attracted the attention of the English Naturalists of the last century, by the circumstance of its having been most commonly taken in places abounding with willow trees.

If you would like to see the description, please provide a link to the monograph:
http://www.archive.org/details/monographiaapuma02kirb

In any case, the correct name is Megachile willughbiella(W. Kirby, 1802)

Alexander, can you tell me anything about my latest wasps?
thank you

I think it's a male Crossocerus vagabundus. 8 mm.
Forehead, mid-spine shield, scutellum, 1, 5 tergites are black, but on 6 an unpaired transverse yellow spot at the base.
The length of the 1st tergite is almost equal to its width. Front thighs with a small clove on the outside.
The top of the forehead is noticeably dotted, but not very rough. The platband is without teeth, only at the top it is extended into a small prong. The last part of the us is conic.

All correct-male Crossocerus vagabundus (Panzer, 1798)

about Crossocerus quadrimaculatus?

It seems to me that this is Gorytes bilunulatus female. The first tergite with deep constriction. Median field of the gap. the face is wrinkled, the wrinkles disappear at the base, where the surface is smooth. On the first tergite, there is a fairly clear transverse indentation at the base. The second tergite with an interrupted yellow stripe. 1-2 tergites are quite clearly dotted.
