Identification of Hymenoptera (wasps, bees, ants)

Well, if you held these oss in your hands, and even identified them not by pictures, but by keys and corresponding signs, then you might well not be mistaken. But there's almost nothing you can tell for sure from the suggested image.

The suggested snapshot is terrible. In the "guide" images of the best quality. And there is not such a large selection of similar species in Namibia. There the fauna is not as abundant as somewhere north-east of Essno, my definition does not claim to be 100% accurate to the species. But I'm also happy about that. that everything is clear with Rod.

Help me determine it. Mongolia.

Aha. Halictidae Most
likely Lasioglossum sp.
Male.

Can you help me with the phone call? Moscow, early May, in the forest.
I think it's something like Trichiosoma sp. of the Cimbicidae





And bumblebee still, couldn't find anything like this. MO, mid-July.

Good afternoon!
You don't need to define anyone.
Where else can you turn to such a large number of phone specialists, if not in this topic.
I want to bring to your attention my article, the content of which contradicts the generally accepted theory:
"Runners ( Cataglyphis aenescens). The birth of a new family."

I am very interested in your opinion.
Sincerely yours, VO.

I don't know what kind of species it is, but I caught exactly the same rider in the spring of 2007, under the bark
they also wintered in large numbers
, he (or rather she) also stung me
I wonder what kind of

I don't know what kind of species it is, but I caught exactly the same rider in the spring of 2007,

I identified it today as Ichneumon suspiciosus, but I would like a knowledgeable person to say it.

I defined it today as Ichneumon suspiciosus, but I would like someone knowledgeable to say it.

I would very much like to
use the" green " determinant to drive, drive, but I didn't go beyond the subfamily reliably

I really admire specialists in ichneumonids - how they define them....

where did AVA go missing??

where did AVA go missing??  

Yes, I did not disappear anywhere - work is thicker than captivity, however. And there are only 24 hours in a day...

Oh, by the way, both of the last Cerceris males are identified correctly. Success.

then maybe Medvedev should ask not to reduce time zones, but to add another five hours to the day?? It would also be useful to me, I would spend them on correspondence
thank you!!

Minusinsk, I think it's Cerceris albofasciata Rossi female.
There is a hole. The shape of the platband is interesting, elongated with a forked end. The only thing I can't understand is the description of the shape of the pygidium, is it very narrowed or not?

what will be the time, see if possible )))

Almost 100% female C. albofasciata. Both the characteristic + shape of the platypus, and the strongly narrowed pygidial field at the base, and the color of the legs are its signs.

The male, I think, is either Cerceris quinquefasciata Rossi or maybe interrupta.
There is a fossa on the first tergite, sredin.the interval field. segment longitudinally and laterally with divergent wrinkles. On the sixth stubble there are tufts of hairs, but not glued together, on the seventh stubble there are no hairs. The front edge of the trim is almost straight.

Samey, scary, covered in garbage. On wasps of Kazakhstan I go to C. rufipes, but on green and DV. like on tuberculata
A Fossa on the 1st tergite is, but poorly noticeable. The basal lobe of the hindwings is quite large. The median field of the gap. everything is smooth. The 1st segment of the middle paw is warped!!!. The abdominal pattern consists of rather wide yellow-orange bandages
, the front edge of the platypus is quite smooth, in the middle closer to the top with a slight depression (dot). The legs are completely red. The inner edge of the eyes is diverging towards the bottom.
What to believe? ))

In the male C. interrupta, the medial lobe of the platypus is densely dotted and has a broad, clear longitudinal ridge near the apex, while the hind thighs are usually red and without black spots on the apex. In addition, the overall body color is not pure black with a yellow pattern, but rather brown with white.
So, this instance obviously belongs to C. quinquefasciata.

This is obviously a male C. tuberculata. Only in this group of 5 species (2 of which can also be only color forms of C. tuberculata), the medial lobe of males has a translucent spot in the middle and an almost straight leading edge. At the same time, the remaining species of the group live mainly in the semi-deserts of Central Asia and Mongolia and are characterized by a predominance of yellow-red color of the abdomen.

As for the name “Cerceris rufipes", its history is rather complicated. And all this is due to the fact that the use of signs of color of body parts in species names is a risky business. Very many operating systems (and not only them) were called this way by different authors.

In particular, Fabricius himself described first Vespa rufipes Fabricius, 1765 (now this species belongs to the genus Rygchium), and a little later - Crabro rufipes Fabricius, 1787. Two years later, Gmelin (1789) assigned the latter species to the genus Vespa (nothing strange – then many authors considered all wasps in this genus). As a result, the name Vespa rufipes (Fabricius, 1787) turned out to be a junior secondary homonym of Vespa rufipes Fabricius, 1765 and, accordingly, had to be replaced by another name. However, no one noticed this situation for a very long time, and the specific name rufipes (in the sense of Fabricius, 1787) was mentioned in different genera – as Sphex rufipes (de Villers, 1789), as Philanthus rufipes (Fabricius, 1790) and, finally, Cerceris rufipes (Lepeletier de Saint Fargeau, 1845). Already in the same year, Dahlbom in his major work (Dahlbom, 1845) put an end to the generic affiliation of this species, but, taking into account the invalidity of the specific name Fabricius as a homonym, attributed it to the junior synonyms of the name Cerceris tuberculata (de Villers, 1789) (this species was originally described in the genus Sphex, but later transferred to the genus Cerceris (Germar, 1817).

At the same time, F. Smith described another species under the same name - Cerceris rufipes F. Smith, 1856, which was also a junior secondary homonym, but now in relation to Cerceris rufipes (Fabricius, 1787). It “lasted " a little longer, but was also assigned by Beaumont (1950) to a junior synonym of another species name, Cerceris tenuivittata Dufour, 1849, in which the medial lobe of the male platypus does not have a translucent spot with a 3-toothed leading edge. And in general, this species belongs to a completely different group of the genus Cerceris-C. albofasciata.

so we denote C. tuberculata.))) I just didn't find this species for Kazakhstan, although the keys are actually one-to-one, which once again proves that you need to check from several sources, Thank you Alexander for such a complete answer. By the way, I copy all the answers to myself, they will come in handy!! ))

It's even easier - it's the same view.
C. tuberculata is a substitute name for the invalid name C. rufipes.

As it seems to me it is Cerceris quinquefasciata Rossi female
Fossa on the first tergite is. Sredin. the interval field.segment in the wrinkles that radiate to the edges. The abdomen is roughly dotted. Spots on 2-4 tergites are almost identical. There are no 5 spots. Sternites are completely black. The front edge of the platband is raised in the middle of the recess. Yellow spots on pronotum and posteriorly yellow.

very similar to the previous specimen, but the spots on the pronotum are barely noticeable, and there are no spots on the first tergite.
surely the same view..??

well, it looks like everything in the genus Cerceris...there was one question
left as I already showed, I think it's Cerceris quinquefasciata Rossi male
I just had another similar one, identified it as ruficornis, but still I'm inclined that he is also quinquefasciata Rossi, decided that the hairs on the 6th tergite are not glued!!

I also found a male Cerceris rybyensis L !! )))
I'll post a photo somehow

Both females in the first two series of images are Cerceris quinquefasciata. The presence or absence, as well as the degree of severity of small light spots on the pronotum roller and the 1st tergite – are floating signs, since they depend on the specific conditions of individual development. First of all, try to focus on signs that are not related to color.

The male is also Cerceris quinquefasciata. In the male Cerceris ruficornis, the medial lobe of the platypus is almost flat (in the male C. quinquefasciata it is weakly but evenly convex), and its apical margin has three distinct denticles (in the male C. quinquefasciata it is almost straight, since the median denticle is weakly pronounced). In addition, the lateral fringes of their thick hairs on the sides of the platypus in the male C. ruficornis are relatively shorter and wider – their width is almost equal to the distance between them (in the male C. quinquefasciata, these fringes are relatively longer and shorter, and the distance between them is clearly greater than their width).

P.S. Yes, I wanted to add one more useful tip.
Do not immediately try to look for the apical fossa on the abdominal tergites of Cerceris. Often, because of the very rough dotted line, it is almost invisible. At the same time, Cerceris species are immediately easily divided into two groups according to the type of color of the abdomen - "correct" (light spots or bandages on all tergites are located equally-in their rear part) and "incorrect" (the 2nd tergite always has b. m. developed light spots or bandages in the front parts, and if they are not present, then there are light spots only on the 3rd tergite. In this group, the 4th tergite is often completely black, even with pronounced light spots on other tergites). Well, you should only look for a hole in addition or in cases when the abdomen is mostly yellow or red (but these are mostly desert species).

Dear Alexander, thank you again, so I am in the definitions of my types of rights and my doubts and redefinitions were also correct. As for the apical fossa, I'm at the definition (not such a large number of species, though) I already understood this and immediately focused on the location of spots on the tergites. And about the hole rather write already automatic.

Here it seems to me it is Cerceris rybyensis L. Male.
The location of spots on the abdomen is irregular.
The frontal keel does not reach the first eye.
The lower legs are yellow, without black, But the punctuation is quite clear and rough!!
Flagellum of antennae with very short hairs.
The distance between the eyes is less than the distance from the eye to the eye.
Sredin. the field is wrinkled.
On the 4th and 5th tergite there are thin light bandages, on the fifth slightly thicker than on the 4th
Bandages of glued hairs on the leading edge of the platypus are equal to the distance between them.
Zadneschitik black, the front edge of the plate is also black

is this Crossocerus dimidiatus F ?

Yes, it is a male Cerceris rybyensis

First, you should have been immediately alerted by the flattened segments of the flagella of the antennae. These are not found among our Crossocerus.

Secondly, if you look closely, even in the picture you can see that the parietal eyes are NOT located in an equilateral triangle, which is one of the main differences of the genus Crossocerus.

In short, this is a male from the genus Crabro. Here with the view is more difficult, since the main signs are not visible, first of all, the front legs (they usually have flat scutes characteristic of each species).

I agree with AVA. A similar wasp was caught by me in the Center. Kazakhstan. After definition, it came to the genus Crabro.
