Identification of Hymenoptera (wasps, bees, ants)

THANK YOU, Alexander, I have previously exhibited oxybelusov, there will be time to take a look. Thanks

I'm sorry, I don't have much time...

With the 1st and 3rd, it seems to be hit. But with the 2nd it is more difficult - you can not see the abdomen from below. But, most likely, this one is also like the 1st one.

By the way, my advice is not to stick insects so that then the signs are not visible. If you really need to glue, then for the side - there are still two of them.

Alexander thank you for your help! I fully understand you about the time, I have received comments from Pavel Nemkov on them, and I will continue to work and understand them. About boca I agree

I'll introduce myself. Alexey Molchanov. Age - 50 years. On expeditions - the whole USSR PLUS...)))
Herman Nikolaevich-was my research supervisor. In the 1980s, more than 15 articles on Apoidae were published. Personal collection transferred to Omsk University.
Please accept my text-without too much emotion. If I was too emotional, please excuse me!
Your position has the right to exist, but I can't agree with it, I'm sorry!

Hmm... New faces in this thread. They would have introduced themselves... And then it is not clear how far you are from halikodoma and from Minusinsk too
As for the nests. Then Sasha Vateryga's opinion should be trusted, since it is difficult to find more competent megachilid nesting sites in the former Soviet Union than him and Ivanov.
By halikodome. Megachile (Chalicodoma) desertorum Morawitz, 1875 occurs in southern Buryatia and Tuva. Most likely, this species is also found in Minusinsk. By the way, Minusinsk is a very interesting place, from where many perepons, including bees, have been described. And there are enough rarities there. For example, in the summer of 2012, Comrade akulich-sibiria caught Epeoloides coecutiens (Fabricius, 1775), one of the rarest bees in the Palearctic.

Thanks a lot for the information, but halicodomes are still more thermophilic! In Tuva and Mongolia - I will not argue, this genus is represented, but to the north..... And epilloides is not as rare as they say! According to my observations, although conducted in 70-80 years, the years of these bees are extremely short. But at the peak, on the host colony, I observed up to 7-8 individuals in the Moscow region-more precisely in Chashnikovo.

Good afternoon! Could someone identify this ngasekomoe? Taken in Bolivia at an altitude of about 4000 m.
There are not many flying insects there, so I would really like to understand who it is.

clearly a fly from the ktyrei family (Asilidae)

For example, in the summer of 2012, Comrade akulich-sibiria caught Epeoloides coecutiens (Fabricius, 1775), one of the rarest bees in the Palearctic.

Really rare? I caught 8 fish in the Leningrad region, 6 of them near the house, on the territory of St. Petersburg. True, we have a lot of Macropis here, so it's probably not surprising.

Thank you very much!

Really rare? I caught 8 fish in the Leningrad region, 6 of them near the house, on the territory of St. Petersburg. True, we have a lot of Macropis here, so it's probably not surprising.

The legend about the rarity of this species came from the" green " determinant and from Mrs. Ponomareva, a student of V. V. Popov.. I won't say anything, but some estimates are based on incomplete research and rather limited information. Unfortunately (or fortunately for the host), not all macropis colonies are infected. I specially picked up my diaries, in Chashnikovo in 1978 I counted 7 colonies of macropis, but only one was infected!!!!!!! Unfortunately, I did not continue the research of this tandem, but I did note that epioloides years go from 7 to 10 days in total. This ID is characterized by a well-known "laziness" - tracked flights are no more than 40-60 meters. It is not a fact that there will be another host colony in this diameter. In the Ulyanovsk region 1998 observed colonies-makropisov three / four-the third colony was divided into two parts and epioloides there saw up to 5, although not marked, they flew through all the colonies! And the colony is 500 meters away - I didn't see a single one!

  Yes.... After these words, my teachers-Gornotaev G. N., Klimashevsky S. M. And others, I will not pour out surnames.... Just a hand would not be given to you! Or just smiled politely! But most likely both....

I don't know S. M. Klimashevsky, but I was very close to G. N. Gornostaev. I don't think you're right about the hand and the smiles. It is more likely that he would have understood my position.

Why do WORLD-renowned scientists freely share information with"amateurs"? Can I give you a list?

Well, yes, they are divided, but in very limited quantities. And not the one they're currently working on. And here's a list, please. It would be interesting to get acquainted…

And research is not creativity, it is painstaking, painful, and often invaluable work! If you want - the work of a prospector at the mine! A "creative" - the creators of concepts and view writers "creative" easily go into obscurity in life! Should I give you a list???

It is not necessary to explain what scientific research is to a person with more than 30 years of experience in just such work. Otherwise, I didn't understand much of your maxims. Although it would also be interesting to get acquainted with the list of obscure "view writers" [sic].

...Your right to share information or not. It is your right to correct or not your fellow collectors! But no one has the right to wear a crown and be proud of it!

Yes, this is my right, and I will use it for the time being. But please give me an excerpt from my posts where I "put on" [sic] the crown and am proud of it.

But I suspect that your righteous anger is simply due to a lack of understanding of the issue, since you yourself are obviously very far from the scientific field in which I move.

A few comments! And I believe that the discussion on the" dressing " of the crown should be over.
Indeed, I began to return to entomology, already as an amateur collector. Many things have been forgotten or I don't have any information, and I may have returned to collecting gastropods earlier than to entomology. From the sphere where you communicate, it is not very far! In this you are wrong, but not the point! I will be glad to meet you in person, thanks to the fact that we are in Moscow.
Sincerely yours!

but what I noted: epioloides years go from 7 to 10 days in total.

In the 90 - ies of the last century, the first capture was on June 30 (male), the last on August 5 (female). I understand that the weather changes from year to year, but still they probably don't fly every week?

And here's the question. On one colony - a short period. But what to do with the August, or even September finds....2nd generation? Wintering individuals? I already wrote that I regret that I did not continue my observations!

Dolichovespula media.

It is strange that it has such well-developed stripes on the pronotum along the scutum and there are no stripes at all along its anterior edge, I have not come across such a color with us.

IMHO this is not D. media-clippings on the inner orbits of the eyes are yellow only from below + other color, although it varies...
Compare it with mine again

and full face

What about the dark-legged willow tree Dolichovespula sylvestris?

Question: Has anyone seen publications on biology and ecology: Xylocopa valga Gerstaecker, 1872 and Xylocopa violacea (Linnaeus, 1758) indicating their preference in the breeding substrate?.. like valga in old wood and violaceus in the soil???

Are there any modern signs in the difference between these similar species? To my surprise, when I looked at the NCBI GenBank, I didn't see any mention of Xylocopa valga at all!?? Only violaceus and pygmy (according to pygmy everything was perfectly studied/described by Malyshev, 1947-but is there a scan of his article?).

They nest in the soil only if there are roots there. There was one publication here, not very serious of course, but it may come in handy.

Compare it with my
A. M. B. on the dark-legged willow Dolichovespula sylvestris?

This is almost exactly D. media - D. sylvestris does not have red spots on the sides of the prothorax.
As for the previous image, I wrote about a sufficient degree of reliability... The degree of light coloration in Vespidae is a very unreliable determinant, as it is subject to many external factors. The real differences are related to the sculpture of the sides of the pronotum and the front edge of the platypus.

It is strange that it has such well-developed stripes on the pronotum along the scutum and there are no stripes at all along its anterior edge, I have not come across such a color with us.

I have seen instances of D. media with complete transitions from very bright with an abundant red pattern to almost black with reduced light stripes.
I repeat once again - the degree of development of a light pattern is not a reliable determinant. Look for differences in the sculpture, they are more stable.

In Moldova, in the region of Tiraspol, I have observed X. valga nesting in dried-up sections of the trunks of old silver poplars almost a meter in diameter.
In the Crimea, on the territory of the Karadag Nature Reserve, I saw both X. valga and X. violacea nesting in an old woodpile.
The report of Xylocopa nesting in soil is highly questionable. This is most likely either a mistake or the result of sloppy observation.
Unfortunately, the nesting of X. iris was not observed. However, to be honest, I never looked for it.

As for "modern signs", look at page 42 of this forum for the original key, which I once specially compiled to avoid signs associated with pubescence-URL #2079

I have seen instances of D. media with complete transitions from very bright with an abundant red pattern to almost black with reduced light stripes.

I've seen this too, and in one nest that I had in my childhood on the window. This is not about the degree of development of the drawing, but about the pattern (if I understand this term correctly). If the oblique band that runs along the pronotum along the border with the scutum is well developed, then the transverse one should also be visible (as in the photo of the female in IchMan). If the transverse band is strongly reduced, then the oblique band is poorly developed (as in the male in my photo). Therefore, I think that alexandronikos has a different look in the photo (I don't know which one, but not D. media).

Heh, it's quite possible. By the way, there are not so many options. More precisely, two. Either D. media or D. sylvestris (D. intermedia is not considered, because its range is different). It is too early for nesting parasites, and other species of the genus with a well-marked stripe on the lower ones. But all the same, I would undertake to judge reliably only by the instance.
I just picked up the box with D. media and realized that your assumptions about the pattern are not entirely accurate. There are specimens with normal lateral stripes and reduced transverse stripes, some with almost completely disappearing stripes, and some with a well-defined transverse (even solid) with weak lateral stripes. So, I don't trust drawings and pictures...

According to the shape of the frontal spot, it is D. sylvestris(Illustr. Bestim...Wolf, 1986).

Why are people so trusting?
Yes, neither the shape nor the size of light spots are essential for reliable determination of vespina species. They are so variable that taking them into account, you can get into a gap... Only sometimes there are stable differences in the type of drawing (pattern).

In D. media, oblique folds are developed in the lower corners of the pronotum, and in D. sylvestris, the apical part of the platypus is densely dotted. This is true, but the color is not...

P.S. Heinrich Wolf is a very nice grandfather (even in ' 86, he was already one). He mainly worked on Pompilids, but was never a vespidologist. Sorry...

Maybe one of the bees can be identified?

I completely agree with you that for a reliable definition, you need good "couplets". But here we are talking about photos of the OS, where the "oblique folds" are not always visible. And even you sometimes use a drawing on the body of an insect.for identification purposes. I will not say " for " Dolichovespula, but the European species of the genus Vespula can even be 98% determined up to the species, using 1-2 types of drawing. As for Wolf's" grandfather, " I'm sorry, but I don't agree with you.

  


Thank you in advance!

Probably.I don't know how to read photos.

I still prefer reliable definitions. Even from the photo. If I'm not sure, I write about a certain level of confidence.
As for the drawing, I do not use its individual elements, but a certain general type of drawing that has developed in my head as a result of studying mass material (or, if you like, a "pattern", as my colleague Alexander Vateryga called it).

Further, regarding the European (!) species of the genus Vespula. Let's say you can easily distinguish V. austriaca (Panzer, 1799) or V. rufa (Linnaeus, 1758) from others. And how many of them are left? There are only two species – V. germanica (Fabricius, 1793) and V. vulgaris (Linnaeus, 1758). And that's where the problems start. There are so many variations in the pattern even within a single population that it is impossible to guarantee an accurate definition based on it. And the description of, for example, V. vulgaris var. pseudogermanica (Stolfa, 1932) becomes clear, the abdominal pattern of which is almost identical to that of the "typical" V. germanica. By the way, the pattern on the trim is also not a necessary difference. In these species, even such a" good " sign as the shape of the basal mandible prong is reliable only for female queens, while in working individuals it "walks".
Well, if you expand your view of the entire range of species, then with V. austriaca and V. rufa, serious difficulties may arise. And here the character of pubescence of the 1st tergite of the abdomen and hind legs is a real help.

Finally, about X. Wolfe. I don't understand what you disagree with. With the fact that he is a grandfather, with the fact that he is cute, or with the fact that he is an expert on pompilids?
Well, a person over 80 years old is not ashamed to call a grandfather. Moreover, this is the case in reality.
As for the second one, I was left with exactly this impression. About 20 years ago, he came to Moscow with his wife (or rather, on the contrary, his wife, as a specialist in urban architecture, brought X. Wolf with us ), and we had a wonderful week.
Finally, about specialization. Yes, at X. Wolf has written extensively on various groups of hymenoptera. But mostly these are lists, biological notes, or a wonderful selection about gynandromorphs. But the researcher, almost half of whose more than 250 publications are devoted to the taxonomy of pompilids, is for me a specialist in this particular group.

Tell me, please, what is the name of the beauty on the willow flowers. And is it possible to determine the type of bumblebee? Thank you. Sverdlovsk region, Karpinsk, May 2013

female Saxon wasp on a willow tree.

a female Saxon wasp sits on a willow tree.

Please make some arguments.
And then people have already broken a lot of copies.

Please make some arguments.
And then here people have already broken a lot of copies.

The photo clearly shows the characteristic yellow stripes and color of the abdomen (partially), which is quite typical for the Saxon wasp. + date of shooting, early spring - only females fly during this period. This can't be a medium or forest female. The average female is easy to distinguish: it is very similar to the working hornet in color. Female forest wasps have a characteristic anchor yellow color in their coloration, but in the photo we see a not bright yellow color, which is another characteristic feature of female Saxon wasps. Here's my picture of a female Saxon wasp for example. This female also feeds on willow trees.

I wouldn't agree. For example, there is a specialist who has a lot of work on burrowing wasps, but he can also tell you something about vespulae, Or is he only a specialist in burrowing wasps for you?

And what is there "characteristic" in the stripes and color of the abdomen? I mean, what exactly is typical of D. saxonica?

+ date of shooting, early spring - only females fly during this period.

Sorry, but the female founders of almost all European species of vespin and polistin fly out in early spring (April-early May). No one was talking about workers or males.

This can't be a medium or forest female.
The average female is easy to distinguish: it is very similar to the working hornet in color.

But not always. Quite common and melanists without red spots and with a uniform pattern on the segments of the abdomen, which is dominated by black.

Female forest wasps have a characteristic anchor yellow color in their coloration, but in the photo we see a not bright yellow color, which is another characteristic feature of female Saxon wasps.

Again, this is not true. The "brightness" pattern of almost all European Dolichovespula species varies over a wide range. With the possible exception of D. intermedia, which has a yellow color, indeed, always (?) bright (at least, this was the case for those instances that I happened to see).

Here's my picture of a female Saxon wasp for example. This female also feeds on willow trees.

If you are sure that it is D. saxonica that is on your site, then see for yourself how different it is from the wasp that is depicted in the image under discussion-URL #4456.

P.S.
Actually, it is useful to read the previous comments before expressing your categorical opinion.

Are you not confused, for example, by the complete absence of a dark spot on the trim panel? But in D. saxonica it is always present, although its shape is variable – from an arrowed medial band to a "Ukrainian" trident.

In addition, in D. saxonica, all the lower legs are yellow on the outside, while here they are clearly darkened, especially the rear ones.

So, I'm sorry, but your argument doesn't hold water.

I approve your comments. Indeed, the trim is interesting for her. Still, what kind do you prefer??? I'm more up to saxonica or wood wasp. Maybe this will help us a little - http://vespidaeblog.wordpress.com/идентефикация-ос/ ? Although the variation of color in each individual of all vespids is always observed.

Not having enough data to pinpoint, I'm stuck between D. sylvestris and D. media. For the first somewhere 60%

Hello to the community! A few years ago, I noticed in Taganrog (Rostov region) large, but what is there - giant insects that look like a wasp, but about 4 - 5 cm in size. Periodically I saw this flying monster near the house, well, it flies to itself and let it fly. But this year a whole flock of them appeared (at least 30-40 individuals) and everything would be fine - today they are not aggressive, they fly surprisingly almost silently, but from early morning until sunset they try to break through the glass in the windows (private house), the sound sometimes resembles machine-gun bursts, when a dozen individuals they pound one by one. You know, the pleasure is questionable. They fly fast, can't be photographed, and don't take dichlorvos. A search in Yandex brought up two possible candidates: scolia (the most similar, but our giant is not so "slender") or Asian hornet(but ours is not so striped).
Actually, the question itself is: Not so much who they are, but how to get rid of them? Today they swerve when approaching a person, and tomorrow they will attack and then what? Where can there be nests? When they don't hit the windows, they fly in the foliage of trees and periodically pile up near an old stump on a neighbor's plot.

Haven't you seen my sedge plants since last year? Karelia, southern part.
