Identification of Hymenoptera (wasps, bees, ants)

Good evening! Here are some more summer photos, help who knows what!
Everyone who can be found from different angles, but, in principle,it would be nice to decide at least up to the gender.
All ours, Rostov. Waiting for help!pg [/img] [/url]

Thank you very much in advance!

Is it not possible to specify the dimensions for bee species?

Thank you very much in advance!

With wasps of course you can get to the genus:

5 Philanthus sp.
6 Cerceris sp.
4 Oxybelus or what?

But I hope that a real professional will come and determine exactly and up to the species.

Alex, it's time to become a professional yourself! You may well be able to do this. Find a good reference collection from ZIN (start with Heb. Parts of Russia), some literature (in English and German) and that's all! We are waiting for the first work, for example, the List of Apidae of the Leningrad region.

I'm not so bad! Rent an article per month! From European topics, I prepared an illustrated list of proctotrupids of the European part of Russia. I will give it to Kavkaz Ent Bull.

Cool! Well done, Vitya, congratulations!
I've been slowing down a bit lately.

Is it not possible to specify the dimensions for bee species?

No, that was six months ago... And so, from memory, 3, 7, 8, 9 are small, about 10 mm, the rest are larger. No. 2 is the largest, about two centimeters. I can't be more precise..

1A and 1B are different species (even different families)
1B this is some kind of Andrena, female
1A male Megachilidae, maybe Osmia of some kind?
2 it is very bad when the wing venation is not visible, but I will risk it-Andrena? Andrena carbonaria or some similar species.
3 female Halictus sp.
7 male of some member of the subfamily Halictinae (Halictidae). For example, males of Lasioglossum albipes or Lasioglossum calceatum have a similar appearance (see the photo here http://www.atlashymenoptera.net/page.asp?id=45, but to identify halictids from the photo is of course....

I'll probably throw in my own philanthropists, too.
if possible, please confirm
1. Ph. helmanni Eversm. male

2. Ph. triangulum male

3. Ph. triangulum female

4. Philanthus coronatus F. male

5. and here's another Palarus variegatus F. female

I'll probably throw in my own philanthropists, too.
please confirm if possible

That's right, but fix it:

1. Male Philanthus hellmanni (Eversmann, 1849)
2-3. Male and female Philanthus triangulum (Fabricius, 1775)
4. Female Philanthus coronatus (Thunberg, 1784)
5. Female Palarus variegatus (Fabricius, 1781)

In the name, each letter has a value. In addition, parentheses indicate that the species was originally described in a different genus.

Thank you, I didn't know about parentheses. In fact, I have quite a lot of material on oss, we don't have enough time to do everything.And there are many controversial ones. Someone sent a photo to Mikhail Mokrousov.
Alexander, maybe you are also interested in some individual genera from Siberia, in particular the Krasnoyarsk Territory.
Can you help me find out more about the Pemphredon genus or help me find out more about it on the web?
Thank you in advance.

When I was listing the vital literature, I somehow forgot to mention the MOST important one, which should be the" bible " of any taxonomist. This is the International Code of Zoological Nomenclature. It is a must-have and must be read and mastered, so that there are no overlaps in the work.

Further, fortunately for you, just for the genus Pemphredon there is a fairly recent work on the world's fauna:

http://www.biologiezentrum.at/pdf_frei_rem...2_0905-1019.pdf

But, in principle, our two qualifiers (for the European part and for the Far East) should be enough to determine the species throughout Russia.

And please do not stick insects on pins with a curved ear. I understand that they are not always enough, but in any case, it is better to bite off the ear than to get caught on it and lose the copy. If there is a shortage, it is better to use sewing needles instead of office pins. By the way, in the British Museum insects are impaled on pins without an upper thickening. This is not always convenient, as you have to remove the specimens with powerful tweezers. But still, don't get caught up in anything.

oh, still in Russian )))))
thank you very much
for the pins..well, it's difficult here, everything is already pinned up. the only thing that I clamp the curved ears with pliers.

No, in Russian only our two. In fact, most publications on stinging hymenoptera are now published in English. So I strongly recommend that you master at least up to the level of reading keys (this is not difficult, by the way. I don't want to read Shakespeare. There is, however, a very large reservoir of Crabronini, which Jean Leclerc thoroughly studied. So he basically refused to use any other language than French... Well, the luminary has the right to choose.

And about the pins, that's for the future.

Pins with a curved ear are a material from our Soviet past. I also have a lot of old fees on these pins. Inconvenient of course. Now only on entomology.

Alexander, what do you think about Jacobs (2007) Die Grabwespen Deutchlands? And also the German - language three-volume Scheuchl-Illustrierte Bestimmungstabellen der Wildbienen Deutschlands und Osterreichs? How good is this for identifying our fauna in general and in particular? I still can't get my hands on bees, but Lomholdt (1975-1976) almost always helps out on sphecoid ones, since I only deal with the northern European part of the country, where there are not so many burrowing wasps as in the south. Spilomena was made in 2000 by Veli Vikberg, and I still have difficulties only with the definition of small black Crossocerus - what can you advise on them?
And also on road wasps and spangles - has no one in Europe ever been able to do something after Wolf (1972) and Linsenmaier (1959), or do I just not know this literature (I didn't dig much, I would keep track of ichneumonids...)?
I am only interested in the possibility of defining "love and know your land" for regional faunistics , English would be preferable.

Almost all of the above information is quite up to par. Well, maybe, but Ole Lomold is already a little behind. The only thing that should not be forgotten is that any regional work is a priori "worse" than a wider one. Yes, regional works can be more convenient and easier to use, but these advantages are usually achieved at the expense of compromises, i.e. by reducing the number of taxa considered. As a result, you may miss interesting finds that are simply not included in the regional keys. I have, for example, this happened when a species of Crossocerus was found in Primorye, described in Taiwan, and in Moscow another, but described in Japan.
Almost all" our " Crossocerus species can be easily identified using V. Marshakov's well-functioning keys. Unless with the exception of some "rare" ones (for example, those mentioned above), as well as locally common ones.
Unfortunately, there is almost nothing modern and general about pompilids and spangles. Those who want to work with them appear periodically, but then safely disappear. So these groups "hang".

I apologize for the not very good angle, this is also

Yes, it is defined correctly. But there are obvious problems with the floor. This, judging by the shape of the antennae and the color of the abdomen, is a female.

In fact, Apocrita females and males are quite easy to distinguish by the number of visible abdominal segments (6 in females and 7 in males) and the number of antennal segments (12 in females and usually 13 in males, with rare exceptions). In addition, the antennae of males are often modified (different length, changed shape, there are thyloid bumps or special fields), which is associated with the development of chemoreceptor sensory areas. The exception is, perhaps, the real spangles (Chrysidinae), in which only 3 segments are visible, and the antennae of both sexes are indistinguishable.

Thank you. the photos were taken a long time ago, at that time I could have flown with the floor. )) I searched for my photos here using Pemphredon, but I can't find them ((
some of them are on pages 18 and 20, but some of them are already redefined there. I am most interested in the genus Psen, and maybe not him and Ectemnius

I searched, but found only what you call Psen. In fact, this is a different genus. The Psen has a sharp spike between the antenna bases, but here there is only a thin edge. It's either Mimumesa or Mimesa. The first genus has mesopleurae (i.e., mid-thorax flanks) with a longitudinal epimeral (otherwise, scrobal) furrow separating the upper semicircular part with a smooth surface (almost like Psen). In the second case, this furrow is not pronounced, and the top of the mesopleur is usually thinly ribbed and opaque.
In both genera there are completely black species, but their physiognomies are almost impossible to distinguish. Try running it, for example, using this key:
http://ashipunov.info/shipunov/school/book...zakhstana_2.pdf

Oh, I have Kazenas, I just didn't refer to this source. Thank you, I'm driving it.)))

That's what I wanted to ask you about.Pemphredon rugifer or lethifer..I understand that it is so difficult to determine. I can't find a photo of the head on the front.

the one really close to the genus Psen was clearly visible that the one on page 20 has 3 radiomedial cells, the same 2

That's what I wanted to ask you about.Pemphredon rugifer or lethifer..I understand that it is so difficult to determine. I can't find a photo of the head on the front.

More like Pemphredon rugifer. But you need to look not only at the shape of the platypus, but also at the propodeum and the top of the pygidial field.
In rugifer, the sculpture of the propodeum is comparatively coarser, and there is often a medial sulcus, and a pygidial field at the apex with a short medial rib.
By the way, keep in mind that the determinants "subspecies" indicated in "green" are now considered only as junior synonyms, since their defining features are unstable and are within the limits of intraspecific variability.

the magnification is small..the structure of the breast is poorly visible. Unfortunately, I don't know the structure of some parts of the os body very well. Is the propodeum an intermediate segment?? Epicnemial suture is in the anteroposterior half of the middle breast??.... in general, you will need to spend time studying the structure

The upper part of the sides of the midspine is smooth and shiny, separated by an epimeral furrow. judging by the ratio of the stem and the 1st tergum, this is Mimumesa atratina (according to green atratinus)

There will be time I want to take and show photos of Miscophus, Passaloecus, Psen ater, Gorytes, Oxibelus uniglumis and and O. dissectum, a couple of Tachysphex
determined long ago in green, there may be gross errors

tell me, Vespula rufa can be without red spots on the sides of the abdomen, I have a wasp that fits the description of this species, but without spots

there will be time I want to make and show photos of Miscophus, Passaloecus, Psen ater, Gorytes, Oxibelus uniglumis and and O. dissectum, a couple of Tachysphex

I doubt productivity in many cases. Identifying Miscophus, Passaloecus, or Tachysphex from general photographs is almost hopeless in most cases. They are also not so easy to distinguish between mounted copies with binoculars. We need very high-magnification shots of certain body parts that show the specifics of the sculpture and / or pubescence. In addition, to accurately identify males, it is often necessary to study the structure of the genitals. What kind of photos are there… I can immediately warn you that the fauna of Miscophus in Russia (and, frankly, in the Palearctic in general) is very poorly studied, and the keys are mainly based on old data. So errors are more than likely.
Gorytes is a little easier, but you also need to see the sculpture of the mid-spine, 1st tergite, and pygidial field. Perhaps this work will help:

http://www.bembix-newsletter.de/publicatio...ic%20region.PDF

Finally, the generic name Oxybelus has a masculine grammatical gender. Accordingly, the correct spelling is Oxybelus dissectus.

tell me, Vespula rufa can be without red spots on the sides of the abdomen, I have a wasp that fits the description of this species, but without spots

Yes, it can. And the farther east the specimen was caught, the more likely it is to encounter melanists – both females and, especially, males. I have an almost completely black male of this species from Kamchatka.
Vespa Schrenckii Radoszkowski, 1861 and Vespa Sibirica André, 1884 were once described on the basis of such material, which were later considered as subspecies of Vespula rufa (Linnaeus, 1758). In fact, these are just intraspecific color variations, most likely related to external conditions of development. At least in the Far East and Kamchatka, there are all transitions from strongly pronounced to completely absent red-red spots. So now these names are considered as junior synonyms of V. rufa. But black hairs on the first abdominal tergites with no black setae on the hind legs are really stable signs of V. rufa.
By the way, a similar pattern of intraspecific variability in the severity of red spots on the abdomen can be observed in Dolichovespula norwegica (Fabricius, 1781) .

The upper part of the sides of the midspine is smooth and shiny, separated by an epimeral furrow. judging by the ratio of the stem and the 1st tergum, it is Mimumesa atratina (according to the green atratinus)

Well, changing the ending of a specific name is a common procedure when changing the grammatical gender of a generic name. Psen has a masculine gender, therefore atratinus, at the same time, Mimumesa is a feminine word, respectively, the specific name was changed, in accordance with the requirements of the Code, to atratina.

In July, I went to a clearing with my children and caught a sawfly. I've never seen anything like this before. The body is about a centimeter long, the antennae and legs are yellow, the wings are transparent, but the body is metallic green, I would say grassy green, and very shiny. I can't post a photo yet, sorry. Can anyone guess what the beast is.

Almost certainly one of the Argidae, if compact, and the segments of the antennae are full.

Please help me identify the bee. Photos from the Carpathians.

Definitely, we can only say that this is a female Andrena. It would be good to specify the date and size. But even this will be clearly not enough.
