Identification of Hymenoptera (wasps, bees, ants)

Can you identify anyone from these photos? All - Ukraine, Luhansk region.

Stilbum calens.

So that's what it's called - a field bumblebee.

For me, it also looks like hypnorum. But bumblebees in the photo only with a probability of seventy percent. Their stripes vary greatly.

it's all written here about your bumblebees http://elar.urfu.ru/handle/10995/1905 or better yet, go to the Flora and Fauna Library http://herba.msu.ru/shipunov/school/sch-ru.htm

No

With such a shape of the abdomen, is there anything other than stilbums? It's a pity, the venation of the wings is not visible. And if stilboom, then only this one, the second type has a greener belly, and this one also happens (not red) when it's dead, I checked it myself.

Yes, it is sama

I also once thought that it doesn't happen. They all change color when they dry in the sun - I agree with you here, I don't want to prove anything, I just thought at first that it was Stilbum, too. Alas, it's not him. When you start to encounter wasps glistening - it becomes clearer and clearer, you start to understand. What's Stilboom's head like?Wing venation, End of abdomen, punctuation?

There is no head here and the venation is almost invisible (the main thing is that the radial cell is not visible). Okay, we'll have to compare the photo with the copy on occasion, at least for the dotted line...

The punctuation of the body, especially the abdomen, in Stilbum is much smaller, and the 3rd visible tergite is almost smooth. The scutellum is flat, and the rear scutellum protrudes far back.
It's just a headless instance of some kind of Chrysis. By the way, when spangles (and indeed most "metallized" insects) dry out, they do not lose their color, since it is determined not by hypodermic pigments, but by the special structure of the outer layer of the cuticle (approximately like that of morphids).

And there can't be P. associ, or this species is also absent in Ukraine?

With this view, I still don't understand. I didn't see him alive, and L. Rusina told me that she couldn't tell him apart herself.
I'll get some well-defined material from Europe, then. maybe I'll figure it out.

I don't understand how I could not pay attention to the head.

Compared with the collection - really not Stilbum. As for the loss of color, I was referring to cases when the wasp dies itself in special conditions (at high humidity - ?). Apparently, then, the tergites, after all, somehow fade. I have found specimens with this tarnished tergite coloration that died in sealed cells of Katemenes flavigularis. And when I caught the same species with a net and smeared it with ether, the color, of course, was preserved.

I forgot to mention, the species were Stilbum calens and Chrysis rutilans, normally brighter, and from the cells of the host wasps-as dim as in the photo above.

I have the same nonsense, I couldn't figure it out, I only noted for myself that Polistes nimpha we have two "species" - large, almost like P. dominula, and small, like P. gallicus, only, of course, more stocky.
We'll consult with you later, if you'll excuse us.

In fact, the range of size variability in almost all our types of polysts is approximately the same. Well, maybe P. biglumis is somewhat smaller on average. The largest are P. atrimandibularis and P. sulcifer. But everything is clear there - the nest parasite must be larger and stronger, since it is necessary to fight with the hosts. Body size is mainly determined by nutrition and the degree of parasitization, primarily by ticks. By the way, the severity of yellow coloration also depends on ticks - the higher the parasitization of larvae, the stronger the yellow coloration in adults is (I do not compare the northern and southern populations, it is also more or less clear there - the northern ones are darker on average).
So the size and color are not the most suitable signs for distinguishing between types of polysts.

I just noticed that they have different nesting methods: small ones nest in plants, while large ones nest in attics. Maybe, of course, there are more mites on the plants, I don't know.

Have you ever thought that the causal relationship is reversed? Namely, wasps from nests in shelters are larger because they live in more favorable and protected conditions.
Well, both of them "catch" ticks on the visited plants.

Perhaps the cuticle of those who died in this way is simply "dirty". It can be some layers up to a thin layer of mold.

Cerceris kaszabi Tsuneki, 1971

Krasnoyarsk Territory, Minusinsky district, Malaya Minus settlement. Female, about 12 mm. The hairs on the crown of the back and the 1st tergite are long. Sides of the gap. the legs are leathery in numerous, weakly expressed wrinkles. 1st tergite in clear, not dense spots, shagreen.
Perhaps this is Symmorphus angustatus Zett. I have a copy signed in the same way, but there are differences in the dotted line of the 1st tergite and in the location of the yellow spots.

Please help me with the hornet.

What are your doubts, hornet as a hornet-Vespa crabro

What are your doubts, hornet as a hornet-Vespa crabro

Well, yes, the usual hornet. It differs only in a pair of longitudinal brown stripes on the mid-spine, which are not characteristic of" our " hornets.
Therefore, I suspect that the author had in mind more accurate information. The fact is that the Germans on their territory distinguish several "subspecies", which in reality do not have any giatus. Accordingly, they are no more than color forms that differ in the degree of severity of brown markings on the chest and abdomen.

Have you ever thought that the causal relationship is reversed? Namely, wasps from nests in shelters are larger because they live in more favorable and protected conditions.

Of course, it occurred, but for some reason it is so well expressed only in Polistes nimpha, while P. dominula on plants and in shelters are approximately (that is, without using statistics) the same.

Perhaps the cuticle of those who died in this way is simply "dirty". It can be some layers up to a thin layer of mold.

I came up with the idea that in this case they do not fade (that is, the red color does not turn greenish), but simply do not completely harden before they die, which in theory should affect the optical properties of the cuticle.

And also in the shape of the body, the depth of the longitudinal furrow on the first tergum and in the shape of shoulder angles. I don't understand anything, it seems that there are parietal fossae and a longitudinal furrow on the first tergum, but somehow it doesn't look very similar to Symmorphus at all.
Unfortunately, I have nothing to compare it with, S. angustatus is not in the collection, but it is clearly not the same type that you posted last time.

Muddy group...What else can I check for? Still, I have a copy in my hands, I can turn it around, check it out. I have here their group of such handsome people is worth, which then one, then the other is not similar and the feeling that the determinant of green and green is not enough for me...
maybe ancystrocerus then?

South of Krasnoyasrky Krai. About 12 mm. The female. The platypus is without teeth, narrowed at the top with a small notch. The hairs are silvery-golden. The 3rd us. is approximately 2.5 times longer than the width. The punctuation of the head is clear, with larger and more scattered points towards the back of the head. The punctuation of the mid-spine is thick, clear, sometimes I form short tangled wrinkles, to the scutellum more discharged, shiny. The sides of the chest are covered with thick spots, sometimes forming wrinkles. Sides of the gap.the segments are not separated by a clear edge, only at the top the transition from the sides is raised in the form of irregular cells. The abdominal punctuation is rough, with more points on the first tergite than on the second. Bottom of the middle breast with a transverse keel.
As an option Ectemnius schlettereri

What do you have for an exchange from Germany? Except for butterflies and bedbugs.

thank you all !
and this one is the same ?
found in coniferous forest under moss on the ground

thank you all !

also a hornet-Vespa crabro

but no you are slightly mistaken, in Germany there are so many subspecies here is one of them Vespa crabro germanica

but no you are slightly mistaken, in Germany there are so many subspecies here is one of them Vespa crabro germanica

Dear Andrey,
First of all, try to understand such taxonomic categories as genus, subgenus, species, and subspecies for yourself... I did not just point out the absence of hiatus between the German Vespa crabro populations. Subspecies must be somehow isolated from each other in order to be real. This is not the case here, and there are smooth transitions between German hornet populations.
So, do not believe what the burghers write, who willingly or unwittingly want to show the uniqueness of their fauna.

For you, I will give you a list of the names under which the common hornet was described, but later reduced to junior synonyms (in chronological order).:

Vespa Crabro Linnaeus, 1758, "Europe".
= Vespa vexator Harris, 1776, "England".
= Vespa Crabro major Retzius, 1783,?.
= ? Vespa pratensis Geoffroy, 1785, France.
= Vespa Crabro germana Christ, 1791, Germany.
= Vespa Crabroniformis Smith, 1852, "Northern China".
= Vespa crabro var. borealis Radoszkowski, 1863, "Russia". Junior primary homonym Vespa borealis Kirby, 1837, Vespa borealis Zetterstedt, 1840, and Vespa borealis Smith, 1843.
= Vespa crabro var. anglica Gribodo, 1892 (1891), Italy. Junior primary homonym Vespa anglica Smith, 1843.
= Vespa oberthuri du Buysson, 1902, China.
= Vespa flavofasciata Cameron, 1903, Japan.
= Vespa crabro var. tartarea du Buysson, 1905 (1904), Japan.
= Vespa Crabro var. Altaica Perez, 1910, Altai.
= Vespa Crabro var. Caspica Perez, 1910, Azerbaijan (Talysh and Lnkoran).
= Vespa crabro vulgata Birula, 1925 (1924), Western Europe.
= Vespa crabro meridionalis Birula, 1925 (1924), Transcaucasia and Transcaspia.
= Vespa crabro chinensis Birula, 1925 (1924), China. Junior primary homonym Vespa chinensis Fabricius, 1793.
= Vespa crabro var. birulai Bequaert, 1931. Replacement name for Vespa crabro chinensis Birula.
= Vespa crabro var. gribodoi Bequaert, 1931. Substitute name for Vespa crabro var. anglica Gribodo.

PS For an example from other operating systems... In the well-known species Chrysis ignita, more than 20 color forms were described in the rank of varietae and subspecies. All of them later also appeared in the list of junior synonyms.

by the way, I found an article that there are 2 varieties in Germany-Vespa crabro germana and Vespa crabro crabro
http://www.aktion-wespenschutz.de/Wespenar.../horniUnten.HTM

Please help me identify the sawflies!

1. [attachmentid ()=154610][attachmentid ()=154611] Moscow region, Pushkinsky district, 1.07. Rhogogaster of the viridis group?

2. [attachmentid ()=154612] Moscow region, Pushkinsky district, early August Tenthredo sp. ? What types can there be?

3. [attachmentid ()=154613] Moscow region, Pushkinsky district, 12.07 Tenthredo vespa?

4. [attachmentid ()=154614][attachmentid ()=154615] Pushkinsky district, Moscow region, 8.05

5. [attachmentid ()=154616] Moscow, 24.05

6. [attachmentid ()=154617][attachmentid()=154618][attachmentid()=154619][attachmentid()=154620][
attachmentid()=154621] Moscow region, Pushkinsky district, 2.08 Tenthredo sp. ? What types can there be?

Thank you in advance!

No one will look? At least up to the subfamily-tribes!(Page 72, message 3593)

Definitely not Symmorphus angustatus, I found it in my collection.
It reminds me of Ancistrocerus parietinus or A. oviventris (if you close your eyes to the longitudinal furrow on the first tergum). They have such notauli and parietal fossae, and the characteristic feature is a very wide second segment of the abdomen. As for the furrow , you've seen that it can even be found in Odynerus (or Gymnomerus, I don't remember what it was).
Check the second sternite from the side, its leg obscures.

Dolichovespula sylvestris ?
Germany
