Identification of Hymenoptera (wasps, bees, ants)

Actually, the topic is "Identifying e-mails" and not, say, "E-mail specialists and their interests". Bee from the Vinnytsia region under No. 4 - Sphecodes (Halictinae).

Thanks for the compliment. Most of the entomologists I mention-I knew or know personally. Popov - sorry I didn't find him, I knew his students. I don't want to argue. And to troll - I'm waiting for an apology, as well as for the anonymous person you shortened.

16. look at the presence of consobrinus and modestus, perhaps someone can distinguish by drawing, but here they clearly differ in the ratio of length and width of the cheek. In the first type, the cheeks are much longer than in the second type.

As far as I know, in consobrinus and modestus, the main color of the breast and the first tergites of the abdomen is reddish, like in Bombus pascuorum or muscorum, or hypnorum. In this one, the entire breast and almost half of the abdomen are yellow, which is the color found in some places in lucorum or hortorum. I don't necessarily have to pinpoint the exact species, but any idea? To know who to assume and then by what criteria to determine? If he gets caught again. Here is another photo of him, also of poor quality:




Or let's put it this way: in principle, it can be lucorum or hortorum?

I'm glad you introduced yourself.
I envy you for knowing or having known these entomologists personally.
At the expense of trolling, not convinced.
Anon is an anonymous person on the net, so there is nothing to apologize for here, if you associate it with something else, then everyone thinks to the best of their imagination.

PS For this, I consider the conversation exhausted.

As far as I've been digging into them, it's lucorum or hortorum, the whitish pubescence is very characteristic of males of ONE OF THEM.
it's a pity that the collection is not at hand.
ps: IMHO ,- the simplest thing is to collect males and easily pick out their genitals. If you can find something to compare it with, it's fine. On vida ...18, - I forgot, I only made a mistake with something 1 time.
In order not to spoil the pubescence, N. Balukova from Vologda used this method - in the field of all on matchboxes, and at home in the freezer. I work in the usual way, but changing the toilet paper as it is moistened-bees must be with paper! Or I stab it from below into the joint of the abdomen and chest. And also-not in a jar, but in a wide test tube with paper pressed into it.

.. throwing pictures is an unproductive activity for bumblebees, as we have repeatedly written about here.

I'm sorry, I didn't put the question quite right. It's not so important to me that each view is accurately identified for me - I thought that it was impossible to determine exactly from the photo. I wanted to be told that this one might be either this one, or that one, or less likely that one. That is, when I identify bumblebees, I will already know who to look for and who not to look for. And then I will identify some bumblebee - and they will tell me that it is found only in Turkey or in America in general As for the paper insect identifiers-they usually have much fewer bumblebee species than appear in the lists of European bumblebees that I found on some sites.

I don't see any other way to identify bumblebees other than using qualifiers (whether paper or electronic). Qualifiers are usually compiled for specific territories. If they cover large regions, then it is normal to indicate for which territories a particular species is known, so using, for example, "green" you will not be able to determine a species found only in America or only in Turkey.
Among whom to search and who not to search, you can only suggest a list of your type: Bombus terrestris, lucorum, cryptarum, magnus, semenoviellus, soroeensis. In order to understand among whom to look, and among whom not, you need to turn these comrades in your hands with the determinant. If you want to find out, I think you have no choice but to follow the advice of stierlyz, who also analyzed bumblebees himself.
In the same "green" there are quite enough species (about 50) to first deal with bumblebees, and then, if you like, already dig special literature. The" green " is not always clear how the view visually looks in the end, you can see photos of Josef Dvořák here: http://www.biolib.cz/en/gallery/dir1363/
PS In "green" some species have outdated names, new ones seem to be normally Googled.

Well, yes, it's just shaded there, it seemed to me from the photo that the pronotum, like the first tergite, has a more reddish color, especially in the first photo. hortorum also has longer cheeks in relation to lucorum and has yellow hairs on the scutellum, forming a black band on the back.
In pascuorum (in green it looks like agrorum goes), the color of the back is quite diverse, in our case it is one of the bumblebees with the most variable body color. Sometimes the pronotum is covered with a large number of black hairs, and sometimes it is dirty-white. And the abdomen also differs in color saturation from dirty white, to brick.

Hello,
Help me determine (all from Russia, Khabarovsk Krai, Ulchsky district)

Still, it is a male of Pseudoclavellaria amerinae (Linnaeus, 1758). You can check, he should have a big white lip somewhere lying around, which is not visible in the photo

The late Popov Vladimir Veniaminovich
Rasnitsyn Alexander Pavlovich

Well, why do you repeat some biographical extracts from websites? What area are you a specialist in?

I did not happen to be acquainted with V. V. Popov, but I am, although superficially (for bees are not my field), but I am familiar with his works. I mentioned bumblebees only because I have several publications by Popov on this particular topic in my library. But Popov never dealt with pompils (or wasps in general) and was not a specialist in this field.
If we talk about his domestic contemporaries, then we should mention V. V. Gussakovsky.

I have personally known A. P. Rasnitsyn for more than 35 years and I know exactly what he does. His main interests are the paleontology of the perepons, and the pompils appear here only as one of the groups for phylogenetic constructions. He was never particularly interested in taxonomy of these operating systems.
Only A. S. Lelei and V. M. Loktionov are among the current real experts on the taxonomy of pompids in Russia. Until recently, S. L. Zonstein worked in Kyrgyzstan with pompilami, but he had to leave, and now he works at the University of Tel Aviv.
I have also known all these specialists personally for a long time and have an idea of their field of activity.

I don't want to argue, especially since we know each other. Yes, it's my fault that I forgot Gussakovsky. But I've been away from entomology for quite some time, and now I'm trying to catch up. If you took my words as an insult, please excuse me.0

So who should I contact?

So who should I contact?

To Valera Loktionov, first of all. The address is in author's abstract.

Yes How do you read these passions

Valera, aka V. M. Loktionov, while warming bones in the south In Asia. And in general, I don't think that he will be very happy about some photos of his mail. I might be wrong, though.
By the way, very soon the monograph of Loktionov, Lely "Road wasps of the Far Eastern Federal District" will be published. This is almost 500 pages with keys, descriptions and color photos of all POSSIBLE types.

Hello!
Please help a non-specialist identify the insect:
MO, Podolsky district, for two days now, around 0: 00 at night, two of these comrades appear in the room of a wooden house. There is an infant in the room – I would like to know the danger of these creatures and the reason for their appearance at such a late hour for insects.
The house is 8 years old, there are no indoor plants.
Thank you.

A single fold-winged wasp, most likely from the genus Ancistrocerus.
They nest in various holes in the wood. Prey - small caterpillars. These obviously came out ahead of time as a result of the latest warming. It does not pose any danger to anyone, as it practically does not sting.

.. In the "green" it is not always clear how the view visually looks in the end, you can look at the photos of Josef Dvořák

Thank you very much! A wonderful visual aid! Thanks to it, I just realized that I might have been wrong with some views. For example, the bumblebee, which I always thought was Bombus confusus - in fact, in some cases it could be Bombus ruderarius. But again, not all the bumblebee species that we have are represented in this catalog. For example, the subgenus Psithyrus is very little represented here. I really want to say - the genus Psithyrus, which it was before, but now for some reason they were transferred to Bombus. But it is Psithyrus, probably, that can be identified from photos? They don't have any working individuals, and there doesn't seem to be much variability among males and females.
I will venture to ask for help here on these Psithyrus (I think this is Psithyrus, although again I'm not 100% sure - maybe there are males of normal bumblebees here?) But at least presumably-who could they be?

Your Bombus confusus / ruderarius may well be lapidarius, soroeensis, etc. According to the photo, female bumblebees, including cuckoos, are more or less reliably determined.

Cuckoos (as well as some other species of bees and wasps) were allocated to a separate genus, mostly on the basis of lifestyle, subsequent studies have shown that their allocation to a separate genus is not justified.

Since females have fairly stable color types and sizes, it is relatively easy to determine and it is possible to correlate defining characteristics with color, however, it should be remembered that working individuals of some, and males of most species differ in color from females, and often species are well distinguished by females, they can have very similar visual workers and males. Take a net in the field and try to explore different stations, because females usually do not fly far from the typical nesting sites of the species and in the spring they can often be seen looking for a suitable place for the nest, so you will get the largest sample of species.
Female bumblebees are already out of hibernation and, unlike most bees, fly in bad weather.
Good luck.

yeah, right now it's the same-I nailed the female - no nest! and it doesn't make much sense.
Is your conscience silent?
males are collected-although the damage is minimal, and it is really easier to determine - by the genitals.

Conscience in this case does not bother at all, now it will warm up and they will be crushed on the sidewalks and along the roads lying around, so a dozen females caught by me will not change the overall picture.

I fully agree, although the color of females is not particularly changed, but the genitals of males are the genitals of males. It's harder to make a mistake on them. However, most of them fly closer to autumn.

A remark. Well, actually, before the departure of large individuals of the second generation of bumblebees, it is better not to catch.... And after departure, it is possible to transfer a working individual to a female... However, in the autumn generation of males from this nest will not be.... But working specimens will be available!

You are talking complete nonsense, which means that you are either not well-off in your scientific interests, which prevents you from admitting to an inflated PSV, or this is deliberate trolling.

- sorry, how do you understand the thesis about "rebirth" and the impossibility of breeding males?

The idea of going to the field with a net and everything else doesn't appeal? Sorry... You won't get very far... And Psithyrus, I should say, is generally very difficult to define. And even if aedeagi pull.

in the soil between the roots of a fallen birch tree, apparently overwintered from that year, it seems that bee cocoons are soft and with pollen on the walls, 10 mm long. All the cocoons were one at a time, or occasionally two at a time. There is an option who could it be? Or you should create some conditions and withdraw them. Voronezh, mixed forest

The ones on the right are brown, these are pupariae of flies, the larvae are basically similar to webs. Try to take it out, you don't need to create any special conditions, just put it in a box and maintain some humidity, because the apartment is usually too dry.

dy flies it is clear.. where without parasites. And how long to wait until about withdrawal?

Why, the idea attracts. But there is one small detail: I have seen several species of bumblebees almost once in my life. And there is almost no hope that you will be able to see them again and catch them. Although, of course, maybe the color was rare, and not the species itself. But it is these types that attract me in the first place. Let's say that terrestris or lucorum exist in our region and are very numerous, so they are of little interest to me. We are more interested in rare species that are either not listed in our CC, or even in the bumblebee lists of our region. I managed to capture a couple of such views.


1. I assume it is Bombus (Cullumanobombus) cullumanus. I'm not sure, though. If I had caught it, I could have identified it from the caller ID. The problem is that until last year I did not see such bumblebees at all. In May 2013, I saw two or three females in one place at once, looking for a place to nest, or just flying around the flowers. A couple of them were photographed. Then I went to that place several times during the summer, but I couldn't see anything like it. There were only the usual known species. And there is no hope that this year I will be able to catch them. Can you tell me who it is-cullumanus or not? The cheeks are long.







2. Similar situation. In 2012, I saw and photographed one male, very small. In 2013, I specifically looked for this species, but for the whole year I managed to see only one working individual, also very small. I also took a picture of him. Most likely, this is the same species, judging by its color and the fact that it is smaller than all other species. I'm guessing it could be Bombus (Thoracobombus) humilis, but I'm not sure. It seems that no other species has a similar color, but humilis is also not quite the same (judging by the photos I saw). I also have little or no chance of seeing and catching this bumblebee again. Can you tell me who it is?

dy flies it is clear.. where without parasites. And how long to wait until about withdrawal?

The last time I had a megahila nest, the first bees hatched about 25 days after I brought the house

The idea of going to the field with a net and everything else doesn't appeal? Sorry... You won't get very far... And Psithyrus, I should say, is generally very difficult to define. And even if aedeagi pull.

I agree with you completely. To say that this is a light subgenus is impossible.

This is a nest of bees of the genus Colletes, and pupariae of flies, most likely, feeding on pollen, such as Miltogrammatinae.

WELL, if you want to catch and see rare ones there, then take a net and catch a LOT of bumblebees. [/quote]

Here I read here comments of many forumchan and I am surprised. Is it really unknown to anyone that many bumblebee species are included in the lists of regional and
national Red Books? Accordingly, their capture is simply prohibited by law. And if somewhere in Uryupinsk, no one is likely to pay attention to such a catcher, then, for example, in Yakutia, you can also get behind bars...

And in Yakutia, in general, catching something is dangerous for your own health and butterflies of the same. There's a nature reserve on a nature reserve.
As for bumblebees, but after all, scientists catch people and the volumes are not small. What if, say, you need quantitative indicators for research?

My collection is very small by standards, and another time I will not touch the extra "cattle" that is clearly familiar. Three or four bumblebees for a point.

Catch wasps better, bumblebees are already the best studied of all the seasons, you won't find anything new anyway. And it is only possible to identify bumblebees from photos in the case of female founders.

"...scientists also catch fish in large volumes ..."
No, I haven't heard of them, I don't know them.
