Identification of Hymenoptera (wasps, bees, ants)

Spring, of course, spring is everywhere, but it's too much like Sergievka. It wasn't filmed there?

Nah. Pavlovsk.
There is a wonderful spring flora, and it is convenient to go.

Sergievka is also very interesting in terms of vegetation, but it is not very convenient to get there from a civilian.

So this is a common thing here. At the end of last year, nothing was attached for a whole month!

8. Some kind of blestyanka. August

Chrysis sp. (possibly Chrysis bicolor)

She. But then it's not her anymore.

That's the whole point. During the shoot, I thought it was all Tiphia femorata. I shot one several times in close-up - it turned out to have red legs. And I just clicked the others to show how many of them are on one flower. And at home I already looked at the computer-ba, but they all have black legs! And I didn't take a close - up of any of them-that's how it happened! You think that they are all one species, and only at home do you realize that you were not alone!


More on these topics, please tell me.

9. Some small fry, September.





10. Also small. July





11. June






12. August






13. Probably twice as small as Ammophila sabulosa usually is. July.

So this is a common thing here. At the end of last year, nothing was attached for a whole month!

Something about our IchMan has disappeared somewhere - this is really a problem! Riders remain undefined (on the previous page)!

Then please help us identify the Penza sedge!

2. Any Tiphia ? August

3. The front is the same, but the back is different. August

There may also be male femorates

with a red ass nysson

There may also be male femorates

I doubt. In picture 2, I clearly see women's flat "assholes". And do femorata males have completely black legs? The determinant doesn't say anything about the color of the males ' legs, but I've only seen them with partially red and or brown ones. With black already goes a minute and some more.

2 - Tiphia minuta or Tiphia unicolor
3 - same Tiphia and Nysson sp.
6-Gorytes quadrifasciatus
8 - Chrysis bicolor

Unfortunately, there is little initial data for most species, and there are many similar species. So, just like this:
9 - Pemphredon sp., female
10-Trypoxylon sp., female
11-Trypoxylon figulus, female
12-Tachysphex sp., female
13-Ammophila sabulosa. This is a male, and they can be from 1.5 cm.

Please tell me what kind of creature is so wonderful?

Probably Cimbex femoratus (Big birch Sawfly)

Thanks for the definition! Still on these vespulochkam possible?

1. Some big one, probably someone's female? August (Raspberries are remontant, so don't be surprised - what flies on raspberry flowers in August)







I tried to determine the next ones myself. Please take a look - did you guess or not?

2. Vespula germanica ?






3. Vespula vulgaris ?






4. Vespula vulgaris or germanica ?






5. Vespula germanica ?





6. Vespula germanica ?

The workers of vulgaris and Germanica are correctly matured. 4 - vulgaris. I don't know the first one, we don't have any, probably some dolichovespula.

The third image from the first three is probably Dolichovespula media: Arrow-shaped yellow figure on the side of the chest, and the eyes inside are yellow.

The third image from the first three is probably Dolichovespula media: Arrow-shaped yellow figure on the side of the chest, and the eyes inside are yellow.

Evgeny, the first three images show the same individual. It is unlikely that this is Dolichovespula media - too large in size. Larger than females of Vespula vulgaris and Vespula germanica. Only slightly smaller than the working Vespa crabro-when I first saw it from afar, I even thought it was a hornet flying!

Dmitry, I must admit that I just found a fire helmet in the trash. I need help with identification myself.
As for your wasp, I simply used a simplified determinant of the genus Dolichovespula, located at: http://www.antvid.org/Vespa/Opred/Dolichovespula%2002.html
In addition to the arrow - shaped design on the chest and the yellow cut-outs of the eyes, the design of the platypus seems to me to fit the description, and the eye color - in those wasps of this species that I have seen and hope that they are correctly identified, the eyes are not black, but chestnut. The size is not very clear from the images. Maybe it's the big females that fly in the fall?
I can't say anything more, let the more experienced entomologists speak out?

Oh, by the way, here is a handy summary of wasps-here it is indicated that females D. media up to 22 mm, females Vespula vulgaris up to 18 mm, Vespula germanica up to 20 mm.
In general, this D. media is a rather rather big wasp.

And who do you think is bigger than media, apart from the hornet?

I don't know, I just shot working media a few times. They were no larger than ordinary vespulae and polistae. But maybe their females are much larger than the workers? I don't know!

In all vespins, the uterus is much larger than the workers. As far as I know, media is the largest of the Russian vespins, not counting hornets. I suspect that's why it's called that-a cross between hornets and all the others.

Evgeny, the first three images show the same individual. It is unlikely that this is Dolichovespula media - too large in size.

And yet it's Dolichovespula media.
I can even specify that this is a working individual.

And who do you think is bigger than media, apart from the hornet?

Well, for example, females of Dolichovespula adulterina, D. omissa, D. pacifica or Vespula koreensis are quite comparable to Dolichovespula media of medium size.

No, not all vespinas have "queens" larger than the workers - for example, in Vespa analis, the workers are noticeably larger than the "queen".
As for the name, it comes from the Latin adjective medius (= middle) and is related to the fact that this wasp was originally described by Anders Jahan Retzius as a subspecies of the common hornet-Vespa Crabro medius Retzius, 1783. At first glance, both in size and appearance, D. media is so similar to the medium-sized V. crabro workers that it was not until the mid-twentieth century that this species was assigned to the genus of long-cheeked wasps.

Well, for example, females of Dolichovespula adulterina, D. omissa, D. pacifica or Vespula koreensis are quite comparable to Dolichovespula media of medium size.

But it's not bigger. Yes, and the last two Pedevikia baits up to 22 mm for media, for all others living in the Russian Federation - less. I haven't seen them myself, though, so I might be wrong. The bottom line is.chto Penzuit expressed doubts that this is a media outlet, because it is too large. I objected that this criterion is untenable, because the media is already the largest.

Well, Pedevikia is not a decree for me.
I'm talking about what I've seen and have. Of these, only adulterine is slightly less, but omissa is not inferior at all. In addition, only the "queens" of media are large, and the size of the workers varies (as, indeed, in other vespinas, where they are present).

But it's not bigger. Yes, and the last two Pedevikia baits up to 22 mm for media, for all others living in the Russian Federation - less.

What is there 22 mm-somewhere under the thirty was! And even a working one - and what are their females like? Although, for example, in Vespula vulgaris, I still don't distinguish females from workers, even if they are sitting next to each other. Then they tell me from the photo.
I wonder if wasps don't have summer females. Only wintering ones?

In general, we agreed: dolichovespula, which could be called too large to be a media outlet, is not known from the territory of Russia. etc.

Penzuit, fear (as well as admiration) has big eyes. 30 mm is even a very decent size for the uterus of an ordinary hornet (although far from a record). Next time, catch and measure. In Vespula vulgaris, the uterus differs from the workers very much, you will see it live once, you will never confuse it. It has much larger dimensions and different proportions.

What do you mean "summer females"? Queens, or founding females, are the same color in winter and summer. Here wintering workers, which, by the way, are also females, do not happen in temperate climates.

Just for fun, I measured the size of two Vespa crabro hornets from my collection. Working individuals. 29 and 31 mm.
Two Dolichovespula media 22.5 and 24 mm. I don't really know if they're female founders or workers. These two wasps are not straightened, so there may be errors in the measurement.

 
In Vespula vulgaris, the uterus differs from the workers very much, you will see it live once, you will never confuse it. It has much larger dimensions and different proportions.

The first photo shows a female Vespula vulgaris, while the second shows a worker. No matter how much I break my eyes , I don't see any difference. Take my word for it - and there was no difference in size. When I removed the uterus, I was absolutely sure that it was a working one, since it was no different in size from the others, which also flew here in large numbers.







In Dolichovespula saxonica, too, I can hardly distinguish females from workers, and in Polistes dominula I can hardly distinguish them. Many times I have watched a female build a nest, and soon there are many just like it, both in color and size. Polistes nimpha, on the other hand, has significantly larger females than the workers.




Speaking of which, whose male is Polistes dominula ?





You've got it all figured out about the summer females, you're just being silly. You could just say, " No, unlike bumblebees, wasps don't have summer females."

Well, here both Vespula vulgaris workers. Females are much larger and with more characteristic (and less variable) coloration. But polistov females from workers really do not distinguish. Even in Polistes nimpha (only the first cohort of workers can be distinguished by size, and then in the presence of a larger female). The photo is indeed P. dominula, but not a male, but a female (or worker). I didn't understand about summer females at all. If it is meant that future female founders can fly outside their nests in the summer with males, then this happens in wasps, which is very typical for Vespula rufa and various Dolichovespula. Only in V. vulgaris and V. germanica, they appear much later in the fall (I don't know about hornets, we don't have many of them, and you can't tell the difference between females and workers in polistov anyway).

That's all very well said.
I can only clarify that Vespula rufa and most of our Dolichovespula (well, even for parasitic species) are characterized by a short cycle of family development, so they have young female founders fly out in August. Other Vespula and Vespa crabro have a long cycle, with a new generation of females and males flying out by the end of September.

Thank you all for the clarification!
About the first photo of Vespula vulgaris - you yourself identified it to me as a female! If you're interested, take a look for yourself - it was exactly one year ago!
Well, they misled me, and I almost ruined my eyesight-while comparing two workers!
In fact, I understand that when there is a stream of photos, it is very easy to make a mistake if you do not pay much attention. I myself had such a case: I was once asked to identify a grasshopper from a photo. It was a very ordinary female Tettigonia cantans, with an ovipositor on its butt. And I'll take it and write it down: "Male singing grasshopper" (required a Russian name). I just wrote it automatically - I knew perfectly well that it was a female, but my head was full of something else, and I wrote "male" instead of "female". Then they asked me: "And the saber on your butt - isn't that an ovipositor?" Of course, the ovipositor-I knew this when I was still in kindergarten. But here is my hand - my enemy-so take it and write!



I found a female Vespula vulgaris of very poor quality - indeed, the drawing is different! I don't remember about the size - it was removed a long time ago!





Here is the nest of Polistes nimpha - here the female is larger than the workers. But this is probably because the workers of the first cohort, and the next will be larger.






And here are two working Dolichovespula media that baffled me. Because of them, I had the wrong idea about this species. They were taken in different years, but I definitely remember that they were not large, they were comparable with Vespula vulgaris workers, at most with Vespula germanica workers. That's why I thought Dolichovespula media was a shallow view. And then all of a sudden there's this huge thing flying around - I wouldn't have thought they'd have such a variation in size!






Now about the summer females. I may have been confused and have the wrong idea about this, but I will tell you how I was told myself.
I used to think that the female founder of bumblebees first lays fertilized eggs, from which workers are born first, and then some larvae, due to special feeding, then turn into queens-into new female founders. At this time, the same founder suddenly begins to lay unfertilized eggs, from which males appear. I once asked an entomologist about this, who seems to be an experienced one, and he told me that this is not what happens in bumblebees.
At first, everything is so-the female lays eggs, from which workers first appear, and somewhere in late June or July, the so-called small queens, or summer females, appear. I don't know why they are called small queens, since they are usually larger than the wintering founder females. These small queens (summer females) live in the adult state for only about a month-in July or August, lay their eggs in the same nest in which they appeared, and it is from their eggs that males appear. Naturally, their eggs are unfertilized. As for the female founder, she carries only fertilized eggs, since each of her eggs touches the sperm sac when leaving, and therefore males are never born from her. By late summer or early fall, some of its larvae turn into new founder females, and around this time the old queen dies. Thus, wintering queens (female founders) live in the adult state for almost a year, and small queens (summer females) - only a month.
These summer females are often larger than the winter ones, and some color details may differ. For example, summer females of Bombus terrestris very often do not have yellow hairs on the pronotum, which are almost always found in female founders and workers of this species.
Well, that's what they told me. Not being an entomologist, I can't say whether this is true or not - judge for yourself.

The female founder lays both fertilized and unfertilized eggs. Workers in bumblebees are normally developed females and can lay unfertilized eggs, but the founder female usually suppresses their activity with pheromones. In addition, eggs laid by workers are destroyed physically by the founder female and the nanny workers. At the end of the season, when the female founder is old and the nest is large, her pheromone activity decreases and she cannot fully control the reproductive capacity of the nest, quite a lot of worker eggs appear. IMHO, by the time the males come out of them, they probably have no one else to mate with. Usually, the first brood of males is exclusively from the eggs of the female founder.
Bombus terrestris with a black back is var. cryptarum. It occurs all the more often, the more northerly the species lives. In the Moscow region, in the early spring, I met females of this form, those females who had a yellow sling, it was very undeveloped - not wide with an indistinct posterior border. In the second half of summer, there were also exceptionally large ones, along with large ones with a normally developed sling. I don't know who they are, the rotten workers or the young queens.

I found a female Vespula vulgaris of very poor quality - indeed, the drawing is different! I don't remember about the size - it was removed a long time ago!

This is a female V. germanica. Otherwise (as far as the OS is concerned) everything is correct.

Tell me, please, the type of bumblebee?

Two species feed on Equisetum fluviatile: Dolerus (Dolerus) cothurnatus and Dolerus (Dolerus) pratensis. Is it possible to distinguish them by photo?
In the pictures, it looks like a female and a male... Or different types?

Yes, it seems that cryptarum is now considered a separate species, and for some reason it is closer to lucorum. "Bombus terrestris var. cryptarum." - 0 results of the google search.

maybe, but nevertheless black-haired females are characteristic of terrestris

Here we go again - twenty-five! This female was identified to me as Vespula vulgaris, also here on Molbiol! I ran all my oss through Molbiol, with the exception of Megascolia maculata and Scolia hirta, which are unmistakable! And hornets, of course-Vespa crabro is unmistakable!
So I don't have much luck with Vespula vulgaris females! Two of them were so defined to me, and they never got it!

That's for sure! I noticed that Bombus terrestris is very common in the city and in suburban areas, but not very common in the forest. Bombus lucorum, on the contrary, is common in the forest zone and rare in the urban one. And black-haired females are usually found in urban areas, I did not see them in the forest - that is, they are characteristic of terrestris, and not of lucorum. Almost always, they are large in size and can be found as early as July - that is, they are hardly founder females. In addition, female founders are usually smaller than these black-haired ones. Therefore, it seems very logical to assume that males can be descended from them. Unless, of course, the female founder suppresses their eggs with her pheromones.
As for Bombus cryptarum, I also repeatedly found information that this is a separate independent type. From the external signs, it differs from terrestris and lucorum by a strong black pubescence of the head, and it also seems that the yellow band on the abdomen is on the second or even on the third tergite, and not on the first, as in terrestris and lucorum.
