Identification of Hymenoptera (wasps, bees, ants)

strange... I have in general a bunch of wasps of the genera Crabro, crossocerus and ectemnius, well, if I missed so much here, then I think that with them I generally have a lost cause!!

No need to be sad, everything is fixable.

Crabro cribratus is out, male. The front legs are heavily modified, the extended part is almost all dark with small yellow specks, other signs are also suitable
, so I will understand these three genera

well, then, as far as possible, I will try to show my sedge of these genera. Well, if possible, if you have time, tell me, judging by this promo code, I think it will be harder here than with Cerceris

Hello. Please tell me-what kind of bees are these? "Are they males, by the way?"

Eucera probably

Crabro cribratus is out, male. The front legs are heavily modified, the extended part is almost all dark with small yellow specks, other signs are also suitable

It looks like it, but with some clarifications. The fact is that in the genus Crabro there is no species with the name “C. cribratus", but there is the most famous species of the genus - Crabro cribrarius (Linnaeus, 1758).

Linnaeus, in his first work (Linnaeus, 1758), described the species Vespa cribraria Linnaeus, 1758 (I have already mentioned that this genus initially included almost all wasps with the “typical aspen” body shape and color).

Fabricius (1775) was the first to assign this species to the genus Crabro, which he also distinguished. Since then, it has been referred to as Crabro cribrarius (Linnaeus, 1758). True, Fabritius knew that the same generic name had been published earlier by Geoffroy de Saint Hilaire (1762), but both he and most of his followers ignored the generic name Geoffroy Saint-Hilaire for quite good reasons. In the future, a peculiar battle unfolded for this name, which is discussed in detail in the review of species of the genus Crabro of the fauna of the USSR (see: Marshakov V. G. 1977. Review of genera of the Crabronini tribe (Hymenoptera, Sphecidae) in the fauna of the USSR. Genus Crabro Fabricius, 1775. Entomological Review, 56(4): 854-872). The skirmishes of scientists for almost a century and a half did not lead to anything good, but only confused the already difficult nomenclature. Therefore, in the end, the International Commission on Zoological Nomenclature [International Commission on Zoological Nomenclature, 1943:91 (Opinion 144), and 1994:59 (Opinion 1754)] removed the name Geoffroy Saint-Hilaire, while the name Fabricius was retained as valid for this genus. By the same decision (ICZN, 1943: Opinion 144) Vespa cribraria Linnaeus, 1758 was designated as the type species of the genus Crabro Fabricius, 1775. Here you can even see what a typical instance of Linnaeus looks like: http://www.linnean-online.org/16756/

As for the name "C. cribratus", it was mistakenly used only 3 (!) times:
- Eversmann, E. 1849. Fauna Hymenopterologica Volgo-Uralensis. Fam. III. Sphegidae Latr. // Bulletin de la Société Impériale des Naturalistes de Moscou, 22:359-436. (как Crabro cribratus)
- Tsuneki, K. 1972. Ergebnisse der zoologischen Forschungen von Dr. Z. Kaszab in der Mongolei. 280. Sphecidae (Hymenoptera). IV-V // Acta Zoologica Academiae Scientiarum Hungaricae, 18(1-2):147-232. (как Crabro cribratus
inornatus)
- Nemkov P. G. et al. 1995. Permanently. Sphecoidea. 67. Sem. Sphecidae-Burrowing wasps, pp. 368-480 [In the collection] P. A. Lehr (ed.). Determinant of insects of the Russian Far East in six volumes. Volume IV. Reticuloptera, scorpionflies, and hymenoptera. Part 1. Science, St. Petersburg, 604 p. (like Crabro cribratus)

The last mention for me personally as a participant in that project is the strangest. To be honest, I was completely sure that P. Nemkov used perfectly working tables of V. Marshakov when compiling the text of the Determinant and did not bother to check the manuscript in time. But no, it turned out that Tsuneki did too… However, this erroneous name was later corrected in the 4th part of Volume IV of the Determinant (2007, Supplement, p. 997), but still the sediment remained.
So, my advice to you is that if you are going to determine krabronin, try to use V. Marshakov's keys first.

thank you, we will have to look for the fauna of the USSR. Unfortunately, I don't have it yet. It turns out that my instance with all converging features is Crabro cribrarius ?

Of course, Crabro cribrarius.

And do not even try to search for the Fauna of the USSR. It just doesn't exist. In general, of all the Fauna issues, you can find only two devoted to stinging hymenoptera: Scoliidae by Steinberg (vol. XIII, 1962) and Halictidae-Nomioididi by Pesenko (vol. XVII, issue 1, 1983). At the same time, the first work is "weak".

In principle, I can simply send pdf copies of Marshakov's works by email.
But not only him, of course...
Just send an email to my email address so that I can understand what you're talking about.

Can I say something about this bee? Length 5-6 mm. Moscow, today.

Can Andrena rosae Panzer, 1801?

I agree, it is similar, our specimens have a brown spot on the red tergite in the middle, unfortunately this is not visible here

Thanks!!!

Let's start with the fact that Andrena rosae has two generations and bees caught in April differ in color and pubescence from July ones.
However, the first generation from European Russia may or may not have a similar brown spot. I have collected this type of material - mostly without a spot, but there are also some with a spot.

Yes, like all andren. I don't like it from photos, I always doubt it. If there are no guarantees, then I can assume:
Maybe IMG_7023 by Andrena praecox?
If IMG_6884 has red hind legs and legs, then probably Andrena clarkella In
the photo IMG_7105 which is bigger is again Andrena rosae

But I'd rather have a copy on a pin, zoom in, literature, and define. In April, not so many species of andren fly, you can sort out our ones.

Andrena rosae I have both in color, well, since it comes with a red segment of the abdomen, then I talked about it ))

And this one, what kind of bee?

I just wanted to say that they come with a brown spot on the red segment and without a brown spot

the presence/absence of a brown spot does not play a role in determining the size of the skin.

what a huge collection you have-and bees in large numbers, and wasps, and all sorts of beetles....
Edorovo!

And this one, what kind of bee?

Maybe Andrena thoracica (Fabricius, 1775)?

Maybe Andrena thoracica (Fabricius, 1775)?

Oh, and I was desperate with this group, I still have thoracica, gallica, dimidiata in question, as I understood it, you need to look at the dotted line, which turned out to be very harmful in fact.

at first, I thought maybe it was Osmia maritima, but the venation is clearly visible, which is exactly andren, although the black saturation is most likely thoracica

I have clarkella does not have this color of the back, although I think this is not the main factor, but here I think it is definitely necessary to drive by key

That's what it's all about!!!
You are the greatest optimists, if you undertake to define andren (!) by the color of the pubescence. I wouldn't dare do that...

yes, of course, it's not serious to talk about the photo before the view
itself I don't like

What is the difference between Andrena cineraria and Andrena ovina?

yes, I already wrote several times that Andren on the photo is not serious in appearance

but if it's early spring, the middle lane and good photos, then A.vaga, A. clarkella, A. rosae, A. cineraria, A. haemorrhoa can still be identified and
these species are generally determined in the field, without optics, sometimes even by flight

here thoracica or praecox is yes, the photo is hardly
a purely indication in which direction to look
and if there is no instance, there is only a photo, then the signature can be one-Andrena sp.

Andrena ovina Klug, 1810 this is a synonym for Andrena vaga Panzer, 1799
to confuse with Andrena cineraria in my opinion it is impossible
for Andrena vaga pubescence of the midspine is light gray, and Andrena cineraria with black hairs that form a baldric in the middle of the midspine

Thank you for the science.

Another bee, I hope to find out what kind of bee it is. 26.04.2011

This one seems to be Osmia. It's a little early for them to fly.

Is this also Andrena rosae?

what are you, where am I to determine. This is so, I look at my bees and give comments, although you know, if I look at the bark beetle (and they are usually no more than 3-4 mm), then I will tell you almost immediately to the genus, and knowing the breed, you can estimate the type. I think who is in the topic of bees, and the sound will determine up to subspecies

This one seems to be Osmia. It's a little early for them to fly.

Normal. I have the earliest Osmia rufa caught on
21.04.89 also on the mother-and-stepmother by the way
this is the north Flax.regions

and even in the more southern Tatarstan they should fly all the more

aha
plus it's also lucky that the pictures are from April, the set of early spring species is small
a lot of options are immediately cut
off for example Andrena haemorrhoa is difficult, but you can confuse it with Andrena fucata
but only if we are talking about June-Andrena fucata does not appear before the beginning of June
and in April only Andrena haemorrhoa

You are comparing incomparable quantities. The entire bark beetle family includes at least half as many species as the single genus Andrena. There is no need to talk about the genera of bark beetles - there are dozens of them at most... Plus a fairly narrow specialization in tree types.

well yes, well yes....

Please help me determine the nomad.
