Megachiles and anthophores.... Oddly enough, they didn't pose much of a problem for me. Although the keys were made by the same people as the Andrens. Of course, there were articles about newly discovered species, but at the time of my apprenticeship, bees were considered one of the most studied groups. If you look at it, the expansion of southern species began somewhat later... And this expansion has added confusion to the cauldron of problems. Of course, there were borderline species - those species whose range was outside the USSR... But then the articles became necessary. The fauna of Armenia, Tajikistan, Altai, and southern Azerbaijan was relatively poorly studied, and it was possible to meet both more southern bees and new forms there...
But the North Caucasus also brought no less interesting finds... So at an altitude of 1200 meters, I collected Ch. Hungarica, which created mixed colonies with other stonemasons...
But it's all romance... And the reality is this: for a normal quick determination of bees, and other insects, you need to have reference specimens, and preferably a series of 5-7 specimens. I personally went this way, and it was this method that made it possible to identify unknown species. The accuracy of the description was later confirmed. But to be honest-the description of species and subspecies has never appealed to me. And the materials were described by colleagues.

I think it is more correct to ask: And for what groups of bees can "green" even suit someone? After all, eardrums on average are studied incomparably worse than beetles - I was stunned when I looked at the year of the description of Andrena magna. But this is a healthy critter with a large range, quite long (2 generations!) In short, here you need to look at the reference material, and if possible-and standard, study systematic works, etc., etc., and "stick" to the pain in the eyes and in the brain in the tables of "green" - an unpromising occupation. Although, as a basic source, you need to start from it (which can not be said about beetles).

That's right, for push still green, and for Siberia and the DV determinant is mandatory, they are suitable like nothing else. To the point of pain in the eyes, sometimes not because there is no view in them, but because sometimes the view is quite complex, and there is little comparative material. And of course, the recently described species. In green, you come to a part of the species by comparing different species, when you come to understand the relative characteristics. Well, the definition of a subgenus is also often very important. You go out to a group of species, look at the subgenus and already have monographs and other sources.
Yes, and the source in Russian for me is still an important factor, it is unlikely that something can be found more worthy and generalized green and DV.

Well, yes, reference views are the best thing to have in your personal collection. But you need to get these standards from a "reference" specialist.
I believe you have an ease of identification from your extensive experience, which I do not have, and therefore it is better to doubt the obvious than to be sure of the seemingly unverified. Experience is a huge thing, and when this experience can be emphasized from someone, it's double luck!!!! At one time, I spent half a day sitting, starting from zero (by the way, starting from Green) with the definition of a six-toothed bark beetle (Ips sexdentatus), and now I can determine it even without seeing a beetle, but only by damage and probably even by the smell in the forest

, and now I can easily determine virtually all the species found in the forest. here in the Krasnoyarsk Territory. Now that you have a collection, the NECESSARY AND PROVEN sources of literature, you can show your employees the differences of most bark beetle species in a day by using examples.

Again I return to the old topic, I was told that A. bimaculata and A. morawitzi are reduced to synonyms. Alexey, have you heard anything about this? I have both of these types and they differ very well in appearance "in green", but I can't understand why or even if this is the case?
As for praecox and helvola, I have instances defined by a specialist, but I can't understand the main differences. In green, it seems that each type is described in different words, but the essence remains the same, it seems that you just need to wait. But for two copies, it seems to me that the person still missed, it will be necessary to check with him again. Perhaps we should look for males and look at the genitals already, so there were cases when only males saved, but while there were only females, everything was fine.

I've heard from you. According to the determinant, the species are completely different, in real life I don't have a single species.

Have you ever played Fauna Ukrainy? There are good descriptions. True, I could not distinguish these types by "Ukraine"

Thank you, Alexander!
Unfortunately, I didn't manage to shoot any other angles. Goosebumps, suspecting something was wrong, fell into the grass. And the size... mm 10-12 probably or a little more. The midge on the reverse side of the blade of grass 3-4 mm probably will be.

Unfortunately, I can't tell from this photo. You can assume. Given the size, this is most likely Formica. If we assume that this is the case, then it is a subgenus of Serviformica. In this subgenus, there are several species with black females, but the most likely size and shape is Formica fusca.
Black Camponotus females that you can find here are usually larger (15-18 mm). Only Camponotus fallax is suitable in size from this genus, but it has other forms.
Most likely is Formica fusca (I think somewhere 60-70%), but I can't determine exactly. Увы.
