Identification of Hymenoptera (wasps, bees, ants)

this is my Colletes cunicularius collected on a willow tree in the south of the Krasnoyarsk Territory. It is certainly not so beautiful and elegant, but the last sternite leaves no chance of being confused with andras or with other species in our country.

Specimens collected from various locations are closest to Evylaeus in the morio group

Head and mesosome with a faint metallic green tinge. Abdomen without metallic luster.
Midrib is densely dotted, rather shiny between the dots. Mid-spine in front of the center with a central groove, at the top with a small depression. The sides of the chest are quite matte, with almost invisible dots. Back vertical part of the gap.the base has rounded edges, while the bottom edges are more angular. The horizontal part in the tangled longitudinal wrinkles
of the 1st tergite is quite thick and distinctly dotted. Tergite tops with bandages, the first one is interrupted.

If it is Evylaeus, then why is it green and with vertex bandages? Maybe it's Seladonia?

I have a series of E. morio, signed Pesenko just like that-most are clearly two-color-chest-abdomen, and both sexes are very bright and shiny green. I can't say anything about the photos above, except about the mount-since the dotted line is important for halictids, I prefer to mount it differently, although not for this reason (it's a pity to break through, and it can be useful for photos, and even more so for flies - if the bristles matter, choke, crumple, or leak out "juice" can spoil the color of pollination), - single stick directly to the pin for the side of the breast-tegula, and the series-so as not to waste pins - on plastic triangles (they are elastic - do not hang out) for the rear basins-the base of the abdomen - T. Levchenko when he determined the material,approved, said that the necessary signs are visible. PVA glue is easily soaked with a couple of drops of acetone, if necessary. And pins also rust over time, where they come into contact with"meat". Well, I immediately pick out the genitals of males.

To avoid clogging up the report forum ( http://molbiol.ru/forums/index.php?showtop...0&#entry1551563 ), I'll post photos for the definition here. They were made on the advice of vafdog, it seems, came out more or less high-quality. What can you tell from them (if possible to the floor)? Thank you in advance!

Female Bombus terrestris?

Vasily L., yes, I look, the new cameras don't have very good photos, I had an Olympus S-150, I bought it in 2000, 2 mp, no zoom at all, no macro mode , I had to take pictures through the lens, so the macro was many times better there.. And the optics were better - all the glass was illuminated, albeit small..

As for the sex, the bumblebee is definitely a female, and also a uterus, now there are no others, but for xylocopa, the keys were posted in the topic of reports, IMHO valga is, it is clear that the segment is short on the antennae.

Thanks! Yes, indeed, before the cameras were better, although without bells and whistles... Or have I not yet learned how to take pictures properly?
A bumblebee IMHO-exactly from the group Bombus terrestris, but still-who exactly? Isn't it Bombus terrestris itself? Or is there nothing more specific to say from such photos?
The keys were hung out, but they also asked to post photos. I also turned the copy over and over. in the hands - still Xylocopa valga.

Well, if you set the macro mode exactly, and the lighting is normal, then don't be able to do it, but it should come out, especially since small matrices give a very large depth of field, and autofocus works perfectly for this, you need to try, your camera shows a macro with 3 cm.

Thank you for your advice! I'll try again. As they say, everything will come with experience!

perhaps "breaking through" for another reason is not correct, but in order to see the dotted back does not particularly interfere, especially the individuals are quite large. Small ones are usually glued to the dies, but I try from different sides, so that the signs can be considered without dismantling.

If it is Evylaeus, then why is it green and with vertex bandages? Maybe it's Seladonia?

On the "green" I come out closest to this view, for it and species close to the theses are characterized by such bandages. According to Pesenko, as I understand it, this species is assigned to the genus Evylaeus (p. 797 )

1. something like Anoplius viaticus
2. Nomada sp.(bee)

Alexey, have you compared E. morio with your own?
Most of the questions are related to the clear punctuation of the first tergite.

Eugene, festive kebabs-cognacs tortured
Yes, and the fishing season has already begun, I postponed the definition until September.
Tomorrow I'll try to get the box of halicts back.

I don't define it myself. Sometimes specialists help. But again, only by photo.

Is there anything to say about this ant?

Female of the genus and subgenus Formica. And before the appearance-you need to consider the hairs. No way without it.

Orussus abietinus Scopoli (Orussidae)

Help me identify the beast. Very large bee / wasp. I think the bee is a carpenter, but I'm not sure. Caught today. Angarsk, Irkutsk region. Temperament is calm, does not bite.

It's not a bee/wasp. This is a sawfly from the family Cimbicidae, most likely Trichiosoma villosum

Well, just like that, right up to the view? And why, exactly, do you need it? You are not even an amateur collector, otherwise you would have bothered to tell us at least the place and time of collecting. But the quality of your images in most cases does not allow you to determine something reliably.
By the way, the top two are flies.

Rhyssa persuasoria (Linnaeus, 1758)

If it is Evylaeus, then why is it green and with vertex bandages? Maybe it's Seladonia?

The more I dealt with a group of similar species, the more I was inclined to believe that Alexander was right. This is really most likely Seladonia, something from the subgenus Pachyceble, according to Pesenko. About 5 species are similar to each other, but differ in the structure of the metoapostnotum, dotted mesoscutum. In the same Evylaeus, the venation is completely different.
From all this group, so far it has been possible to distinguish specimens from the same Ze-Qing Niu according to the description of similar S. leucahenea

Pamphilius?

It is strange that experts do not write-this is Osmia, I think, and you can call it up to the form. Germany (if you mean Germany) - almost 360 thousand km2, it would not hurt to specify the collection point.

The fact that this is Osmia is obvious. But the rest is unclear.
For example, what are these blurry "horns" on the face? It may be O. cornuta, but the picture is not very revealing. In my opinion, very overexposed.

Take a closer look at your images and those from the specified site. In Osmia bicornis, the chest is covered with thick red (!) hairs, and in your specimen - dark brown. This is not the view.
