Identification of Hymenoptera (wasps, bees, ants)

But someone will say something about this animal?
Volgograd region, Mikhailovsky district, floodplain of the Medveditsa River 6 km below the town of Mikhailovka, on a drying oak trunk. 14.05.2009.

orussida Orussidae

I crawled in the burning pine forest. Under the bark I found such passages and larvae. And then something came out from under the bark, smeared with ash, and flew away. I managed to understand that it was a webbing. Can you tell me who this insect belonged to?

I had a chance to identify a male from Adler (without genitalia, these species are difficult to understand). Definitely S. deforme. When compared with the eastern and Nizhny Novgorod copies, there is no difference.
By the way, Christian Schmid-Egger, who once paid attention to the distribution of S. curvatum in Europe, believes that in some of the cases described, S. deforme appears under this name. Just local faunalists "identified" their wasps on the fly.

"local faunalists defining their wasps on the fly" is probably a stone in my garden I agree with the respected AVA-it's difficult to understand without genitals. Even more so from the photo. However, let me assume that Dr. Christian Schmid-Egger did not work with material from the area where local faunalists determine their wasps on the fly . But Mr. Mokrousov caught curvatum there this year, so maybe these "local faunalists"are not so bad?

There is a definition conflict
Initially, it was assumed that this is Ammophila pubescens, but then it was suggested that it is not Ammophila at all. and Prionyx kirbii. But what is it?

Earlier, one of the larvae I captured was identified as Birch Cimbex femoratus (Linnaeus, 1758). Looking through the footage taken last summer, I seem to have identified the actual imago of this sawfly. Am I right? Is that him? In the literature, it is reported that the lower part of the abdomen in females is yellow or bardic, in males with yellow spots and a bardic middle. There is also a sense of stripes. Taken in Chelyabinsk. July 2009

As I understand it, it is difficult to determine andren from males. Here I want to show you one of them (photo 1.). It was caught on the flowers of legumes, in the forest. Rep.Khakassia.
Size 13 mm, wingspan 23 mm. Here are some signs of this bee.
- black trim plate.
- body without metallic luster.
- pubescence of the body in light hairs, the abdomen is pubescent with traces of thin bandages of long light hairs. Photo 2
- the median field of the intermediate segment is roughly wrinkled and stands out sharply.photo 3
- the head of the middle is pubescent with light hairs at the antennal pits in darker hairs (smoky brown). photo 4
-the tergites of the abdomen are rough-punctured photo 5
- all the segments of the legs the base of the legs is red.Photo 6
On the green I go to A. tibialis Kirby., but the color of the top and tergites is confusing

Of the three photos, the sawfly is only on the last one, the first two are ichneumonid riders, the first one reminds me of the male Alomya sp.
In true sawflies (Tenthredinidae), in addition to the characteristic habit, there are much fewer segments in the flagellum of the antennae.

Compared with its specific males A. tibialis-very similar. The only difference is that my specimens do not have whitish, but yellow-brownish pubescence. You probably have the second generation. The second generation has a more shiny midrib (as in your photo) and a rarer and lighter pubescence. In the "Fauna of Ukraine" for the second generation, it is just the whitish pubescence of the midrib and the rarer and lighter pubescence of the abdominal tergites. I would vote for tibialis.
Thank you for the quality photos. You can also use these criteria to determine the location.
Oh, if only everyone would remove instances that require definition like this...

Thank you so much. Well, I used to understand the signs myself, and besides, while the technique allows it. If there was more time, I would regularly throw you a thread from andren ...I have a lot of this stuff here and most of them are not defined at all

Well, there will be time-throw it up. It's a pity, there is no guarantee that I will determine. But I will try.

A bee from the Nomada genus. The wingspan is 15 mm. The body length is 10 mm.
3 media cubicles. Photo 1,2.


The upper lip is red. Photo 3.

The head and entire body are covered with sparse hairs. The wing caps are red. Srednespinka with 4 red stripes, densely dotted. Shield in the center with a large red spot. Two red spots on the intermediate segment. The lower legs are red with darkened thighs at the base.photo 4.

The base of the first tergite is black, red beyond the middle. Photo 5

2nd tergite with lateral yellow spots.
3rd - the base is red, the top is darkened.
4-th with yellow rather large converged spots.
5th tergite with a large yellow spot.
As a variant of N. guttulata or N. zonata
There in the variants of abdominal colors, the devil will break your leg....
On the lower legs of the hind legs, it is difficult to understand how many spines, like 4 dark, not long. Photo 8.

Very interesting (one of my favorites), but also very difficult to define the genus. I would like to have some up-to-date work on Palearctic nomads. While I do not have a good modern literature on the genus, I will have serious doubts when determining the representatives of this genus.
But in this case, I think I can define this species - it is too peculiar. You caught him in the spring, didn't you?" I think that this is Nomada bifida Thomson, 1872 ( according to the "green" identifier) - a parasite in Andrena haemorrhoa
If I am not mistaken, now this species is more correctly called Nomada ruficornis (Linnaeus, 1758). However, in the synonymy of the genus Nomada, the devil himself will break his leg. In general, Nomada bifida by the "green" determinant. In the Leningrad region, the view is normal.

According to Nomada bifida, I looked at the photo, that there are bandages on tergites that are too developed, although I think these are color variations. I'll check the caller ID tomorrow.
Another nomad, as it seems to me, is Nomada sexfasciata. Photo 1

13 mm long, 20 mm wingspan.
The abdomen is black with a white pattern, without red. Photo 3.

Shield with 2 light spots. Photo 2.

The head and chest are densely pubescent with rusty yellow hairs. Photo 5

The cheeks are quite well developed. The face is drawn in a straight line (when viewed from the side). Photo 8.

The frontal keel is normal (sort of). Photo 4.

On the lower legs of the hind legs (at the top) like a spike, but it's hard to understand what it is. Photo 7

Andrena. Male. 23 mm. Wingspan, 12 mm. - size. photo 1.

The trim is black. On 3-4 tergites bandages of white long hairs (not thick).
On the sides of the 2nd tergite there are spots of sparse hairs, the top of the 2nd tergite is reddish. Photo 2

The median field of the intermediate segment is gently wrinkled. Photo 3

The 2nd syllable of the flagellum of the antennae is short, shorter than the 3rd. photo 5.

Cheeks like at the base of the mandibles without a tooth (although this is not certain). Photo 6.

Tergites are densely dotted and shiny.
The face is covered with smoky hairs, and the trim has black-brown hairs.
The back is pubescent with thick light hairs in the center with an admixture of dark hairs. Photo 4.

On 1-2 m tergites in the center in long, but not dense hairs, as well as in short dark pressed hairs.
Paws are dark, with light hairs.
As I think this is Andrena rosae Pz., I would like to hear proffi

Cimbex is some kind of femorata?(up to the form I find it difficult..) .

According to Nomada bifida, I looked at the photo, that there are bandages on tergites that are too developed, although I think these are color variations.

Yes, in the photo from some German website, there is more yellow on the abdomen than on my copies. Most of my specimens have almost no yellow spots on the 3rd tergite. It is not particularly successful to determine nomads by the color of the abdomen.

I think you're right.

First sawfly Arge sp. (Argidae) - (something from A. nigripes Retz. - A. pullata Zadd.)
The second is Cimbex femorata L. (Cimbicidae)
The third one, Trichiosoma sp. (Cimbicidae), differs from Cimbex by a large upper lip, the presence of teeth on the middle and rear thighs, the absence of a membranous notch of the first abdominal tergite, and a more developed pubescence of the body.
The fourth one is from Tenthredinidae

KingSnake. OS images on the cell (message from 26.08.2009) - not Polistes nimpha (Christ, 1799), but Polistes biglumis (Linnaeus, 1758). Nimpha coloration with a more pronounced yellow color. More specific features are the abdomen with black rings, without light markings on the band from the second tergite (in nimpha, always with markings). The last abdominal ring is almost completely black, which is characteristic of the species biglumis. Thorax with very pale light markings (also characteristic of biglumis, in nimpha with distinct yellow spots). The cheeks are not very clearly visible, but they seem to be black in the lower part, without stripes - only in biglumis. Also Justus (message from 26.08.2009, image of a nest from Khovatia) - similar to Polistes dominulus (Christ, 1799), but not sure, since similar polistes species are common in Central and Southern Europe.

what about the last andrena? By the way, what about the definition of the genus Eucera ? males

No time at all. I can't get to the boxes of andren. I'll tell you something one of these days.
Well, if you take into account the quality of your photos, then you can also try Eucera...Only on any occasion not earlier than Thursday or Friday.

dear alex 2611 I will be glad to hear your comments. I will also give you a few tasks for the Nomada family, which you love. Friday, so Friday

I would like to say a few more words about Nomada bifida, and I've looked at it carefully again. It seems to be suitable for a number of reasons.But something confused me.
1. it is indicated that the mandibles are two-pronged. I don't think I found any teeth in mine, but the mandibles are quite pointed. Maybe it's just that the teeth can't be seen from the front like this?

2. what's on the 5th sternum of the recess? I didn't find anything like that

3. mine has rather weak pubescence of the body, this one is characterized by rather thick pubescence of the hair.

In addition to the male Andrena tibialis, I would like to show a female, which I think is a female of the same species. Was caught on 14.07.09 (2nd generation). It is 13 mm long and has a wingspan of 23 mm. Photo 1.

The breast is covered with light red hairs. Tergites are pubescent with rather short pressed sparse light hairs (on the 1st tergite they are thicker and raised). Photo 2.

Anal fringe of dark brown hairs. Photo 3.

On the tops of the broken bandages of sparse hairs. The lower legs of the hind legs are covered with golden hairs. Photo 4.

Tergite punctuation is clear, but not very frequent. The pubescence of the head consists entirely of light hairs, only on the back of the head, the color is red. Photo 5.

The sides of the chest are covered with light grayish hairs. The midrib is rather shiny, sharply dotted in the middle.

and so I also wanted to show a photo of one nomad, in green it turned out to be a rare species, as indicated there. N. roberjeotiana Pz.

The first photo is a male Hylaeus. I'll try to see if I can get to the end of it.

The second photo is not a Macropis case? It seems similar.

At the expense of the teeth in the photo, it is difficult for me to see. Look carefully at your copy under magnification. My specimens clearly show a two-pronged vertex.
In general, it would be good to spread out stinging webs with their mandibles spread apart. But it doesn't always work out for me - sometimes my head comes off when I make an effort. For rare species, this is a shame.

Indentation on the fifth stubble at the very top, almost at the sting. A small indentation. It seems to be visible in the photo.
