Identification of Hymenoptera (wasps, bees, ants)

 

I would like to check out a few more bees, I consider them to be andras for myself - probably mostly so. This is all the Novgorod region. If they are recognizable in the images, please name them.

These I suspect to be Andrena clarkella. Both pictures are taken in May, the bees are different, but similar. The first has a light pubescence of the body, the second has a dark one.

Novgorod region, end of April.

This specimen resembles the male Andrena haemorrhoa.
And the last photo is of a female of this species.
But in general, it would certainly be good to look at the propodeum. Then there would be no doubt

Thank you very much, and I'll try to take your advice into account in the future.
Here's another similar male (isn't it a male?) "they appeared on the same Andren colony back in April, as soon as the snow cleared. Is there anything you can say about him?

It's a female
Similar to Andrena praecox

Wah, shame on me!
Thanks!

Macropis ?europaea (Melittidae), it seems. But I'm not an expert.

Thank you.
The bees have been lying in the indefinite for a long time.
Novgorod region, July. I met them once on a rocky dirt track, but I couldn't find them anymore. Osmias have a similar venation, but there should be no baskets. Judging by the wings, these are some kind of halikts, but I'm afraid to get my finger in the sky.

Panurgus calcaratus
We have in Flax.it's pretty common. Most often caught in the second half of the summer on flowers of compound yellow color. Less often on the paws. Yellow color is definitely preferred.

And immediately the Novgorod region June.

And then not to return to the topic.
It's a honey bee, isn't it?

What kind of corostavnik is this? More like a groundhog.

I forgot to come in, I was the one who was apologizing for not paying attention.

In this case, you only need the right eye. Well, practice in nature.

Now it's simple - I identified it and checked it from the photo on the network. And I then identified most of our plants in the 70s and 80s only by the determinants, there were no images.
So you start to doubt sometimes

I apologize for the off-topic question. But it's hard to reach the administrator.
In recent days, I haven't always (or rather, very rarely) been able to attach photos to my email. I click the "attach file" button - the selection window is reset to zero, but nothing is attached to the email. No traffic restrictions seem to have been announced. Right now, for example, I can't attach anything to an email, not even the files that were previously attached. Changing the browser did nothing. Is the forum engine slowing down, or is there a problem with my computer? Is this a problem only for me?

I had a problem with this for a few days too. I managed to push one file through this morning.

 
And here's the white-tailed bird. The flowers are completely different.
