male, whose can it be? regularly come across

All photos are fresh, Ciscaucasia

1. Similar to Andrena flavipes
2.Osmia bicolor.
3. Male Osmia sp.

In No. 3, I suspect Osmia rufohirta, as they are present side by side with Osmia bicolor, and there are enough shells here. Isn't that him?

Melekta is asleep. I don't really know.

I suspect Sphecodes fuscipennis, since I was hanging around the colony of Colletes cunicularius. Similar?

Thank you, I asked to join the profile group on Facebook and they confirmed my version. It is also included in the annotated lists for Crimea

In Colletes cunicularius, Sphecodes albilabris Fabricius, 1793 usually rotates in a colony. Isn't this their main parasite?

What's the band?

Dominant or gallic? Ciscaucasia

  https://www.facebook.com/groups/242379842562550/ but on inaturalist, people don't want to define up to a view. Although there are only 2 types of melect in the Crimea and they visually differ well

Saratov, Kumysnaya Polyana Forest Park, April.
Vespula vulgaris?

I do not give up trying to determine this osmium. Size: female about 12 mm, male up to 10 mm. Similar. The color is radically black (anthracite). The upper part of the body is covered with pale yellowish hairs, which give the upper part of the abdomen a bronze hue. Black hairs break out on the platypus, the bottom of the abdomen is all black. They often carry passengers(by the way, do you know anything about them?). Active since the end of March. Females have appeared recently and are quite common. Foothills of the North-west Cc.

It will not be possible to determine, neither the shape of the horns nor the genitals of the male are visible. One can only assume that it is O. bicornis, but it may also be an obliterated O. cornuta, and O. cerinthidis is unlikely on Rosaceae. The passengers may be mites from the genus Chaetodactylus, which feed on pollen, sometimes destroying entire nests.
