Breeding of osmium bees. Osmia rufa, cornuta, hives

You are lucky, and not only with bees.

It's strange for me to read this about megahill. I don't remember about Donetsk anymore, I was there a long time ago. But in the Vinitsa or Khmelnitsky regions, as far as I have seen, there are certainly at least a dozen species.

P.S. About luck - we say that someone who is lucky is lucky. And it's not personal.

I won't say anything about megahilus, they all look the same to me, but I don't remember meeting osmium, except for cornuta and bicornis. Donetsk region is not only Donetsk, it is also the most beautiful nature reserves. There's a lot of stuff out there. And many species of insects that we have listed, entomologists see once in a hundred years.

Speaking of megachiles, the bee that I caught a glimpse of yesterday and thought was Osmia bicornis has returned today... with a pollen-filled brush under the belly. So now I have a megahila nest on my balcony, and even in a transparent tube! Never before in my memory has such a thing happened. But here's how lazily it vents compared to osmia: no more than one arrival and departure per hour. And I haven't seen the leaves yet. Or are there some of them that can do without leaves?

I report on the anthophores: no one came to the two burrows dug yesterday, pollen was carried all day at two more, and another bee started digging a new hole. This is only in the part of the box that I can see, on the other side there were at least two more individuals nesting. Searching females also continue to visit. Osmia also come: one cornuta flew all the way into the apartment through the open door, then safely flew out on its own, and bicornis carefully examined me for the presence of suitable cavities. But here to the hive Fabre, and, in general, to the place where it hangs - not the slightest interest, even strange. Well, never mind, the Eumenins will get more reeds. I made two more small beehives based on the new concept and put them in other places. Now the entire balcony is blocked off, not a single searching bee will fly past the reeds without seeing them.

A bumblebee flew into the stairwell, apparently a long time ago, as it was sitting on the floor and did not fly.
I took her home, made a nest in a box, a corridor with honey, but she can't sit, ate, warmed up and that's it, wants to go outside https://www.youtube.com/watch?v=VnZjrx-9Q3g
I don't let her go outside - she doesn't fly well. I want to start making a nest in a box.
It happens that he runs away and flies a little in the hut. https://www.youtube.com/watch?v=q3GhU8jcfuw

Pollen will need fresh so that it gets a nest in a box.

can you give me a link to read it?

When it is ready, I will give it to you, but it will be purely faunal work, without nesting.

osmium, except for cornuta and bicornis, I do not recall meeting.

You probably just didn't recognize osmium in them. Not all osmias are red and hairy, there are gray, black, blue, and even green ones, and most of them are smaller.

Speaking of megachiles, the bee that I caught a glimpse of yesterday and thought was Osmia bicornis has returned today... with a pollen-filled brush under the belly. So now I have a megahila nest on my balcony, and even in a transparent tube!

What makes you think that?" All our megachilids have a brush under their bellies (except for parasitic ones, of course). Megachiles even here are still in the state of pre-pupae, none have yet flown out (except for M. parietina, they spend the second year wintering in the form of colored pupae, so they fly out early, but they are not known to live in tubes). These are not osmia, which almost all overwinter in the state of imago in cocoons (except for the subgenus Hoplosmia and maybe some other small groups).

Well, I definitely didn't see any blue and green bees. There is only one black one, but that one carries pollen in its leg. It is rarely found in the crane, only in the steppe. Here in the topic about cameras, I posted a lot of pictures of different bees, are there any osmias among them, except for cornuts and bicornis?

I looked at photos of some types of osmium, yes, indeed they have a clear brush sometimes, like megahills. So, probably, it's still some kind of osmium, since it doesn't wear leaves, but it's very, very lazy. But definitely not cornuta, and very unlikely bicornis. It is long, the abdomen on top is dark brown shiny, slightly pubescent, the brush is a contrasting bright yellow color (although maybe only from pollen so). In general, the spitting image of a megahile. I didn't manage to take a picture, it crashes and crashes very quickly, and this rarely happens.

  
We have very few megahils (compared to osmia), and they are mostly found far from city blocks.

In the Donetsk Botanical Garden, I caught not so few megahills. Another thing is that they do not fly in such "crowds" as osmii
, but if you sit on any urban wasteland in the summer near the thickets of chyna, alfalfa or peas, you can meet a lot of megahills. And other species on thistle flowers

And we have 25 megachilid species and 23 osmium species (I just started doing an article on megachilids of the Crimea, these are the numbers that are obtained).

Great! I have only
Megachile bombycina (Radoszkowski, 1874)from the Crimea
Megachile versicolor Smith, 1844
Megachile ericetorum Lepeletier, 1841
Megachile pilicrus Morawitz, 1877
Megachile centuncularis (Linnaeus,1758)
Megachile pilidens Alfken, 1924
Megachile apicalis Spinola, 1808
Megachile leachella Curtis, 1828
Megachile dorsalis Perez, 1879
Megachile melanopyga Costa, 1863
Ну и два вида халикодом. They are also now included in this genus.
And a couple of unfamiliar species from last year's collections that have not yet been fully disassembled

Snake Osmia caerulescens (Linnaeus, 1758) in the Donetsk region is a banal of banals. In May, I caught quite a lot. It is metallic shiny and smaller in size.
Yes, and other types you have quite met

Your list is very strange. I have several thousand copies of the largest collections in the Crimea (Simferopol, Kiev, Moscow State University, ZIN), not a single Megachile bombycina from the Crimea came across. Did you catch it yourself?

And with Megachile dorsalis, what did you have in mind? This name describes the female M. leachella and the male M. burdigalensis, which is distributed to the west.

Here in the topic about cameras, I posted a lot of pictures of different bees, are there any osmias among them, except for cornuts and bicornis?

There is absolutely no desire to search somewhere for a topic about cameras.
It's better to see what they are like here- http://www2.pms-lj.si/andrej/apoidea.htm

And my osmium flies for food, but so far there seems to be only one, after all, we probably don't have enough such osmium, they need more forest.
I look, osmium looking very simple-a lot, you now need to look closely at each bee.)
Of course, the work was done incredible on that site, but alas, here is a clear example of how excessive sharping spoils photos, destroys all the details..

For example, a photo of ceratina from there



and my ceratina-the size is the same, my photo is blurry, but you can see much more details. The same effect is approximately from the flash, so probably with the flash there are mostly photos and fotkali.

Megachile bombycina caught it myself. The only instance. But if that's the case , I'll double-check it again.

Megachile dorsalis was defined by Banaszak and Romasenko 2001.
They have this view.

  
I can assure you that all the banals found in my area of the city in March-early April of this year are photographed

Ezoks, he is such, he has, like all ixperts, "all or nothing" Of All the bees in the garden perefotkal, the tooth gives )))

I only re-photographed all the "banals", non-channels, probably not all of them. Also, regardless of the "banality" of bumblebees, I didn't take many photos - they don't fit into the frame with my nozzle. But I did catch one very unusual one for our places. After all, the willow is a force, and once it bloomed, it became much more difficult to engage in bee photo hunting.

I don't have much luck with the nesting of osmias this year. Or rather, the osmias have no luck nesting on my balcony. Here is one bicornis, looking for a place to nest instead of my beautiful Fabra hives, climbed into a certain recess in some plastic bedovine, carefully stored on the balcony from time immemorial, and could not get out again. So I went out on the balcony and heard someone buzzing. At first I thought it was the anthophores working in the box, but I was confused by the tone and length of the buzzing. I followed the sound and saw her. I took a picture, then stuck the brush in the hole and took it out. I took off from the brush without any problems, but my balcony will probably now fly around the tenth road.

It turns out that repairs should be made specifically for them, so that such situations do not recur))

Some of the animals from yesterday's catch
Eucera? with three qubital cells..
A very strange, very timid bee, it doesn't seem to be an andrena - two cubital cells, but it doesn't look like an osmium either, its color is more like an andrena.
Also a huge bee, 2cm in length, it looks like an andrena, I definitely have not seen this before!

1. Eucera sp. male.
2, 3. 6. Eucera caspica female.
4, 5. Andrena sp. (it resembles the male A. magna).
7. Anthophora plumipes female.

This is necessary! If this andrena resembles a male magna, which, according to the description in the CC, is smaller, then what is the female?
In any case, interenso that in our places there are such.

And again these huge photos of Ezoks (((
Do they really not interfere with anyone but me to read what is written? I have horizontal scrolling everywhere on opera and Firefox because of these photos. Explain to Ezox that even 1000 on the long side for soap photos is overkill-like a wall of peas..

We also have such interesting bees with a conical backside since the day before yesterday. Two days in a row in the same place, I probably meet one copy. All the time he turns around a small snag, occasionally distracting himself to drink the nectar of several dandelions growing nearby, which have already completely sat. Mating behavior of the male?

Melecta, a parasite of your anthophora. Waiting for the female.

Here is another from yesterday's photos-probably also a male Eucera, but there are two cubital cells, probably a male Eucera caspica.
Well, the usual andrena is now in the steppe

Melecta, a parasite of your anthophora.

Mention the devil... Today I flew straight to the anthophorium box. But something she didn't like, probably the nests are not at the right stage yet, she flew away, almost colliding with her forehead with the arriving anthophora.




And before the type of it can not be determined in any way?

Melekta returned and crawled into antaphora's hole. But she was "lucky" to choose exactly the nest in which the owner was. As a result, melekta, pursued by antofora, flew out like a bullet, and has not yet returned.

Both osmias (cornuta and bicornis), which have settled in two small hives of Fabra, are slowly getting enough food. The strange bee in the transparent tube is no longer there, a piece of pollen bread is visible through the hole and an earthen (seemingly) plug is behind it. But how slowly this bee works! After two hours of observation, she never arrived. Anthophores that have already dug their burrows also work slowly, arriving with cargo once or twice an hour. I wonder how they transport pollen. They don't have a brush, and they don't have much of a leg. Such portions and at such a pace, to feed such hefty larvae, probably need to fly for several months. But this is not the case. Maybe they also carry pollen in the goiter? At the same time, the anaphores who settled later continue construction work, making frequent absences. obviously, for "refueling". New female seekers are constantly arriving.

I went to the fields and saw very interesting bees: the body is supposed to be from Andrena, thin, with a red chest and a gray belly, and the whiskers are from eucera. Unfortunately, I only managed to take a full-face photo:





We sat mostly on nonea, but one bee also visited dandelion. But on the blackthorn and other rosaceae there are none at all, there is an abundance of colletes or something similar (there are no photos).

P.S. I looked at other people's photos, this long-whiskered bee is still Eucera, longicornis or something close. I used to think they were all stocky, like cubs. And the females of the same longicornis are the spitting image of andrena. Well, how can you figure it out without putting it on a pin? Ants-and those will be easier, there at least the genus is almost always immediately visible. And with bees try (under)the family guess!

This is who is used to what. I don't know ants, and I don't see anything in them, but I see bees all at once. But I will say that males of eucerae are determined only by their genitals, and melects are not a well-developed group at all, nothing is determined there (although we have two or three species there, hardly more). I can't say about the usual andrena, I hardly know them.

And how do anthophores with such a lousy leg manage to provide their nests, do you know?

Their bread is very thin, mostly consisting of nectar.

Oh, so you can get honey from their burrows? But where does the squirrel larva get its eggs from? It seems that in order to grow such a hefty and energetic bee, you need a lot of protein.

Here is sfotkal antofora with obnozhkoy:



Very weak, especially considering that she does no more than two walks per hour, and more often - one. During this time, osmium, even cornea, even bicornis, manages to bring a full brush of pollen five or six times, if not more. The riddle is straight.

Footage from the video recording of the departure of Osmia bikornis:



Interestingly, it flies off almost backwards (obviously, in order to once again refresh the memory of the return journey), you can't see it by eye.

I didn't say there's no pollen or protein in there. Just a thin loaf of bread, more nectar. In osmias, it is crumbly, more pollen. Protein is enough for both.

So one of the other times does not follow? There's a shortage of protein in the nectar. So less pollen = less protein, right?

No, it should not be, since anthophore larvae do not develop on osmium stocks. Pollen as a source of protein is quite enough for them. And the carbohydrates of nectar are perfectly processed into lipids of the fat body. And this is already a source of energy for the imago. That's why the anthophores are so shifty that you can't catch them in the lens...

And where does the nitrogen come from? Not to mention other elements besides carbon oxygen and hydrogen. Pollen is obviously a good source (for those who know how to digest it), but if anthophora loaves contain very little of it, and they consist mainly of nectar, as Carcharot claims, then it turns out to be a paradox. The energy of carbohydrates or fats is, of course, wonderful, but you also need to have somewhere to stay.

He didn't say that it wasn't enough. He said that it is relatively smaller than that of osmium.
