Wasp nests

Well, the usual size, and their uterus seems to be almost the same, I've never caught a uterus, though. And the males, too. Only workers, I have them at home. The size there is about the same, about 2.7 cm Hornet for us-a rarity.

Another thing that makes hornets unique is that they are supposedly foraging even at night. For polistov and German I can say for sure-at night I never saw that they flew out/flew into the nest.

Other than foraging, I can't explain the constant arrivals of hornets into the world, sometimes they greatly interfere with catching butterflies. By the way, on the same evening there were also workers, but only about ten of them at most. The workers are the same size or smaller, but the female is slightly larger, but photo no.

Interesting. But in any case, something is wrong with the socket. Perhaps the uterus laid eggs before death (as a result, large larvae), and the males-eto from workers.

There is nothing unusual about the presence of males.
Dolichovespula saxonica has a short life cycle, and the active phase of the nest existence of this species ends by the end of July-beginning of August.

I agree. I thought at the time that he was talking about hornets, and in the end I got it wrong.

Hierophis, you should do well with germanic, as they are quite tenacious.I watched on the BBC how it seems that two female germanics and were accidentally brought to Australia...they have become perennial))Once again, good luck to you)you will succeed)And next year I will try to make multi-year polysters.

By the way, I sent you an invitation to be a friend in VK, name:Andrey Savin

See your personal page.

 
Do you have a row of" male, worker wasp, queen " hornets? If there is, then take a picture and post it. I once searched for data on this issue - the size of males, queens, cell diameters - I didn't find anything.

Collector, thank you, I have already recognized that hornets do have a certain polymorphism, although the German ones are obviously more pronounced, whereas polists practically do not have it. So by this criterion, hornets are somewhere between these two categories )

vespa crabro, and I do not think that it will work, or rather most likely it will not work. Because already in the nest, the population is clearly declining, foraging is almost not observed, T during the day is ok +5C, at night the truth is the same. And glanvoe, thermoregulation ka kranee I already something do not observe, probably the number of wasps in the nest is very small. Another bad thing is that you can't see inside what's going on there.

In nature, I think we have already completed the nests cycle, this weekend I will dig up.

if you keep it in terr.(and it can and is possible) then should become multiyear

and what if they are better insulated?

So, they still probably need some kind of activity, they are not adapted to spend the winter like bees.

Here I was given such a link here, I think that it should be posted here!
http://www.venomlist.com/forums/index.php?...acket-journal3/

the idea of course intersenaya, though quite destructive for the nest, but it turns out something!
Here in this form, it is quite possible to get a fairly long existence, but still hang the nest right in the room-it would be more fun))))

interesting..

Yeah, I gave the link)

And note Hierophis, this chela has less terr than us))

In general, I went today to dig a nest of Germanic birds in the ground. On the street it was OK +3C, so I went without any ammunition, only with a shovel and a bag)
I got to the place, cleared the entrance, in general, intuitively chose the place where to start digging, dug three times on the almost full bayonet of the shovel, and unearthed the nest.
The ground was very good for digging, not dry or wet - one dig and a whole block is dug out.
The nest was located at a distance of about 20 cm from the entrance and at a depth of about 30 cm from the ground surface. In the nest with a diameter of about 25 cm, there were 7 tiers of honeycombs, two uterine, one full-sized and one rudimentary, the upper honeycomb of working wasps was almost completely thinned, obviously for the construction of uterine honeycombs. The thickness of the paper shell was about 2 cm.
The nest strip was almost spherical, just over 30 cm in diameter.
In the nest there were no larvae or remaining frozen wasps in the cells, the development of the nest ended perfectly!
There were very few dead worker wasps in the nest, only about a dozen, I didn't notice any males, but there were two live queens, one with a wing defect!
I also found a few nest-specific larvae of some sort of beetle.

There are no photos yet, as the batteries are dead everywhere

Thus, it can be concluded that the development of nests was completed perfectly and with maximum hatching of males and females, without the dominance of parasites and half-decomposition of the nest, as it happens in years with wet autumn.



I also had to sort out the nest that was on my balcony.
At first, I decided to just take a look at how things were going, but after what I saw, I decided to sort it out.
The fact is that it was full of larvae and corked wasps in the honeycombs, and some of them were already beginning to darken and rot, although a lot of the larvae were alive. The nest contained 4 tiers of working honeycombs with a maximum diameter of about 20 cm and a rudimentary uterine honeycomb. The thickness of the paper layer was approx. 3cm.
The two upper tiers were almost empty, but the two lower tiers of the working type were almost completely filled with maggots and clogged cells! Thus, it is clear that development in this nest did not stop as early as in the nest on the street in the ground, moreover, among the young wasps there were also working wasps! This suggests that the uterus laid fertilized eggs until the last one.
However, the population of the nest was already quite small, there were approx. There were 20 worker wasps and about the same number of males, and several more dead males and worker wasps were on the bottom and between the combs. I didn't find any wombs, including the old one.

Thus, it turns out that in conditions with the presence of frost protection and the presence of heating, the nest does not stop its development until the very last moment. However, the time still comes and the worker wasps begin to die out, the larvae and sealed wasps also freeze and begin to die, a putrid smell appears in the nest and the wasps and larvae are still alive in aseptic conditions. No wintering of the nest with its old queen and wasps is out of the question in this case!
Only continuous operation of the nest in conditions of temperatures not decreasing below +15C can possibly prolong its existence, by analogy with tropical perennial nests of German wasps.

Is it already winter for everyone?)

We don't have it yet! Today ok +6C and dodge like a bucket!! And yesterday it rained, and the day before yesterday, probably soon the boat will need to be rented to get out of the house

Please tell me who makes such nests on the rock. The photo was taken in July 2012. In the Elbrus region, on the southern slope of Elbrus.

Such nests are built by polist wasps. Basically, we have wasps of the Polistes dominula species, they like to make nests on rocks, but in your photo it is clearly not him, you are in the north. Do you live in America?

The photo was taken in the North Caucasus in Kabardino-Balkaria on the southern slope of Mount Elbrus. Moreover, I met such dwellings on stones there a couple of times - in the valley of the Terskol River.
Is it a wasp or a bee?

Wasp of course! This is usually the case for polylists, but I do not know what kind of view it is.

Species: Polistes biglumis.I've never seen him before(this species is very fond of settling in rocks, grass, shrubs, etc.

Judging by the pictures on the network, he has spots, does not look like!

Well, yes, you need to take a picture of the face, then everything will clear up...

Hello everybody!
Spring fotkal polistov, very similar to your Polistes bilgumis, but still it seems Polistes nimphus right?

Yes it is Polistes nimphus

Who has what kind of winter? Someone found female wasps?)))

I came across Paravespula germanica, the uterus, but it was dead and affected by a fungus (but it practically did not darken when drying! which I really liked)

Interesting, but where did you find it? Or just on the ground??? By the way, I need information for the site about wintering sites for wasps (I already wrote : under the bark, under the leaves, in the litter, in rotted wood), perhaps you know other wintering sites for female wasps? I will be grateful for the info. By the way, is there a VK?

under the bark of a fallen pine tree, at the base.

I even saw the uterus just lying on the ground in the spring)

Well it's in the spring
and in winter, wow, how hard it is to find...
By the way, why don't you go to VKontakte???

this is the big hornet's nest, which, unfortunately, can not be reached. it is about a meter high, and maybe more

a really big nest ... in a hollow oak tree??
here only a chainsaw to take in hand...

no, this is osina

Interesting)

Has anyone met the OS?)

vespa crabro, I met, and moreover, I already have a nest on my balcony, like a vulgaris!!!

Have you already lost your uterus?
