Wasp nests

Yes, they don't have much left until the end, be patient. Especially since they behave decently. And if you try to do something with the nest, indecency will begin.

You can't wait. An attic in a small house and a strong smell came from them. I assume that there is a lot of organic debris under the nest, and parasites are being introduced in it, which can spread through the house. There are still a lot of them left, the whole of September, and it depends on how October will be. During this time, they will breed such a party there that I don't know how long it will take to put the house in order after them.

In fact, they are unlikely to grow already, hornets finish the cycle early, especially since the "smell has gone". Where do you live? The end of the cycle depends a little on this, but in general you are unlikely to be able to transfer them This is a serious matter) so either wait the same or insecticide(

Yes, I live in the Moscow region. I found a company today, and they promised to cut down the hive without chemicals for a lot of money and take it to the forest... I hope that they can and will remain alive and well at the same time...

IMHO just throw off the nest in a special suit and throw it somewhere.. They will definitely not be alive and well, especially if the uterus has not yet come out - the ppc belongs to this nest both in the literal and effusive sense..

Well, imagine if others offer to burn or drown them exclusively... So at least they won't suffer, they'll fly away, maybe someone will stay alive and settle somewhere else.

Obviously, patience is not your strong suit. But dark fantasies about devouring the house by some mysterious hornet parasites are yours. I would just put a plastic wrap on the floor under the nest if something was spilling out, and be happy that such peaceful wasps were caught. Then you can put the empty nest in the cabinet.

Well, the nesting season of polistov is over. There are no broods in the preserved nests, and almost no adults. So, sometimes reproductive individuals arrive to spend the night or just sit during the day, leaving the impression with all their behavior that they no longer understand why they need it. The workers who fed them to the last are no longer there. It is worth approaching, and immediately fly away. For the first time in my experience, one secondary gallicus nest built after the primary one was destroyed by hornets gave at least some sense: about 10 reproductive individuals were successfully grown in it (and a couple of solid latibulus cocoons at the same time):

Obviously, the location of Kachim paniculata in the thick of the coplodium helped. the hornets couldn't or wouldn't break through this thicket. All the other gallicus nests in that area, both primary and secondary, did not survive to a natural death this year, mainly due to the attack of hornets. Several, however, managed to produce a small number of females and males before, the latter sometimes return for the night.

With the nests of nymphs, the situation is better: three nests have been preserved: two small and one huge, which lay down under its own weight on the ground. When it is completely abandoned, it is necessary to pick it up and measure it thoroughly. Another small nest, when it had already produced most of the reproductive individuals, was torn off by someone, leaving only one stalk. But this is clearly not a hornet, but a mammal or bird. In general, foraging hornets are not seen since the end of August.

For some reason, empty nests are very popular with various straight-winged birds.

In general, this year, probably due to the abnormally stable hot weather in July and August, polistov finished nesting earlier than usual.

Well, the season is over ...

Yeah. With polistami, it seems that everything is over, although both the nymph and the dominant fly. However, the second one is mostly in the city.
But the hornets continue to work. On September 24, he visited "his" summer nest in the wall of a country house, so the workers actively pulled out the dead larvae. 6-7 pieces were pulled out before my eyes and thrown almost under the tap. Now there are dried corpses ...
On September 30, workers and even a female regularly flew out of the same nest. However, I didn't notice that they brought anything. The larvae, apparently, have already dragged everyone out and just fly by inertia.
On October 1, Germanics are still actively flying in the north of Moscow. And the flight is clearly hunting.

Autumn-autumn.

Yesterday:





And you can't see the females, they probably already sit in winter shelters, only occasionally leaning out.

Individual vespula specimens are still foraging, although I don't know which ones, none of them have ever settled.

  
And the hornets near Moscow probably still work out the amount of effective temperatures, ours worked out back in September, you can't really find workers in the daytime with fire. I only saw a uterus that was hit by a car last week. Vespula workers still fly, but very little.

That's it, Hana...
Everyone seems to have worked out their temperatures. Neither hornets nor vespulas appear anymore. Until next year, I suppose.

Another nest of small eumenes on the grass:



The third one is already, this time not far from my house. In the past years in my memory, this was not the case.

I suspect that no one is home... I mean, the contents probably left this world. Well, a very suspicious crack...

And what exactly is the suspicion? On the nest, captured in the previous picture, there is also a crack in the lower part, although smaller.

Such cracks are a gateway for mold, especially during wintering.

Today's find. How much wood did I go through to find this - http://vespidae2012.narod.ru/hibernating_queens.html

As for the mold gate , it is debatable. According to my observations, if the brood dies (for example, from a severe drought) then, with the beginning of the wet season, mold grows even in nests without a single treshnik. The female does not sterilize either clay or food, by the way, I found this nest again and took it away, maybe this time I will still be able to remove the wasp.

Roman Rakochy, congratulations, I have never found wintering hornets, the only social wasps that live here. But the claim that it was the fungus that killed that female, and did not grow on the already dead one, requires proof. According to my observation, if you put a dead wasp in a small test tube and plug it (which is quite close to the conditions in wintering shelters), then mold will definitely grow on the corpse, regardless of the cause of death.

I also suspect that she died due to a leak in the shelter. The whole female was wet, after a recent rain, the water still seeped into the wintering chamber. Maybe that's why she died. Her" sister " on the stump was in a better place, which was completely dry. Interestingly, here is the percentage of deaths of females in shelters what? I didn't see any info on this anywhere. Yes, and the reasons too)

I didn't see the info, as a rule, they write about the wintering of wasps purely phenomenologically (they found it then and there, period). I tried to study it myself (not on hornets), but the data turned out to be incomplete and so far I haven't conducted an analysis. The only thing that turned out immediately: last winter, Polistes gallicus had a significantly lower survival rate than Polistes nimpha. It is almost impossible to find out the cause of death, because when you find a dead female, it is usually not only various fungi and bacteria, but even red-bodied mites have time to profit. And go find out who started it first. But it can be just frost or exhaustion. In general, the study of snake wasps turned out to be very difficult: as it turned out, not all of them sit in one place all winter. Most often, even in early spring, there is no one in the shelters found in late autumn. And in winter, during a strong thaw, you can see flights and crawling from place to place. But I'm talking about polistas, vespulas, it seems, "sleep" soundly, hornets, in theory, too, tozhe

If the weather permits, I'll go over some more tree stumps. I searched under the bark for half a day - only the larvae are large and there are a lot of crunches. And I carefully lowered this stump with the female and covered it with leaves. If it overwinters, I will go to visit from the beginning of April. I want to find out the temperature at the time of coming out of hibernation, if possible.

It is necessary to measure the temperature inside winter shelters, preferably with a "Thermochron", but only at the current pupaar exchange rate, it is better not to even try to estimate its price in hryvnias.

Larvae of crustaceans (in the narrow sense) develop in the ground, feeding on plant roots. And there could be something much more interesting under the bark.

Who is it then

Yes, who knows, with such a small scale. Perhaps bronzes (but not the banal gold and copper, but more interesting), and maybe even osmoderma.

and so. The larvae are very large by the way, it's a pity there was no matchbox

Such a larva clearly belongs to the lamellidae. And by the way, the larva of the crunch sometimes climbs under the bark.

Not exactly a crunch. Or bronzerka, from wood (spetsiossima, affinis, lugubris, etc.), or osmoderma. How they differ significantly, I do not know.

Also, someone unknown dug up a vulgaris nest, scattering honeycombs everywhere. It's a good thing the wasps completed the cycle before going bust - http://vespidae2012.narod.ru/vulgaris_in_ground4.html

This "someone unknown" could be both a ferret and a fox, and most likely, a badger.

N-yes, judging by the phenology, you have almost subtropics there.

Today, he hatched eumenes from one of the nests collected in the fall (if not the one with the crack, then I put it in a test tube under the balcony door for the winter). Oddly enough, despite the small size of the nest (10.5 mm on the largest axis), the wasp's caliber is not micro at all, but medium-sized, 15 mm in length (and if the abdominal segments are spread apart, then more). But we also have much smaller eumenes, I can't even imagine what kind of nests they should have.

Has anyone met Phyllanthus in Moscow / Moscow region? Where exactly?

February 27. - http://vespidae2012.narod.ru/early_spring.html

Wow) Well, at this rate, our pooolists will start building nests at the end of March

Hello everyone
I don't know how interesting this information is, but let me show you a photo of a wasp nest in the north of the Moscow province (under the roof of a building in roofing material).
Summer of 2016 .



Due to the fact that the nest was built over the front door, it was destroyed(unfortunately).

Polistes nimpha. But why destroy it? Tea nest is not in the room above the head of the bed fun, no one would be touched by them. In general, I am surprised at the pathological desire of residents of private homes to destroy wasp nests, which, by the way, greatly increases the likelihood of being stung.

Thank you for the information on the view. Unfortunately, the elimination of wasp nests (potentially dangerous) is associated with the likelihood of "contact" of people with an allergic reaction to bee and wasp venom, but I can reassure you that nests at a safe distance (under the roof of the same building) remain (every summer) unaffected.
Excess wasp nests are "removed" quickly and safely (at night) using an aerosol insect repellent.

I agree-it's a pity for insects, but people are more expensive!

Here-this contact is most likely just during such a liquidation, even at night. Polysts stung me only during manipulations with their nests, or directly with imagos. The most proven way to feel their anger the hard way is to bring your face up to the nest and at least lightly blow. Or tap on the socket. But the situation in which someone accidentally sticks their head or hand in the place shown in the photo, even if it is directly above the front door, I consider it improbable. For example, polist nests are very often found in the frame pipes of sports and children's playgrounds, clothes dryers, cemetery crosses, and at the same time 99.9% of people who use these structures simply do not know about the proximity of wasps. Children cheerfully slide down the slide, along the edges of which there are two pipes and four nests (one from each end of the pipe), the boys pull themselves up on the horizontal bar and similar "stuffing", and no one stings anyone. For me, the main thing is to visit such places only when no one is looking, otherwise immediately after I leave, someone will look down the chimney (suddenly I hid a treasure there), get scared, and ruin me. And from accidental ingestion of a feeding wasp along with sweets, the destruction of the nearest nests still will not save, since it can fly from anywhere. On the other hand, polysts bring great benefits to the garden and garden, as they hunt mainly for caterpillars and false caterpillars and at the same time know how to pick them out of places where few other predators will be able to reach. In the US, they are even specially bred for pest control. In general, IMHO your action is completely irrational.

Today (or rather. already yesterday) female founders of P. dominula began to gather at the sites of their parent nests, and serious battles sometimes break out during the establishment of the hierarchy:
