Wasp nests

Hornets in burrows and anthills are interesting, I only found them in hollows and all sorts of dilapidated buildings.

Yes, the caterpillars of pigeons are quite similar to the caterpillars of the scoop-thick and similar in size. I thought that there were larvae of leaf beetles or sawflies hiding behind the murky glass in general. It became known about the diverse prey of discelia after Malyshev's work, before that someone also found only leafworms in their nests and honestly recorded it. Here, now it is known that this catamenes also harvests the caterpillars of pigeons, including, glory be to the great megaotkryvatetl Pan Stepova! A Nobel Prize for him!

KATAMENES-THE BEGINNING

And yet, yes, the current generation ?? (if so, then they even have three generations) already carries in the nests of other caterpillars, it looks like a scoop, this is plasticity )

But these nests are already not like dimidiatus, a common blanket, a completely different cell structure, completely different larvae! Et already on flavigulyarisov similar ))

So, part of the claims to the "Ympersky scientists" about the systematic affiliation of the composition of the katamenes production is removed? There is nothing unusual about" this plasticity " for Eumenine, as I have already noted earlier, it is amazing only for Pan Naturalizda.

The grain in the shadows on the last photo is notable, you can make flour! Pan's arithmetic about the generations of Katamenes is as incomprehensible to mere mortals as almost all of his speculations. A kind of ancient Ukrainian philosopher Hierophis Nikolaevsky Dark.

Meanwhile, an interesting phenomenon is observed in My megastep (TM): hornets for some reason left the remains of the polist settlement alone. Two nests were even rebuilt and re-sown. The hornets are doing something weird this year: they started destroying their nests a month earlier than usual and ended up doing the same. Although, perhaps, there will be a second wave.

Nicho is not removed there, it is most likely not the caterpillars of the scoop, but the caterpillars of the so-called sunflower fireworm And these are caterpillars not from the nests of flavigularis but from the nests of dimidiatus.
However, there is still at least one generation ahead.

And where is the hornet's nest in the last photo? I see a bird, I see a UFO in stealth mode, I don't see a nest. In general, the Panov system is not suitable for taking pictures of birds in the sky at all, it is very difficult there without OVI (or EVI) and autofocus.

That's all, the polistov hornets in the beam almost finished off: there was only one untouched gallikus nest and several more unpromising secondary ones, the nymph disappeared altogether. And in the spring, a total of about 100 nests of both species were laid on the accounting site. Hornet foragers prowl the grass like wolves everywhere. With them , the two Vespulas. But there are almost no polistas other than Dominula, despite such a promising start to the season. In another place-on a vacant lot, where the hornet was never seen, still not a single family of polistov or even the remains of nests could not be found, although in the spring I counted several dozen of them. I think that the birds did their best here: a couple of shrikes-cranes roosted there.

By some miracle, the aforementioned gallicus nests escaped the hornet attack. One, however, still bent to the brood of reproductive individuals due to the strong invasion of the rider Latibulus argiolus. From the second stage, males and reproductive females finish coming out, and there are no more larvae. There are three more secondary nests with larvae, it is difficult to say how they will end up. In the dense curtain of the prickly beetle, I found a large secondary nest of a nymph, there is no brood there, but only hefty young females are sitting.

It was not by chance that I started talking about the miracle: it turns out that this year the nearest hornet's nest is not in the forest, but twice as close to the polist settlement, at the bottom of a beam in the ground. By the post of foragers, who are especially many in the morning, I found the entrance:



I think that after completing the cycle I will dig, although the place is very inconvenient - in the rhizomes of reeds.

Well, in conclusion, today's photos of the eumenes nest on the Canadian goldenrod: the female decided, without further ado, to build it without leaving the dining table.




And finally, what, according to the laws of the genre, Pan Stepova should have made us happy long ago, but not fate.

It turns out that the wasps are fighting on the side of the DPRK with the American invaders and their satellites: https://news.rambler.ru/crazy-world/3771497...tsami-ucheniya/. I wonder what kind of view it was? Probably a hornet of some kind, there are several species of them that are aggressive towards humans.

No, a little aggressive. But those that can be disturbed and get an answer are either Vespa simillima or Vespa mandarinia. Judging by the descriptions of the attacks ("huge swarm", "pricks like needles") this is most likely the first one. If there was a second one, then no one would have thought enough there.
By the way, there could be Apis cerana in the forest, who knows.

So Apis cerana, as far as I know, does not sting a person practically, only gnaws.

I made a couple of free-time animations of a female Sceliphron curvatum collecting nest-building material in a spring. The collection process lasted only a few seconds, a little longer - the previous selection of the best mud. The earthworks were assisted by high-frequency vibrations transmitted from the wing muscles to the head, which were accompanied by short beeps.




Interestingly, Eumenes and Catamenes, which build nests from similar materials, have a completely different "technology": females take only water from the spring, and suck it in very quickly, in tens of seconds. The land is obviously mined closer to the construction site, moistened with regurgitated water. That is, unlike the scelifron, they only have to pull water over long distances, and inside, which is an advantage. On the other hand, scelifron performs fewer operations, so it's supposed to build faster.

So Apis cerana, as far as I know, does not sting a person practically, only gnaws.

There is a sting, so it can sting quite well (in my own experience, it stings). Another thing is that it is necessary to demolish a hollow tree by the root... It is "easier"to run into hornets.

Still, hornets and adult polistov devour:



In the picture, however, the male, but I think the female would be exactly the same.

Still, hornets and adult polistov devour.

Gee-gee, and who they don't "eat". Even spiders, crickets, dragonflies, ant lions, eumenines and bumblebees (although I only saw males )

The question is not whether it can master (almost any net insect, except, perhaps, armored beetles), but whether it wants to. The cuticle/meat ratio in polistas is not the most appetizing. If I were hornet, I'd look for someone softer and more meaty. But the power is there - no mind is needed, the hornet grabbed the first one who turned up on the inflorescence of goldenrod. However, this first one turned out to be a male. Whether or not hornets are really able to distinguish males of other wasps from females, for example, by smell, is a question. You need statistics to answer this question, but one observation won't help you here.

Meanwhile, another predator polistov drew:



On the topic of building Eumenin nests, phase 2 of the "technological process": belching water on clay and collecting it.

Hierophis, unfortunately, I can't say anything about German wasps and honeycombs in hornet nests, my main hobby is completely unrelated to insects (electronics), I didn't do a deep study of wasps, although I've also been fond of them since childhood, somehow I didn't think to divide them into different species, I just watched behind the nests. Yes, the queen really quickly found a nest, after I removed the old one, it didn't hurt her at all. I wonder who could have hollowed out nests from stumps, maybe some animal or bird? I once came across a hornet's nest in the garden, so there was a whole swarm of wasps there, I carefully covered the hole, but they still flew away from there. Added snapshots: 1. Two old wasp nests and a new one between them, 3L jar for scale. 2. Opened the left large nest, you can see 5 tiers of honeycombs. 3. An old hornet's nest and another abandoned one.

Wow, how long have they been building nests?

As much as any other in the temperate climate zone of Eurasia - from spring to autumn.

I found a unique place today: on an area of about 10 square meters, there are six holes in the ground, and each one has a germanic stream. It's neither six different nests, nor a single super nest. By winter, I'll try to dig in. So far, foraging is in full swing, including meat is worn. And the "trumpeters" at the entrances are buzzing loudly - the place is on a sunny slope, the grass is burned, the ground is heating up strongly, you need to ventilate.

Hello, dear forumchane!
I found this forum when I was looking for information about the life cycle of a hornet's nest.
About 2 months ago, wasps started up next to my window, under the roof tiles. During this time, they have actively expanded there and are not going to leave, it seems, because some people constantly monitor the tiled roof for "where else to climb". At the same time, they can circle up to 30 os, and fly back and forth in batches.
Please tell me what to expect next. How long will the wasps be there, is there some kind of nest cycle after which they leave the house, or is it already forever (it is quite problematic to drive them away, and the roof is large)?
I didn't find any clear information on the Internet.
Sometimes it gets creepy, to be honest… They are no more than 2 meters away, i.e. a very short distance, and sometimes they fly on the net and sit. I read that they can chew through it...
I will be very grateful for your answer.

It would also be nice to see what kind of wasps are, and find out where all this is happening.
But in any case, don't worry. It's already the middle of September, and the wasps won't stay much longer than the end of it. They won't nibble on any nets - it's not their food. And with the first cold weather, they will all die and never come back to you again.

Well, our hornets are "squeamish" about beetles, but V. mandarini a doesn't care. They even disassemble large barbels into gears without any problems.
As for wasps, our hornets crush vulgaris, Germanic and Saxon regularly. And not males, namely foragers.

I found a unique place today: on an area of about 10 square meters, there are six holes in the ground, and each one has a germanic stream. It's neither six different nests, nor a single super nest.

Well, the males have gone. So winter is just around the corner.

Thank you so much for your reply! There is a video, I will try to insert it in the message.
Everything happens in Western Europe, where it is not very cold in winter, during the day (+3), at night (-5) minimum)) that's the whole winter.
Under the roof, they will probably be warm there at all, people live there, the heating works.

This is a German wasp-Vespula germanica.
Active years because the family has increased to the maximum size. But you can't escape fate. For an active life, they need a temperature above 15 degrees. So by October, everyone will be finished anyway. And no amount of heating will save them. These wasps have annual families even in the tropics.

They have been flying with us since September 3, and winter still hasn't happened. But, of course, unlike the well-known Western Ukrainian naturalism, I do not harbor illusory hopes that at least this year it will be canceled. But all in good time. So far, it is summer 2.0-about +30, sunny, windless.

Or maybe by December, depending on whether it's the south of Western Europe or the north.
Not everywhere.

By December, it is rare even in Italy and Spain.
But Germanic annuals are everywhere. In New Zealand, it's a completely different story. There is no such thing anywhere within its natural range.

Somewhere in Africa, as if not in Algeria, they observed a two-year-old. In November, Germanic foraging is not uncommon even in our country. What information do you have about southern Spain and Italy? In theory, they should live there until January. Of course, not all of them and not every year, but nevertheless.

ENO and AVA, thank you for the clarification, you reassured me)) I don't know what the actual temperature will be, but in any case it won't be +15, that's for sure)) Now I will watch them without panic))
When a heavy rainstorm starts, all the hard workers fly home, and so many of them go inside that I can't even imagine how many there are in total... Probably a few hundred for sure. I read on the Internet that wasps can attack for no reason, so I was worried.
Sometimes you can even see how they wear insects)) A little flying, poor guy, but keeps that bug)) Funny)
I hope they'll choose a different location next year))

At this time of year, the bill in a strong family Germanicus is no longer in the hundreds, but in the thousands should go. But no animal attacks without a reason. In the case of wasps, the only reason is a direct and obvious threat to the nest. Don't get too close, and most importantly, don't breathe inside the hole where the wasps fly out, and everything will be fine.

You can't lure me close to it with anything)) It is better to be friends with such neighbors from a distance)
thank you very much!

We've had some male hornets fly out. They visit a public aspen-fly watering hole, although I have never seen any females/workers of this species there. Now it remains only to wait for the departure of the males of vespula vulgaris.

And we have male hornets, Germanic hornets, and vulgaris appeared last week, and now they are actively flying, especially hornets. And the foragers of vulgaris pull out the larvae with might and main (like, there is no need to feed in vain).

The release of larvae is an interesting phenomenon and not entirely clear. Is it the cause of their death or the consequence? Polysters are more likely to have an investigation: they usually throw out the already dead or dying. I don't know how to do this with vespulas, their nests in natural conditions are almost impossible to study from the inside (or rather, so far no one has created any clever invention for this).

The pan went berserk in his Maidan completely. Even the human language has forgotten.

Winter crept up on us unnoticed, and replaced summer in less than a week. Autumn as such has not happened and is not expected in the near future. The temperature is no more than +12 at noon, at night it drops to +4. The wind doesn't stop for many days. It only rained once in September. Another negative temperature anomaly coupled with positive aridization. There were three cripples at the wasp spring yesterday, including the first baby queen germanica seen of the season. No one collected clay from the slope at all. And this is in a sun-warmed calm, where the temperature is ten degrees higher than the draughty one on plakor. Almost all the reproductive female polistas gathered in wintering shelters.
The Vespulae still forage somewhat, but this is only a shadow of their former activity. There were only a couple of flowers left in the ravine, and there were only evilheus, flies, and sleepy melifera on them. There is no OS at all. It remains only to remember the past and rivet animations.

It was freezing last night. In the afternoon again windmill, again +11. But the Germanics don't care - foraging is in full swing. Workers hunted flies on the few remaining Seseli tortuosum flowering plants. Other workers and males of this species also ate nectar on it, as well as a couple of species of small cerceris, some small pompilida, and a single female P. dominula. But Eumenin did not meet any.

And in the flowering thickets Diplotaxis tenuifolia met a female philanthropist trying to hunt. But, alas, not a single melifera was there, so the "wolf" unsuccessfully threw herself at the babblers and tahins. Nearby, I noticed the still-open filant burrows.

I visited a familiar spring, everything is sad there: a pair of Germanic males and another of their long-dead brother. Occasionally, workers of the same type arrived. But for some reason there was no vulgaris at all, as well as polistov, and any other operating systems. Most of all, it was Melifer. It was even interesting: why do they need so much water in such a cold weather? They also feed on nectar, where there is already more than enough water, and it is even necessary to evaporate the excess to make honey. All our other bees have enough water from their nectar, even in hot summers.

Clay, of course, was also not mined, only the lyrises dug winter burrows in it. The goldenrod was empty again. I found a certain variety of wasps only in the schoolyard in the thickets of flax: here and podolonia, and ammophila Hayden, and a male eumenes of some kind. I was surprised by the presence of ground bumblebee workers there, the young queens have all been lying down for the winter for a long time, and these are all working.

Today (or rather, yesterday) I found a hornet's nest in the hollow of a burnt willow tree with as much as one piece of wood. Found pieces of royal honeycomb pulled out and thrown by a bird or animal. I also finally met a male vulgaris. His photos, however, turned out, as Pan Stepova likes to say, to be sanctioned, since neither the camera nor the insect liked the sudden rain that fell.
