Identification of Hymenoptera (wasps, bees, ants)

Tell me, which authors claim that pratensis specifically build a dome that is concave inwards, or, for example, that ants exchange information exclusively using odors? I don't know any of them personally, except you, of course.

In addition to fires and predators, it is obvious that there may be other factors contributing to the collapse of the dome in your area, such as weather (for example, a thick layer of snow) or edaphic (loose soil). But the very fact of frequent collapses does not at all indicate that "this is how it is intended." Here is what practical meaning can such a concave construction have in your opinion? Collect water? In your region, it is more likely to be diverted.

Where did I write about the concave dome at pratensis? Flat as a pancake or slightly convex, but not concave. (we do not consider damaged domes).
And this is not a consequence of some fires and cataclysms, as you think, but so conceived by the builders. About the frequent collapse of domes at pratensis in general, it is not clear where you got it from.
It is not clear why you attribute to me the view that ants " exchange information solely by means of odors." Where did I write this? Ants have different ways of transmitting information and signals other than smell (pheromones): behavior, postures, touching with antennae and paws, tapping the body on the surface, etc.
And since you are asking for a link to an authoritative source, please: "Meadow ant nests usually have a flat dome and a wide earthen rampart up to 3 m in diameter. Under the canopy of the forest, nests can also have a high dome..."(Dlussky. "Formica ants" p. 88)
And in general, too many emotions, Ilya. Take it easy.

Mdya.. here it is all the "professionalism" of this "competent researcher"

If you and Ilya have some long-standing problems of your own, you don't need to transfer them to this forum. Find yourself another venue for a showdown. My advice to you.

A Stepova panel, a flat dome, and a flat-topped dome are two big differences. You might as well call the table mountains plains, but they're flat at the top. The only difference is that if the top of such mountains is really flat, then it is still somewhat convex in the patensis ants, which can be seen in my (and not only) photos. Or is it necessary to outline the outline in a graphic editor to improve visual perception? But, of course, Pan Stepovoi knows better than I do about the shape of anthills of this type, despite the fact that in his life, as far as I know, he has never seen one. Well, how can such an insignificant fact prevent a true meganaturalist from once again brilliantly shaming the "Soviet okodemigs"?

I must have misunderstood the phrase about " a dome turned upside down and lowered into the ground." After reading it again, I realized that it probably referred not to the dome, but to the inner cone, although the wording is not obvious.

Yeah..
Ezox, I'll start with okodemigs, who is this here "sovkovye okodemigs", you, what? Have you ever seen a shovel, except in the sandbox? ))
Table mountains, it's okay, although all the same interseno, what is it, stem mountains, or pillars can be ? )
And the fact that I did not see these ants live has nothing to do with it, first of all, I found you two links to the photo, where the top of the anthill, designated as pratensis, is clearly concave, contrary to your claims to the contrary.
Well, the main questions, what is the difference between a flat dome and a dome with a flat top? I don't get it point blank.
And yet - if in the literature they write that the dome of parthensis is mostly flat, and Esox claims that it is normally convex, then I, as I have never seen these anthills, what should I believe?

The mountains are exactly dining rooms. I see Pan Stepova skipped geography classes at school.
As for the "sovkom okodemigs", but the pan has repeatedly stated that all our academic science is an obsolete product of the creation of a terrible and terrible "scoop", which deals exclusively with eating up budget funds, and not obtaining new knowledge, as opposed to the correct European science. And I belong exactly to her circles. So no mistake.

Yes, there are no concave domes on those links. It's just that Pan obviously doesn't know that in addition to the dome, the aboveground part of the formic nest also includes such an element as an earthen rampart. In the light of the fact that he has never seen such an anthill, this is quite natural and excusable. I haven't read Pasternak, but I condemn him.

all our academic science .......
And I belong exactly to her circles. So no mistake.

Aminazine, URGENT!

  

By email. There you vehemently denied the possibility of ants communicating with antennas and sent me to read the matcha. Should I quote it or not?

Read again what I wrote to you. I did not deny the simplest communication of ants with the help of antennae. I denied your opinion that each ant species has its own code (language), which ants use (by tapping each other with their antennae at different speeds) to transmit complex information to each other. You want too much from ants.
Their signals are simple and universal for many species: to touch, catch a smell, identify your own or someone else's, ask (offer) food, touching the mouth of another ant with their antennae. Perhaps something else is just as simple and versatile. But certainly not specific codes for a complex conversation that you wrote about.
Read again what I wrote to you and think about it. If you find the words (which you attribute to me) somewhere that "ants exchange information exclusively by means of odors", please remind me of them. Please let me know where and when I wrote this to you.

Communication implies the presence of a language, albeit a primitive one. post-groping to make sure that this is your own communication

Aminazine, URGENT!

It's hardly worth asking here. It is better to go outside and demand there. Maybe they'll give you a ride, or even take you to places where there's a lot of it.

Damn, you've already gotten in here with your squabble... I have almost stopped looking at the forum because of you two - wherever I look, everywhere ENO and Hierophis write to each other so much that it is impossible to read the forum between your swearing. Now even in this holy topic climbed, finish it!

No, Ilya has a different opponent here.
Alexander, there are a couple of Korean eumenins for you on the previous page. Take a look for fun - URL #7207

It's strange, I haven't looked at the forum for a month until the day before yesterday, however, somehow miraculously managed to clog it all with my swearing. But in this case, all complaints should be addressed to Roman, who now chose the pseudonym Stepova, who got involved in a discussion about the form of ants of a species that he himself had never observed, and in the end transferred it to his favorite plane-the discussion of neuroleptics. Where-where, and in this particular case I'm definitely not to blame.

Well, I'm sorry, Alexander, I'm certainly very sorry that I've been identified as the cause of your embarrassment, but at the same time I'm very glad that it's all about these little things, and not about even smaller ones, but some leptons that are so necessary when they're not there

Communication implies the presence of a language, albeit a primitive one. post-groping to make sure that this is your own communication

This is already a small step forward, compared to what you wrote by email. So I have to admit, you have flexibility of opinion, so keep it up. I just don't understand why you are so fixated on the absolute universality of signals for all ants - a very strange and unfounded concept. To begin with, I advise you to refer to the work of Pavel Iustinovich Marikovsky, dedicated to the study of component communication. At that time, the work on recognizing tactile signals transmitted in fractions of a second in the complete absence of appropriate recording equipment was really very difficult, as the author notes. Now, when such equipment, in particular, high - speed film and video cameras, has become quite accessible (even if not for everyone), a huge sea of material has accumulated that proves that the tactile language of ants is a very real phenomenon. And, to be honest, I don't see anything surprising in it, there are much stranger things in nature.

Would you be so kind as to recommend me any modern scientific work on the tactile language of ants based on the "vast sea of materials"?
And for the third time, I ask you to tell me where and when I wrote that "ants exchange information exclusively through odors", as you stated above.

Here and then:

The "ready to fight" signal (as you call it) is transmitted by smell in formics, not tactile. I repeat it again. I don't discuss how it "can" be transmitted. I'm talking about how it's transmitted in formics. The rest is just idle chatter. (C) Alex TimK <antvid@inbox.ru>, May 5 of this year

In this case, however, we are talking about a categorical denial of the possibility of only tactile transmission of the alarm signal. But you also denied any tactile signals other than the inducement to trofollaxis, in particular the involvement of tactile communication in establishing contact between the queens of social parasites and the workers of their hosts. I do not consider it appropriate to quote all this extensive fragment of our correspondence on the forum. In general, you have depleted the ant language to just one signal, and a language with one signal is not a language. Even single-celled animals are capable of such a primitive form of communication. You seriously underestimate the complexity of the information exchange of ants and other social insects.

In last year's article (Tan et al. 2014), a bunch of subspecies of Polistes rothneyi, including koreanus, were brought together as synonyms.

In the old Carpenter checklist (Carpenter, 1996), P. (M.) jokahamae Radoszkowski, 1887 is listed as a synonym of P. japonicus Saussure, 1858, whereas in the newer one, which is found in the web: http://iunh2.sci.ibaraki.ac.jp/wasp/polistes/Polistes.htm these are both valid views.

5. Is this Orancistrocerus drewseni ?


By the way, Alexander, in the Korean article on hornets (Choi et al. 2011) Vespa binghami for Korea is not given, it was found there later, quite recently? Or is this an extrapolation?
And what I caught in Korea, like Vespa velutina, which was first noted there only in 2003. These were more common than the others, and they would soon reach Primorye.

4. No, it's not him. Pay attention to the valvula of the intermediate segment - it is dismembered, and in Anterhynchium it is whole. This is the genus Stenodynerus, but I do not know the type, I do not have this in the collection, and nothing comes out on the key, since there are not enough angles. Probably S. clypeopictus, but not a fact.
5. That's right, this is it.

Please make it bigger. May 16, 2015 in the vicinity of Chisinau, Codru.

Probably a male Xylocopa violacea, as the antennae appear curved at the apex. But maybe this is a trick of the eye, bees are not identified as such.

Hurray! Finally published a long-awaited (at least by me) article with an illustrated key to the glitter of Northern Europe and the Baltic States - http://zookeys.pensoft.net/articles.php?id=6164

I've only looked through it so far, but my impressions are very positive

Yes, I already had time to evaluate it too-amazing!
And it's nice that even one of my articles was quoted.

It's strange, I haven't looked at the forum for a month until the day before yesterday, however, somehow miraculously managed to clog it all with my swearing.

Where-where, and in this particular case I'm definitely not to blame.

Well, I was also busy with other things for a month , so we met.

No need to get excited, because respect for the interlocutor is the key to a constructive discussion. Just because one of your opponents is constantly talking nonsense and scolding everyone, doesn't mean you should treat others the same way you treat them.

As for the communication of ants with the help of antennas or only with the help of smells-I share my observations.

I read somewhere that ants exchange information by passing liquid droplets to each other - that is, by chemical means, and decided to test this in practice. Near the anthill, formick dropped a caterpillar or a large horsefly with a torn wing and watched. The first ant that finds its prey begins to scurry, run fast, and attract other ants by its behavior. If there is no help nearby, he sometimes runs to the anthill and transmits information to the ants he meets. They understand it and run to the right place even when the ant does not pass them any droplet of liquid and does not even touch the antennae. It seemed to me that one ant understands the other from about 1 cm away or even more. Of course, I have no idea whether this is due to smells or antennas!

As I already said , I have a pratensis anthill near my dacha, which has a diameter of about a meter and rises slightly, i.e. it still has a small bulge. In different years, the ratio of earth, grass blades and twigs on its surface varies. Sometimes it is littered with blades of grass, and sometimes-almost bare ground. I.e. ants periodically bring any material, but probably also periodically drag it underground. As I said before, I brought them a whole package of materials from the abandoned Rufus anthill specially from the forest. I thought I had rufs, too, but they don't have enough building material. I dumped these sticks on their anthill, i.e. I did their work for them. But in about a month, the ants dragged almost all the sticks, most likely deep into the ground, and only a small number of them remained on the surface. I didn't take a full photo of this anthill, just a piece of its central part. This is in the year when there were a lot of sticks at the top.





And here is the Formica exsecta anthill. It is small compared to the Formica rufa anthill, but still domed, and made of thin blades of grass. Both rufus and Pratensis like thicker sticks. Why do exsecta prefer thin blades of grass?





And more. I again have almost near the dacha there is another view, which I have already shown here. Then TimK said that it is impossible to accurately determine the species from these photos - it may or may not be rufa, but it is definitely not pratensis or execution. I can only say that there are no large mounds anywhere in this area. I know almost every square meter of land in this area, so I'm pretty sure they don't live in a big mound like Rufus does in the woods. Next year, of course, I can find out exactly where they live!
Here is another photo of these ants.

In this case, however, we are talking about a categorical denial of the possibility of only tactile transmission of the alarm signal.

Right. In this case, I wrote about the alarm signal ("to fight", as you call it), which is transmitted by pheromones in formics. And you have transformed this answer of mine into my alleged statement: "ants exchange information exclusively with the help of smells." In my opinion, this is not correct.
If the next time you quote these words of mine, you omit the word "u formik" - again it will turn out incorrectly, since, for example, some arboreal species of ants transmit an alarm signal by tapping their bodies on the inner surface of the passages.
Now let's find out where I reduced all the tactile signals of ants to just one thing-the demand for food.
And so we will deal with it until you stop misinterpreting my words.
Either you will pass on my words correctly, or don't refer to me at all.
By the way, it is also not correct to give a link to a job where they ask for almost $ 40 to read it. If you've read it yourself, please provide a link to a free copy. You can even upload it to a file sharing site. Otherwise, I will think that you have just found this work on Google and, having skimmed only three pages in the public domain, proudly, with knowledge of the matter, advise me to read it in full.

Here is another photo of these ants.

I haven't read about the chemical method of transmitting information. Although, for example, if a forager sucks a little of its liquid out of the wound of this caterpillar and runs to the anthill to transfer this liquid using trophallaxis to another ant, then this liquid + the excitement of the transmitting one will most likely encourage the recipient to search for the place from which this food was brought. This is one of the methods of mobilization in ants.
Formica ants transmit signals not only with their antennae, but also by touching their paws, posture, behavior, and smell. Formics are mobilized in various ways. Most often, this is the excited state of one, the smell and rapid blows with the antennae. And then a part of those who are mobilized follows the one who mobilized them. And the other part only for a while showing excitement goes about its business. I think the reaction depends on the specialization of the ants. For example, intra-nest nannies will not go looking for food. Only foragers can be mobilized for food. But all ants react to the alarm pheromone, but in different ways. The female hides, the nurses grab the offspring and look for a safe place, the foragers rush to attack grabbing all suspicious ones. they can kill their own people on the sly. And so on. If the pheromone concentration in the air increases, the alarm increases. At some point, there may be a "panic" and ants (here I mean a serviformic, since I have not seen such a thing in the formic subgenus. There families are very large) leave the nest running in different directions. Nannies at the same time climb together with the offspring on the blades of grass. This often happens when attacking serviformics of slave owners (Amazons or raptiformics). After the alarm subsides , the ants return to the nest. In general, the life of ants is very interesting and worth studying.
All this is my vision of the situation and those who like to argue can not strain themselves. Stay with your opinion. I don't have the time or inclination to argue with you.
Why rufs are built from needles, and kaptoformiki from blades of grass-I do not know. But kaptoformiki, who appeared in families, for example, raptiformik and have never seen their native anthill-still build from blades of grass. I think it's in the genes.
I still believe that this photo is definitely not a pratensis or an execution. I can't say who exactly. Officially.
But I can advise you to look in the direction of serviformics in your ear. Something like cunicularia (if the body is bald) or rufibarbis (if it is hairy). Look for dirt mounds and mounds nearby and pick at them lightly. In most cases, you'll run into lasiuses, but these ones will also be close by. But I didn't tell you anything like that.

Transmitted. And punches, too. "To battle" is not what I call it, it is my "humanized" translation, but I call it an alarm signal. And yet it is transmitted not only by smell. I have already written about the results of my field experiment and I do not intend to repeat myself. I don't understand why you never bothered to repeat it. Like, "I don't believe in the paranormal, so I refuse to spend the night in a haunted house"?

  

I'm not going to change your mind about anything. Go in peace.

Thank you very much, Sasha. And what do you need to see in this Stenodynerus? We have a couple of species of everything here in Karelia, and I caught only picticrus myself. In principle, if there is a suitable key, I could take a look myself, so as not to bother with photographing.

Good afternoon, dear ones!

Is the beast definable? Samara region, end of June.

You're welcome, I don't really know them from around there... If I knew, I would have identified it. Try to run the insects of the Russian Far East through the Identifier, there should be Korean species there. Or take a picture of the top view and the first tergite (so that it is not obscured by the wings).

Good afternoon, dear ones!

The genus Halictus, I don't know any further - we may be able to determine it, but it's unlikely.

Please help me identify "malarial mosquitoes". There is no more decent photo, in every sense. Or rather, there is, but in the same spirit and quality. Didn't have time to figure out who they are ? "like they're already breeding, and she was glad they were busy with each other instead of me." They probably bite, don't they?

AVA, thank you! It turned out that the question would be more correct to ask in "Diptera".

And another moderation. An emotional dialogue about the communication of ants, which is important here, would be interesting as a separate topic.

Help me determine it.

Yes, it's a wasp. More precisely, the social fold-wing [Vespidae, Vespinae]. More specifically, the female hornet Vespa simillima.

The second one was found in dried cherry berries (6 mm )

Probably Habrobracon hebetor.

Yes, it's a wasp. More precisely, the social fold-wing [Vespidae, Vespinae]. More specifically, the female hornet Vespa simillima.
