Interesting facts from the life of insects and other arthropods

Very interesting. I'll ask our lepidopterologists. It's funny that convolvulus is everywhere in bulk, but oleander is only on the coast in cultural plantings. Besides, mass migrations, I've never heard of them. And who is your manager, if it's not a secret?

Yes, only the climate limits the bindweed. And oleander - also fodder. But the flights of oleander in the temperate climate zone are generally isolated.

V. V. Dubatolov from ISEZh. You can't lure him to the forum right now: he's finally at the final stage of working on his doctoral dissertation
And as for the loach, it would be really good to check it experimentally - it's not difficult (where this type is common, for example, in the south of Ukraine-ow, Sealor! )

Steppe biocenoses-dynamics of their distribution. On the example of butterflies

to Helene

Is it in general or in a specific area?

  to Helene

Is it in general or in a specific area?

Initially, I wanted to limit myself to the European part of Russia (the border of forest and forest-steppe passes through Moscow, moving either to the south or to the north), but then I realized that this restriction is artificial, because large-scale processes cannot be studied within one region. But, on the other hand, it is also impossible to take the entire Palearctic, because Eastern Siberia has its own climate, its own cyclones and anticyclones, respectively, and biogeographic dynamics... In general, you can already get bogged down So now my strategic interests are in Europe and a little bit in Asia (south-western Siberia, northern Kazakhstan). That is, as far as the influence of the Atlantic reaches.

It's funny that convolvulus is everywhere in bulk, but oleander is only on the coast in cultural plantings. Besides, mass migrations, I've never heard of them.

Oleander hawkmoth (Deilephila pega).On oleander and periwinkle. Getting pregnant is more common in hot years. The development of butterflies is noted only in exceptional cases — on periwinkle. It is not known whether the butterflies that grew up here fly away.

to Bolivar:
About the migrant hawk moth..
..he was talking about the loach hawk moth. The oleander hawk moth, as well as several other southern (Mediterranean) species, are characterized by migrations, but only a few specimens migrate, while the bindweed migrates in large numbers. Therefore, where they arrive, a very large local generation is bred, and the illusion of a permanent population is created.

I once saw a mass reproduction of Macroglossum stellatarum in the southern suburbs of Moscow. Hawk moth fed on sinyak in May!!! and butterfly flowers in July. The next year, he was gone. There is no Macroglossum stellatarum in the Moscow region, but there is a permanent population in Moscow. What is this-a flight from the north? Probably, in the coming years we can expect the appearance of proboscis at least in the south of the region.

Why only on periwinkle? Just more often on oleander. I saw it on it. And the correct Latin for butterfly is Daphnis nerii. I've heard that butterflies fly away, or at least they can physically. But they may well stay and freeze.

Strange article....Wacky

Strange article....Stupid

It's a mixture of well - known facts-and, to put it mildly, dubious ones. As far as I understand, from the collection of research papers. Apparently, a troechnik from a non-biological university wrote What kind of garbage is not found on the Internet...

Since I was invited to the branch, this is the question:

And did anyone notice representatives of the steppe entomofauna in the settled territories within the North-West of Russia? Especially interested in Orthoptera. Among the facts known to me are the presence of Bryodema tuberculatum near St. Petersburg, Sphingonotus caerulans cyanopterus and Montana montana in the Luzhsky district of the Leningrad region.

Duckstepnenie just means the presence of elements of STEPPE fauna, as well as flora
It is in the North-West that I have little information (I would like, by the way, to get it - someone would invite me to St. Petersburg, or something... ). If you refer to the North-West of the Tver region, then there on the sands in the Volga Valley Pseudophilotes vicrama (alas, not Orthoptera , but a butterfly). But if you don't limit yourself to the Northwest, then I have something about straight-winged birds. For example, the point of B. tuberculatum in the Vladimir region. In the future, of course, I will pay more attention to straight-wings, since there is interest.
As for settling down in general. For me, with these "stepoids" (as E. M. Antonova put it about Vladimirskoe Opole-Yuriev-Polsky district), not everything is clear. On the one hand, steppe flora and fauna can spread quite actively in open areas, including agrocenoses - and "take root" where there are suitable conditions. Outside the forest-steppe zone, these are mainly well-warmed biotopes with sandy soil. The real obstacle for them is high - trunked forests. On the other hand, the current advance of the steppe people to the north (ugh, in" No Pasaran "propagandists of" global warming") is not the most significant in the historical time, judging even by the existing old reports. Populations isolated from the main range by large tracts of forests are clearly remnants of pre-existing ranges (I don't want to say "relics", because we are talking about the wrong time scales). That's what happened to the Pskov and Leningrad regions - it's not clear, maybe both (maybe modern recharge through the Baltic sands, or maybe refugiums). And the right-winged ones here, by the way, are very interesting for me, because they are much less mobile than butterflies (especially wingless ones).
Here is a report, thank you for your attention

Well, as for B. tuberculatum, it was found not just anywhere, but in the Duderhof Heights. As you can see from the description,
http://www.geo.pu.ru/ecobez/scince/npaspb/dudergof/index.htm ,
this place is quite unusual for the North-West (although, of course, it is not a steppe landscape). The peculiarity of vegetation is always noted for the Luzhsky district. Apparently, we can talk about refugiums in both cases.

PS About the invitation to St. Petersburg-I will keep silent for now, because now I do not understand the plans for the summer season, neither mine nor my entomologist friends. But closer to the summer, this topic can be tried and raised.

Yeah, we need to go to St. Petersburg, definitely Look at the light and fish there...

Specifically for the sediments of the Nizhny Novgorod region (meaning not the south, but the north-in the taiga area, the sediments are refugiums, apparently) - Polyommatus coridon, Melanargia russiae, Melitaea trivia, Hipparchia autonoe, Satyrus ferula. This is what I was catching myself .

All this is strange-Bryodema tuberculatum in the Leningrad and Vladimir regions... but in the Moscow region, according to the "Red Book of the Moscow Region", it is an endangered species (almost extinct), although we have a lot of suitable areas. How can I explain it? Or is this data incorrect?

2Dracus - we also have it very locally found. I had no luck meeting her at all

And where (Melanargia russiae, Melitaea trivia, Hipparchia autonoe, Satyrus ferula), Fixings? inter-drinking? Say Hipparchia autonoe, Satyrus ferula, really find.

Briodema in the Moscow region is not exactly an endangered species (i.e., its population/range is decreasing), but simply vulnerable - narrow-locality, stenotopic. According to observations in the Vladimir region, in our places it is not even very steppe: its point is a normal, practically not settled xerophyton on the sands, with a solid cover of yagel Why briodema does not sit wherever the conditions are suitable for it - it is impossible to say for sure. In fact, it is not far from the only one (in the sense of a narrow-locality species that occupies few of the suitable habitats).

And I'm all about Helene butterflies, you were right, the bindweed hawk moth, like the oleander moth, is a stray species, although it is not known whether it can winter here, at least in the south.

Are you sure there's taiga there? Or just in the Nizhny Novgorod region so called forest zone in general (well, as in Siberia, for example)? After all, usually such things do not reach the taiga, especially in Europe. If it's true that Taiga is already there , it would be very cool...
to Insect expert
I looked at the Podolsk "izofiya" and somehow doubted whether this is what I need First, this is a girl,and most importantly-she is somehow wrong, the ovipositor is not pointed in the subject, almost like a constrictus. Maybe true constrictus is an overgrowth (in fact, they are usually smaller). I was surprised that the isofia was in such a place... But with photos everything is much better: in any case, there is a typical boy And biotope, so it should be it. Later in the evening, I'll scan it and post it in the topic "Who is it"

to Helene:

Are you sure it's Bryodema and not Psophus?
I was also told about Tettigonia viridissima in
Vladimir Opole. This year, I found only
a similar species there - T. caudata in the Tasinsky Forest...

Briodema with psophus can be confused, of course. But it is unlikely that it was confused in relation to those points of the Leningrad region that I mentioned. After all, Miram watched, for example. Despite the fact that psofus is not entirely trivial there. And the Vladimir region is south of Leningrad.

Vladimir Opole - where is it?

to PVOzerski

Vladimirskoe Opole is in the vicinity of Suzdal and Yuriev-Polsky
Where you climb the bell tower and you can see plowed fields with black soil
(they say, however, that it is not real : - (
And Tasin Bor is already Meshchera, where it is easy to meet psophus and blue-winged birds.
Briodems like stony associations, not sandy ones

to Helene:

Are you sure it's Bryodema and not Psophus?

More than that. Adults are not easily confused. So that you can believe me, I will tell you the most striking difference: the color of the rear fenders. Psophus has a bright red fill all over the wing, only the top with a black border. In briodema , the basal area is pink-red, then a black sling, the top is transparent. Psophus (like cerulescens) is widely distributed in xerophytic communities, and bryodema is really rare. In our conditions - a desperate heliophile, just a cloud runs up - and they are already settled, you will not find

I was also told about Tettigonia viridissima in
Vladimir Opole. This year, I found only
a similar species there - T. caudata in the Tasinsky Forest...

These are much easier to confuse... and not even caudata, but another species of large grasshoppers (alas, I can't remember the name, but you will surely understand) - this species has very green specimens. I know that Viridissima must be assembled. Now the Insect expert at the exhibition of living insects explained well to me how to collect blacksmiths, I will see what is interesting - I will take

Well, viridissima's singing is unmistakable: neither with caudata, nor with cantans.
And green Decticus can be distinguished from them even by a layman.
You've convinced me about briodema. Can you share a point?

> Well, you can't confuse viridissima singing with anyone
, only it is desirable to look at the waveform On my own ear, only quieter and somehow "dirtier" than cantans. Apparently, due to two rhythmic components that are clearly visible on the waveform. However, I heard this animal for the first time this year - I grew it from a larva brought in May from Astrakhan.

T. caudata mistshenkoi sings, in my distant recollection, more like cantans than viridissima.

It's really hard to confuse decticus , both in song and habit. But gampsokleis, in principle, there are such - at first glance, the spitting image of tettigonia, however, not near Moscow. However, if you are not an orthopterologist, even an entomologist can easily make a mistake. One story with Sevchuk is worth something, I would also, say, not risk scattering some leaf-eaters or even babbling flies (which I still know a little better than the average graduate of the entomology department).

Speaking of viridissima and caudata , it always seemed to me that the green grasshopper goes further north than the caudate grasshopper. Was I wrong?

I'll share it, but I just need to dig up copies (my collection is a bit of a mess due to the problem with boxes that is currently being solved using Joiner) and write off the labels.
You're not quite right about tettigonias. It's clear from my singing, but unfortunately, I'm a layman in bioacoustics . And there are really questionable instances based on external signs, so it's better not to say anything until the definition is checked by a specialist. Especially after I actually misidentified the genus of wingless grasshoppers (I misunderstood the description of the trait in the determinant).

2PVOzerski: "Speaking of viridissima and caudata , it always seemed to me that the green grasshopper goes further north than the caudate grasshopper. Was I wrong?"
Viridissima is a southern species, which, as far as I know, was not officially registered in the Moscow Region.

And where, if it's not a secret? I live in the Podolsk district myself,
but I
didn't come across a green one north of the Tula region. True, I heard it in Desna 2 years ago,
but there was only one there, and I thought that this one was accidentally
imported with some seedlings...

Officially, by the way, this
particular species is registered (from the pre-revolutionary lists of straight-winged birds of the Moscow Region to
the relatively recent Chernyakhovsky list).
And the tailed one is not mentioned in them at all, although
it is also found in Moscow itself.

Caught almost the same place where I live. Exact coordinates - Ramenskiy district, near the village. Panino, near Bronnitsa (please note-the right bank of Moscow in the direction of tech.. Both of them are kept there almost exclusively on shrubs, the tailed one, of course, is much larger, and the songbird is several times larger than both of them combined (in recent years it has dominated there among grasshoppers). Caught 2 copies of green two years ago, then did not meet. I would have given you some copies, but, alas, I gave one of them to an entomologist I know (or rather, to his son's collection), and the second one was finally finished off by leatherworms earlier this year. However, I rule out a mistake - they are still noticeably different from each other.

Thank you, very interesting, I will watch it in the summer :- )
And the fact that we haven't met them for 2 years is not surprising:
they also have a long-term diapause, if the spring is cold
, then these southern creatures may not even hatch from their eggs.


And what will our dear colleagues say about the field cricket in
the Moscow region: it is on the list, but in real
life it is a baalshoy question. Rumor has it that somewhere in the vicinity
of Lytkarino... Tomilinsky forest Park... well, maybe, of course.
But this beast needs specific biotopes: so that the cover
is not 100%, and the soil is wet, and not sandy wastelands...

In a popular book by Brodsky and his co-authors, there is a mention of a field cricket in the Novgorod region. Also highly questionable, IMHO.

Officially, by the way, this
particular species is registered (from the pre-revolutionary lists of straight-winged birds of the Moscow Region to
the relatively recent Chernyakhovsky list).
And the tailed one is not mentioned in them at all, although
it is also found in Moscow itself.

About the fact that Viridissima is a southern species, I was told by L. Volkova , a Moscow nature conservationist who collects information on insects for the creation of protected areas and red books. I once told her by the way that I had seen and photographed viridissima, and she asked me to collect it next time, because there are big questions from experts about the existence of viridissima in the field-like they don't believe, they doubt the accuracy of the definition. The photo, by the way, turned out to be quite unsuccessful, it went into marriage
And also about the specialists. After all, I had already talked to Chernyakhovsky about briodema once, he was interested, and one of my friends and I specially went to Petushki to collect it. It turned out stupid: they didn't calculate the time, there were no adults, they tortured the larva - it turned out to be psophus, that is, the same garbage. as with pecilimon. Then we collected an adult, but by that time I had lost Chernyakhovsky's phone number
So with briodema somehow ugly turned out. Maybe now we should apologize, bring briodemum, and resume contact.

Here are the specimens of P. scyticus in L. Volkova, if they are not already lost.
(from Sobolev's collections made in the reserve on the Polosnya River).
The female is exactly, and the male m/b is given to Chernyakhovsky, I don't remember,
it was 3-4 years ago. She very much doubted that it was scyticus,
because at that time intermedius was also in the 0th category in the Ministry of Defense.

Also, for her (and for me), the finds
of Bryodema, Sphihgonotus, Podisma,T. viridissima, Conocephalus dorsalis,
Gryllus campestris, Leptophyes, Meconema, Platycleis, and Barbitistes in MO would be very interesting.
Since nothing has been mentioned about them in the literature for a long time,
and there were doubts about whether they remained in the region at all.

And still post an unsuccessful photo on the forum, maybe the blacksmith will
decide on it.

Barbitistes in MO.

Well, now it's clear to whom to give the unfortunate victim

And still post an unsuccessful photo on the forum, maybe the blacksmith will
decide on it.

No, it was completely blurry, and they didn't even print it.
