Interesting facts from the life of insects and other arthropods

Back in 1997, as I was leaving Moscow's Kursky Railway Station on a Simferopol train, I witnessed the following incident. The guide found a large full-winged female Platycleis sp. in a bale of clean linen. (the wings went far beyond the knees of the hind legs) - the view clearly came from "there". Naturally, the grasshopper immediately jumped up and was like that. All my attempts to be the first to "capture the sent Cossack" were not crowned with success - the first was the "good uncle", who with all care released a grasshopper through the window somewhere on the border of Moscow and the Moscow Region. None of our esteemed colleagues have ever caught large platicleys in the south of the Moscow Region since then?

If this is an allusion to all the steppe species near Moscow, then I, as a researcher, am offended.
And if it's just a joke, here's another one:
I recently got a collection from the PTZ-so that the butterflies were placed somewhere Judging by the quality of the material, this is most likely the result of student practice. Butterflies in newsprint bags marked with the date up to the time of day-this was probably the monitoring: when everything flies.
So, along with normal PTZ butterflies, two exotic saturnias lie quietly, also with a point and date, They went from the office of the reserve to the window: there the employees are fond of it And the students don't care who flew, they caught it. Both butterflies, by the way, lived, broken. I'm not going to spread my legs out and show you what they catch in the light.

In general, of course, there are deliveries. Such cases as with the grasshopper, as a rule, do not continue (after all, one female, even with fertilized eggs, is unlikely to be enough to form a viable population), but if, for example, a rather large number of clutches with seedlings were brought, and the climate turned out to be suitable... The last fact I know is that a few years ago, the Far Eastern moth Lahrerannis sp.appeared in Moscow. (I don't remember the specific name right now). The butterfly has clearly taken root, is spreading: it was originally recorded in Izmailovsky Park, and the day before yesterday I caught it in Khimki, so the gardeners have enriched the fauna, it's good at least the creature is harmless, and not some Colorado potato beetle

And who did the Podolsk "izofia"turn out to be?

And who did the Podolsk "izofia"turn out to be?

Female B. constrictus, very large and not quite typical. In general, I hurried to score... And when a serious conversation began, I got a good look at the ovipositor and realized that I didn't look like either Isofia or pecilimon.

Well, Barbitistes can be confused not only with isophyes and sawtail,
but also with Leptophyes punctatissima. However, in Podolsk these animals are unlikely to exist.
And where were they collected: in pine plantations or in settled areas?

Leptophyes has a very different ovipositor, it is difficult to confuse it.

By the way, today I was assured that they saw and even collected some representative of Odonturini in the Luzhsky district of the Leningrad region. I will find out the fate of the fees. I suspect that it will also turn out to be B. constrictus.

And what, constrictuses should be found only in pine PLANTINGS (on young pines, or something)? To be honest, I don't remember if I saw them on old or young pines (I didn't fixate on this, I forgot...).
As for the Podolsk point. The Lubyanka River Valley is a fairly narrow strip of open biotope between the river itself and the forest. The place is truly settled (i.e., not the steppe, but individual elements of the steppe flora). But these elements, I must say, are very southern (in particular, individual specimens of Salvia tesquicola are found - a rare plant in the MO, even in the most forest-steppe yugas). The butterfly fauna is also interesting - xerophiles such as lycaon, some mottled birds (trifolii?), which I still haven't bothered to accurately identify, but I can visually distinguish them - I haven't come across them in the forest zone before. Of the meadow species-Carcharodus flocciferus, also seems to be considered a southerner. Actually, it's a strange place. And when I saw a wingless grasshopper in the grass, the reaction was unequivocal: oh, not a fig for yourself! even so?! I mean, what I thought was an isophy turned out to be a pecilimon.
The forest there is uninteresting - mixed, obviously secondary. I don't remember the pine trees, but they must have been there, just because they are everywhere in those places. By the way, constrictus in such a poor forest is interesting in itself. Write in PM, we will arrange a meeting and transfer of the beast

> And what, constrictuses should be found only in pine PLANTINGS (on young pines, or something)?

Of my three B. constrictus finds in the Novgorod region, one was on the edge of a pine forest, and it was possible to call it young with certain reservations: it was clearly more than 10 years old. Two other animals were found in the spruce forest, although with an admixture of pine. Both were caught in the undergrowth after a strong wind, so I can't say whether they lived on pines or even firs. Now I regret that I did not check whether they can eat spruce needles

But this is already interesting. I haven't caught constrictus myself, but the literature
clearly states that they are related to coniferous trees, mainly
pine, because they feed on them. And in the Podolsk district, it is not difficult to find a non-planted
biotope with pine (well, in Yerino, perhaps). So, this species is not such an
obligate phytophage? That's for everyone. case of a good photo of a female on the Internet:

I don't want the beast itself, but I'd rather give it to Volkova. But if you still have doubts
about the definition, then scan this copy. right on the scanner - and in the forum.

So, this species is not such an obligate phytophage?

I didn't say that. Sometimes they still end up on the ground, but not far from the pines.
You won't be able to scan it (mounted, mustache and legs spread out - it will break), but it's better to send it for detection.
