Well, I can post some more photos. This is Ruspolia nitidula (Scopoli, 1786). The species is known, but I think it is appropriate to post it here, because in the photos you can see important systematic features. Unfortunately, the photos are not very beautiful, but they are informative. Ukraine, Kherson, late August 2010. On an abandoned wasteland outside the city in the tall green grass.

I try to display on the photo not only the beauty of wildlife, but also morphological features that are important from the point of view of taxonomy. And I also really like it when such photos of rare and not found in my country species are posted on the forum, which show all sorts of subtleties of the anatomical structure. And I ask everyone who puts out views on the definition, to photograph in detail the venation of the elytra, the cerci, the subgenital and anal plate, and other subtleties. Or, at least, from different angles and in high resolution.

Sedakov is cracking up here, now I know his song. In general, on amateur video recordings, you can find a lot of information about poorly described species. The main thing is to find them.
I think the loudest European erect-winged birds I've ever seen are drymadusa, then the field cricket, and only then tettigonia viridissima. But I do not know how loud the gumpsokleis squeal.

Yes, you can find some things, but unfortunately, it often happens that the rarer the view, the lower the quality of shooting (the law of meanness). I have a number of site addresses where there are used.m. good photos.

I've never heard drymadusa chirp, but I do know that Ruspolia nitidula is louder than a field cricket. His singing sounds to me like the sound of a chainsaw. And his song is quite similar to the song of grasshopper Sedakov, which I just listened to on the video (although I don't know how much the real song differs from the video recording). For a long time I could not find Ruspolia chirping in the grass at night, and for a long time I wondered what kind of insect was making this loud sound. I even nicknamed it grasshopper-circular saw, until one day, without setting a goal, I tracked down in the grass late at night, first one singing male Ruspolia, and then another. I was very surprised how such a small insect (no more than 5 cm) makes such a loud, ear-cutting sound! If the male is in good shape, then the ear can be laid, if the head is brought close.

Alas, I haven't searched for many similar biotopes (and this year I managed to visit many interesting places in the region). according to my nickname) - all nonsense!??
Our oldest teacher at the department Stoiko T. G. collected a lot of insects in the Penza region-claims that she often came across larvae that she referred to as isophyas... But, she saw an adult insect for the first time (what I caught-it turned out that on that trip we went together) for all this time!!?
I have been collecting / studying insects of the region for probably 20 years, but I have NEVER come across such specimens (see the photo of 2 females and 1 male)!? Over the years, I have accumulated a fairly large collection of erect-winged birds, where I paid a lot of attention to long-whiskered birds and sawtails in particular. I think I need to put them in a single box (two boxes) and look similar to isophy... But, I think such small larvae (2-3 cm) can not be determined before the species... Who is currently engaged in right-winged animals in the Volga region (???) I don't know. It seems that there is a graduate student in Kazan, it will be necessary to write off with her... Very interesting data on isophyas and sawtails are provided by Prisny in the Belgorod Region CC (Tomsk). I'm also thinking of selecting candidates for the new edition of the Penza Region CC , but first we need to identify and analyze all the collected material.

There are also sevchuki periodically caught - what kind of species is this?

Well, good luck processing your material. If you are in doubt when determining the types - spread it out! About isofiy - a very interesting story. Of course, they are there - in the very place where you found the first three individuals, but their population density is not high, and individual individuals hide very well.

Only two species are found in Russia - Onconotus servillei and Onconotus laxmanni.
Вот Onconotus servillei Fischer von Waldheim, 1846:

But Onconotus laxmanni (Pallas, 1771):

See the difference in the shape of the pronotum? The pronotum narrows in the anterior part of the Servillian beetle and therefore has an ovate b.m. shape, while in the Laxman's beetle the pronotum is of equal width in both the anterior and posterior parts. Therefore, the shape is more like a rectangle. Your species is Onconotus servillei.

Yeah!

Well, who defined these types? In general, this is a typical problem of all small local history museums of regional significance (almost every city has its own small department for flora and fauna).

In the book Yakobson G. G., Bianchi V. L. Straight-winged and false-net-winged birds of the Russian Empire and neighboring countries. SPb., 1905, there are very realistic illustrations. The images are very similar to real views. There you can also find tolstun mnogobugorchaty. Imagine that the artist who painted this animal saw it firsthand-alive.

Edited by: oops, a mistake! In the photo - another species of fat man-Callimenus oniscus, which is not found in the ex-USSR countries.
