I was returning at night from a quiet bay in Koktebel - I heard a grasshopper several times. There are slopes on the other side of Biyuk Yanyshar, on the side of the Yuzhnoye-Ordzhonikidze highway, where grasshoppers can be collected in good numbers. There they seemed to crawl every 5-20m, that is, inhabit the desert slope. Last time I collected larvae on it in June, and they were only on rocky ...

Hello! I didn't find a topic to write in, so I'll create a new one. In general, I do not know any reference books on the Tyumen Region or the Khanty-Mansi Autonomous Okrug in general, perhaps the admiral was mentioned there... But for me, to see now (I write from the dacha) two admirals (one of whom I caught), it was such a shock! If I saw a swallowtail last year (and this year, too, yesterday ...

People, don't get distracted. Why, why and what kind of rubbish I will not discuss. Dima, there are people we know who need formalin, but they are not in Moscow right now. I will certainly buy, not a problem, a thousand more, a thousand less, but maybe someone else needs it, and there they don't sell it little by little.
