Alexander, I wrote it on my smartphone and the message was automatically edited, and I didn't check it. Cossus cossus.
Hello, Alexander.
This is the wife of Yury Semeykin.
Today I talked with Yu. A. Chistyakov, to whom I gave the stump in which this caterpillar hid. The moth hatched from it, but it was deformed, however, Yu. A. Chistyakov confidently identified it as Acossus acossus.
All the best,
Elena
