Can you tell me what it might be? There are no photos and the description is very uninformative. I saw them 3 times in my childhood, about 10 years ago, in Turkmenistan, Ashgabat, so there is no photo. A large insect with a body shape very similar to a wasp, matte black in color, I do not remember that there were stripes and other significant pigmentation. Large, about 40-45 mm (at least much larger than Vespa orientalis). Once I saw it on a tree crawling into a nest, the second time-when it was eating grapes.
You can't say for sure, it's understandable, but is it possible to determine which gender? Very similar to the carpenter bee, a photo of which was given on the forum, but according to the recollections of that insect, the body was narrower.

It may be F. auricularia or F. tomis (Kolenati, 1846). Females differ poorly, and you can try to distinguish them by the structure of the antennae:
for tomis: "the 4th segment is 2 times longer than its width, 1/3 shorter than the 3rd; the 5th segment is almost 1.5 times longer than the 4th and slightly longer than the 3rd" (Bey-Bienko, 1936: 137);
for auricularia: "the 4th segment is much shorter than the 3rd and slightly longer than its width, usually almost spherical, the 5th segment is slightly shorter than the 3rd, two or less times longer than its width, almost cylindrical; subsequent segments, starting from the 6th, thicker and much longer than the 3rd or 5th segments. " (Bey-Bienko, 1936: 152).
