Any idea about this young gall on oak (about 4-5mm)?
Thanks a lot.

Dear Muhabbet: some Tephritis species can enter stems of Tragopogon, Saussurea, etc., from flower heads causing swellings, for instance, Tephritis mongolica at 4000 m in your motherland and in Kyrghyzstan, and this looks to be a similar case, but Icannot tell the plant, and furthermore, cannot insist it to be a Tephritis.

Any ideas anout the plant?

Dear Valery,
Many thanks your your interesting comment. The plant is Quercus sp. It is very small, therefore we could not comment weather it is young or grown. Should it be preserved in capture, or let it for further developing in its natural case. The place, where we found it, is very far from Van (ca 200km South), in a quercus woodland within currently unsafe territories.

If the left "flower" is another gall, then this is probably a cynipid. Do you insist that the left exuvium belongs to a dipteran?
