Hello Ilya,
I just read this:
( http://www.ukflymines.co.uk/Moths/Coleophora_lutipennella.php ).Distinguishing between the final cases of Coleophora flavipennella and Coleophora lutipennella on Oak (Quercus) is not possible [...].
Is it sure that Coleophora lutipennella doesn't occur at your place?
Best regards,
Tina
