Thread subject: :: Psylloidea on Ulmus laevis ?

Posted by Joerg Brucklacher on 08-04-2021 11:34

last year (15.06.2020) I visited the only Ulmus laevis I know in my district and was suddenly surrounded by thousands of jumping lice ...?
Southern Germany, 430 m

Got them into nose and hair, and managed to take a few bad pictures. Are these Psylloidea ?
