Question

Thank you, Marián

Answer

Thanks for request. Thre are eggs of Corythucha arcuata, commonly known as the oak lace bug, on oak leaves. Is a species of true bug belonging to the family Tingidae. It is known for its distinctive lace-like appearance on the leaves of oak trees, caused by its feeding activity. This insect can cause damage to oak trees by sucking sap from the leaves, leading to yellowing, wilting, and premature leaf drop. Best regards M. Zubrik

Question

Hello, I have a problem with the gales in the images! I thought it could be Dryomyia circinans, but after a while the adults appeared, they are clearly Hymenoptera. Can you help me with some suggestions? I also have another type of gale, I am sending a new message. Thank you!

Answer

Dear Ana, thank you for your question. Yes, galls on the leaves looks like those caused by Dryomyia circinans. However, I see at least one gall that belongs to Neuroterus lanuginosus, which is Hymenoptera. The wasp on your picture is definitively not a Neuroterus species. I do not know, what a species it is. Maybe some prasitoids or some another gall wasp... Best ragards M. Zubrik

Question

country is Romania, but is not in the list

Answer

Dear Ana, thank you for your inquiry. Identifying this hairy object is no easy task, but it appears to resemble a gall. There are several insect species that induce galls on oak trees. Generally, they belong to two groups: hymenoptera and diptera. This particular specimen resembles a gall induced by the Hymanoptera species  a gall wasp, Neuroterus lanuginosus. However, it cannot be ruled out that other factors may be responsible, as the symptoms are not unequivocal. Wishing you a pleasant day, Milan Zubrik  https://www.forestpests.eu/pest/neuroterus-lanuginosus

Zdravím,   ide o hubu uhliarik pálený Ustulina deusta. Huba spôsobuje hnilobu hlavných koreňov javorov (ale aj bukov a iných drevín) a je veľmi nebezpečná, kedže po pár rokoch sa strom vyvráti, kedže koene budú úplne vyhnité.   S pozdravom,   Andrej Kunca

Thanks for request. This is a nest of the pine processionary moth Thaumetopoea pityocampa. It is a common species in a Mediterranean area. I can cause defoliation of the tree. Be careful on hairs of the caterpillars. They can cause an allergic reaction on human skin! Best regards MZ
