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
Thank you very much for your inquiry. Upon observation of the tree, there are signs of the presence of some species of Cerambycidae - longhorn beetles. However, from the picture provided, it is not possible to determine the exact species of the beetles. It is important to note that these beetles typically only play a minor role in tree decline, as many of them are strongly secondary pests that attack and inhabit weakened or damaged trees. Therefore, in this case, it is not possible to determine the exact reason for the mortality of the tree from the picture alone. Thank you very much and have a nice day! MZ
