Zdravím, tie čierne krustovité podkôrne koberčeky by mali byť Biscogniauxia nummularia. To, čo je na kôre čierne v strede fotky, nie som si istý, či je to to isté, alebo tam bolo niečo iné.

Dobrý deň,
pekné fotky. Aj keď neviem odhadnúť veľkosť larvy, mal by to byť chránený fuzáč veľký.
U nás sa ešte pomerne často vyskytuje na odumierajúcich duboch.

Dobrý deň. Diery na borke smrekovca boli spôsobené ďatlovitými vtákmi, ktoré pravdepodobne vydzobávali larvy fuzáča smrekovcového (Tetropium gabrieli). Tento fuzáč je najbežnejší škodca z z čeľade fuzáčov na smrekovci. S pozdravom JG
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
