Answer

Dobrý deň, ďakujeme za dotaz. Áno, máte pravdu, jedná sa o jedného z uvedených druhov. Nie som si bôbec istý, že ktorý z týchto dvoch druhov to je, nakoľko sa to podobá trochu na jeden a trochu aj na druhý druh. Ale prikloním sa skôr k tomu, že to je kôrovnica smrekovcová. Pekný deň M Zúbrik

Question

on Mespilus germanica on thin part trunk/first branches. Lg on pictures excavated by woodpeckers. LG zigzagging deeply sunken in the wood, severe damage, but tree still alive. d-shape exit holes 3,5mm wide. not all exit holes are neatly d-shaped.

Answer

Dear Froukje, thanks for this question and a nice pictures. Yes, the gallery seems to me very much like gallery system of Agrilus sinuatus. This species is very probably the author of this gallery. With best regards M. Zubrik

Question

large feeding galleries, d-shape exit holes. Could only be agrilus ater? by description agrilus suvurovi could fit. but cannot find a trace or even acknowledgement of existence in the netherlands. is it a new species?

Answer

Thank you for your request and a nice pictures. Yes, it is absolutely sure, these galleries and exit holes belongs to some species from the genus Agrilus. I think it could be A. ater, that is already known from Netherlands. See: https://www.tuite.nl/iwg/Coleoptera/Agrilus_ater2017.pdf. Best regards M. Zubrik

Question

mating room visible. single mothergallery often hooked shape up to 10cm, 1mm wide. larvagalleries far apart, about 3,5 cm long, 1mm wide. maybe have been a different tree: like abies.

Answer

Hello Froukje,thank you for very nice photos and detailed description with dimensions of galleries. I think that it is gallery of genus Pityophthorus. If it is spruce may be P. exsculptus. However, an exact determination is not possible. Many galleries look alike, and if they are older, it is very problematic to determine the species or even the genus. If possible, please try to determine the exact species of host tree in the future and send several photos of the entire gallery. Fresh galleries are more suitable for determination.Best regardsJozef

Question

Callidium aeneum?

Answer

Dear Froukje, thanks for your inquiry. I want to encourage you to map species using this internet tool and send us your nice pictures. Although it seems that we are not able to identify most of your questions down to the species level. We are not taxonomists. We are a group of people who deal with forest and tree protection. Our goal is to help the owner recognize the cause of the damage, wilting or death of the tree. So I want to help him to take such precautions that will save the given tree, or prevent it from attacking next trees in the vicinity. From the point of view of forest or tree protection, it is not always necessary to recognize exactly what kind of beetle it is. Knowing that it is a bark beetle and not a fungal pathogen is often enough for the tree owner to take apropriate control measures. Just as the determination of species based on external morphological signs is complicated, the identification of galleries or feeding traces is even more difficult. Only a small part of galleries, wounds, damage, etc. it has such signs, on the basis of which the cause of the damage can be clearly determined totally exactly. Not all they are fully species-typical. I have some suggestions for you if you want your requests to be more exactly determined. Please try to send more pictures of dying trees, not totally dead trees. Try to capture more different symptoms, however remember, that to have a picture of the adults (in the case of insects) is always the best for species identification. I think that galleriess on the pictures were caused by some Cerambycidae species. They look very much like some Callidium galleries, but I can not say which exact species it is. With best regards, M. Zúbrik
