Hello, thank you for your inquiry. The attached photo shows the adult beetle of the species Monochamus galloprovincialis (female). Its larvae live under the bark of pine trees. Best regards, M. Zúbrik
Dear Ignacio, thank you for your reguest. I think on the pictures are galleries caused by Monochamus galloprovincialis - the black pine sawyer beetle. It is cerambycid species. Larvae lives under the bark and pupation take place in the wood. It attack weakened trees. The adults maturation feeding can damage the twigs. It was recently found to be the vector of dangerous pathogenic pine wood nematode Bursaphelenchus xylophilus. With best regards M. Zúbrik
