Tetropium gabrieli is a species distributed in Central Europe and some adjacent areas like France, Germany, Great Britain, and Denmark. It develops in European larch (Larix decidua). Larvae feed under or in the thick bark of diseased or dying trees, in standing or fallen trunks and in thick branches. Tetropium gabrieli is a crepuscular nocturnal species.

In Central Europe, it is spreading faster and faster in planted larch woods throughout the territory after World War II. In addition to technical damage, it causes accelerated attack of the white part of the wood by fungal infections. It is primarily a secondary pest, but it is certain that it also participates as a physiological pest in further weakening and death of trees and is currently one of the common and serious European larch pests [✧][❖].

Despite its common occurrence in Central Europe, T. gabrieli was described relatively late, only in 1905 by Julius Weise [✩].
