Distribution

Species native to the Oriental and Eastern Palearctic Regions, established in North America ( Gomez et al. 2018, Smith et al. 2020) and Italy ( Colombari et al. 2022, Marchioro et al. 2022). This finding further extends the distribution range of the species.

Notes

Cnestus mutilatus is a somewhat polyphagous species ( Ruzzier et al. 2023b), including plants of economic/productive relevance (e.g. Mandelshtam et al. (2019), Ruzzier et al. (2021b), Monterrosa et al. (2022)), yet its host plants in Europe were not known. The specimen on which the report is based was found in a tunnel bored into a branch of an unidentified conifer (probably Abies ). This is the first observation in which C. mutilatus was found in association with a conifer; however, it is plausible that this plant might not be a reproductive host.
