Agrilus planipennis is an aggressive beetle native to Asia, which has recently invaded North America and central Russia. In European Russia, the first specimens of A. planipennis were collected in Moscow in 2003 and the Moscow Province is therefore thought to be a likely entry point to Europe. The pest spread along roads and railways and, by 2013, it was recorded in 11 provinces of Russia. The goal of this study was to clarify the current northern range limit of A. planipennis. To do this, ash (Fraxinus excelsior and F. pennsylvanica) trees were surveyed along the federal highway M10 (Russia) between Moscow and Saint Petersburg in July 2016. The condition of ash trees and presence of A. planipennis was recorded at 15 locations. We found dead ash trees with galleries of A. planipennis at six locations (56° 27.799’ N; 36° 35.383’ E to 56° 47.665’ N; 36° 03.584’ E). At the more north-western sites ash trees became infrequent and signs of A. planipennis were not observed on any ash tree. Beyond the National Park
