The first records of Xyleborus dryographus (Ratzeburg, 1837) (Coleoptera: Curculionidae) in Sweden

Abstract

In 2020 and 2021, the first findings in Sweden of Xyleborus dryographus (Ratzeburg, 1837) were made in the province of Blekinge in South-Eastern Sweden. In 2020, two specimens were caught in interception traps baited with pheromone, primarily placed out to catch Platypus cylindrus in oak stands. In 2021, two specimens were caught in a pitfall trap near oak logs placed out to support populations of Lucanus cervus. The distance between the most distant localities is 2,4 km. The findings indicate that X. dryographus is now established in Sweden. The number of known bark beetle species (Scolytinae) in Sweden is now 94.
