First record of the invasive true bug (Heteroptera) Halyomorpha halys (Stål, 1855) from Hamburg with other records from Northern Germany and possible implications for its range expansion

The invasive pentatomid true bug Halyomorpha halys is reported for the first time from the German state of Hamburg, along with records from several other locations in Northern Germany. Specimens collected by scientists were evaluated along with records from citizen science platforms. DNA barcode sequences of several H. halys specimens from Hamburg were evaluated along with 42 sequences of the species from across the world in a haplotype network analysis demonstrating that all specimens studied from Hamburg had the haplotype H3. The present state of distribution of H. halys in Germany, patterns of range extension, invasiveness, and possible economic impacts are discussed.
