Colonization and geography of the Asian hornet
The Asian hornet has many subspecies. A black subspecies, Vespa Velutina Nigrithorax, was introduced into Europe before 2004 where it has become an invasive species. By April 2017, the hornet had already colonized most of France, Portugal, northern Spain and parts of Italy, Germany, Belgium and Great Britain.
