A northernmost European record of the alien black soldier fly Hermetia illucens (Linnaeus, 1758) (Diptera: Stratiomyidae) / Nejsevernější evropský výskyt nepůvodní bráněnky Hermetia illucens (Linnaeus, 1758) (Diptera: Stratiomyidae)

The black soldier fly Hermetia illucens (Linnaeus, 1758) is recorded from Bohumín in Czech Silesia (Czech Republic). This finding represents not only the first record from the Czech Republic but also the northernmost occurrence (at 49°55'N) of this species in Europe. H. illucens is a non-indigenous fly in Europe that was introduced from the New World and is now distributed in the tropical and subtropical regions all over the world. The first Czech record is documented in detail and the causalities of the occurrence of H. illucens at so high a latitude is discussed. An updated distribution of the species in Europe is mapped.
