Bálint, Zs.: Lepidoptera collections of historical importance in the Hungarian Natural History Museum

FRIVALDSZKY strived to have a collection as complete as possible. Therefore he was corresponding very widely. According to his autobiography and letters he was in exchange or mercantile connection with more than a hundred naturalists of his time (BÁLINT & FRIVALDSZKY 2007). Consequently amongst the specimens of the FRIVALDSZKY collection there is a high possibility to find syntypic material of other authors, notable the ones whom FRIVALDSZKY exchanged or corresponded.
