Description :
Richard Frey's worldwide Diptera collection. Ca. 10.000 species, including type material of some 700 taxa. Mostly material acquired by Frey, but some species have been added in the 1960s.
A preliminary catalogue of species/taxa names is available for this collection.
Data_quality: Largely identified by R. Frey himself. Most specimens have not been examined after Frey's death in the 1950s, thus the identifications are largely sensu circa 1920-1955.
