A DNA barcode library for 5,200 German flies and midges (Insecta: Diptera) and its implications for metabarcoding‐based biomonitoring

There are about 10,000 species of flies and midges in Germany. Based on 45,040 specimen of Diptera scientist from Bavarian State Collection of Zoology in Munich, from the Zoological Reseach Museum Alexander Koenig in Bonn and from the University of Guelph in Cananda, compiled a DNA barcode library for 5,200 species. Only a number of about 2,500 are named species. More than half of the barcodes could not be assigned to a species name: these are “Dark Taxa”.
