Moths of Germany (image) Consortium for the Barcode of Life (CBOL) Caption Completing regional inventories. For most applications, a regional barcode library answers the question "what organism is this?" Researchers recently completed a library that characterizes 1,264 of the 1,338 species (94 percent) of butterflies and large moths of Germany. Local agricultural pests and invasive species can now be identified by DNA and distinguished from non-harmful relatives. In Japan, botanists established a library of rbcL barcodes for 689 of the 783 local ferns and horsetails (94 percent), creating a naming tool that works for all life stages, including gametophyte forms often indistinguishable by appearance.
