DNA barcode reference library of bush-crickets (Orthoptera, Tettigoniidae) from the Iberian Peninsula.

Summary: Scientists are building a massive library, but instead of books, it holds the DNA of bush-crickets from Spain and Portugal! They collected DNA from 123 different types of these crickets, covering 85% of the species in the area. This "barcode" library helps researchers easily identify bugs in the wild. They found that 95% of the time, the DNA barcode works perfectly to identify the exact species. However, a few cricket species have mixed-up DNA from interbreeding, so scientists still need to be careful when reading those specific barcodes.
