The article documented Larus gulls feeding on the moth Crambus perlella in a hay field.

The unknown caterpillar sent off in a LifeScanner vial was subsequently identified as Crambus perlella from its DNA.

Building a DNA barcode library of Alaska’s nonmarine arthropods

The early version of this article in the journal Genome appeared in October 2016, but the final version was posted more recently.  Almost half (48.5%) of the known 8,277 Alaskan, non-marine-arthropod species now have associated DNA barcodes, enabling species identifications by DNA barcoding.
