Spot check: Dozens of very similar butterfly species from the Calisto genus are endemic in the Caribbean: left, C. hysius; right, C. obscura. Their taxonomy has been clarified with the help of DNA barcoding. (Photo: Andrei Sourakov.) Current Biology 2012 22, R73-R76DOI: (10.1016/j.cub.2012.01.036) Copyright © 2012 Terms and Conditions
