Two New Butterfly Species Discovered
21 February 2014 11:30 am
In a rare discovery, researchers have come across two new butterfly species that appear quite similar but have incredibly different genes. After sequencing segments of the insects’ DNA and examining their genitalia, scientists found profound differences, including a variation in size and color of their external sex organs. A study published this month in ZooKeys details the two new species, Hermeuptychia intricata and Hermeuptychia hermybius, and supposes that they were long overlooked because of their resemblance to a butterfly identified two centuries ago—H. sosybius.
