A mustache on a butterfly has tipped off curators at the Natural History Museum in London that a specimen in their collection for 90 years actually belongs to a new species.
A curator found the disguised insect, initially collected from the dry Magdalena valleys of Colombia, among the 3 million butterfly specimens at the museum where it had lain undiscovered.
Blanca Huertas compared the mustachioed specimen with a recently found wild specimen, allowing her to identify the older specimen as Splendeuptychia ackeryi
, or Magdalena valley ringlet, whose distinguishing feature is unusually hairy mouthparts. (The name ackeryi
is dedicated to Phil Ackery, the former collection manager of the butterfly collections at the museum.)
