Scientists have discovered a strangely patterned new insect in the Philippines, dubbing it the “pirate ant” because of a dark stripe over its eyes that makes it look like it’s wearing an eye patch.
The formal name of the newfound creature is Cardiocondyla pirata, and belongs to a group of species that are found from Thailand across the whole Indonesian-Malaysian region.
“On a collection trip to the Philippines we looked for different species of the genus Cardiocondyla that is known for its astonishing morphological and behavioral diversity of male ants,” Sabine Frohschammer, a doctoral student at Germany‘s Universitat Regensburg, said in a statement.
Frohschammer and colleagues picked up some already known species, but then found an unidentifiable one lurking between big stones in a shady streambed.
“Due to the darkness of the rain forest and the translucent body parts of the tiny ants they were nearly invisible,” the researchers said. “Under bright light and a magnifier we detected the nice stripe across the eyes and therefore always referred to these species as ‘the pirates.’”
The purpose of this ribbon of pigment on the mostly pigment-free pirate ants remains a mystery, the researchers say, especially since it has not been seen on any other creature of its kind. Pirate ants mate in the dark, and they have poor sight, relying mostly on chemical and tactile recognition cues, not visual ones, for communicating with other individuals in their species. That characteristic eliminates the possibility that the “eye patch” could serve as some sort of sexual signpost, the researchers say.
