About the Ant
Location: Papua New Guinea
With their spiny backs reminding scientists of a dragon, this new species of ant is named for Drogon, the fierce black dragon commanded by Daenerys Targaryen in the epic fantasy, Game of Thrones. Pheidole drogon is one of two new species of spiny ants from Papua New Guinea.
Previously, large back spines were assumed to be a defense mechanism. However, microtomography — similar to medical CT scans — suggests at least some of the spines serve as a location for muscle attachment. Major workers, or soldiers, have exceptionally large heads and mandibles used to crush seeds otherwise inedible to them. Large heads require large muscles that must be anchored somewhere, such as the spines. However, spines occur also in minor workers, with smaller heads, and not all spines are host to muscle attachment.
