A round, shield-like structure or plate found in anatomy, particularly the flattened anterior portion of an insect's head between the compound eyes.
From Latin 'clipeus' meaning shield. Naturalists in the 18th century applied this classical term to insect anatomy because of the resemblance of certain structures to Roman shields.
Ancient Romans fought with clipei (shields), and 300 years later naturalists borrowed the exact same word to describe the mysterious plates on insect faces—it's like they were saying 'this bug has tiny Roman armor on its head!'
