Name Story

Lucanus cervus

means “the stag of Lucania”

What does its name mean?
  • Lucanus — from Lucania, a region of southern Italy, where children once wore these beetles as lucky charmsLatin (recorded by Pliny)
  • cervus — stag, deerLatin, for the male's antler-like jaws

The male stag beetle wears a huge pair of jaws like a deer's antlers, which he uses to wrestle rival males — so 'cervus', meaning 'stag', fits beautifully. It is Britain's biggest land beetle, and the Romans gave it its name long ago.
