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.
