#721: Stag Beetle

The Stag Beetles are a group of over 1000 species of beetle, characterised by the large jaws of the male. Most commonly, however, the term refers to one species, the English Stag Beetle, Lucanus cervus. These large beetles require decaying wood, a habitat that is now threatened due to forest management (which removes older trees). The female lays her eggs in rotting wood, buried in soil, and the blind white larvae feed upon it. It takes 4-6 years, and several instars (developmental stages) before the larvae pupates. After three months, the Beetle hatches and flies unsteadily out into the world. His diet now consists of tree sap and nectar. He only lives a few weeks in this form, long enough to reproduce.
