Stag beetles are a particularly impressive, even fearsome sight. The males of most species sport large, branching jaws that resemble antlers on a deer and give them their name. These jaws are used for fighting and wrestling with other males over territories and food. The females' mandibles are usually less showy and grand. There are around 1,200 species in this beetle family worldwide, with some species reaching a respectable 12cm in length. The larvae of the majority feed on rotting wood.

Stag beetle battle
Is a rotten old log really worth fighting over?
Stag beetles are Britain's largest beetles and are now rare in many of our woodlands. Here, two males fight over possesion of a rocky log, using their large mandibles for display and combat. The winner goes in search of a mate who has also been attracted by the log - it is here she will lay her eggs, so that the rotting wood can become an immediate food source for the grubs when they hatch.
