European Stag Beetle

Fascinating facts about the European Stag Beetle

• The European stag beetle is the largest beetle in Europe, making it instantly recognisable wherever it appears. Males can reach up to 7.5 centimetres in length while females are smaller, ranging from 3 to 5 centimetres. Its usual black colour is highlighted by reddish wing covers and the male's striking red mandibles. The species is sexually dimorphic, with males bearing the enlarged mandibles that give the beetle its name.
• Adults emerge from late May to early August and are most active during the evenings, feeding on nectar, fallen fruit and tree sap. The beetle spends the bulk of its life hidden as a larva, requiring three to seven years to develop before pupating. Once it reaches adulthood, the beetle lives only a few weeks, a brief period dedicated to mating and dispersal. This short adult phase contrasts sharply with the lengthy larval stage.
• The larvae possess comb-like structures on their legs which they use to produce stridulatory sounds that allow them to communicate with other larvae underground. These blind, C-shaped youngsters feed on rotting wood found in tree stumps, old trees, decaying fence posts, compost heaps and leaf mould, living deep within the soil. Their development is slow, taking several years and passing through multiple instars before they finally pupate.
