Csóka, György and Kovács, Tibor (1999): Xilofág rovarok - Xylophagous insects. Hungarian Forest Research Institute. Erdészeti Turományos Intézet, Agroinform Kiadó, Budapest, 189 pp. Mn: Szarvasbogár / En: Stag beetle The female is 25-50 mm, the male is 30-80 mm, rarely reaching 100 mm. European species, but rare in the north and west of Hungary, and already extinct in many places. The main foodplants are oaks, widespread and common in older forests. The larvae develop for 3-5 years in rotting roots, stumps and parts of trunk close to ground level. The beetles emerge in May-June, and during the day they rest on stems and branches feeding on fluids seeping from wounds on the tree. They swarm at sunset - particularly in hot and humid periods - and search for food and mate with a buzzing flight. The males die by the end of July, while females can survive until late August.
