Lucanus cervus (Linnaeus, 1758) |
|
Lucanus cervus is the best-known species of stag beetle (family Lucanidae) in Western Europe, and is the eponymous example of the genus. L. cervus is listed as Near Threatened by the IUCN Red List.
L. cervus includes two subspecies: L. c. cervus (males: 35–92 mm, females: 35–45 mm; ) and L. c. judaicus (males: 50–100 mm, females: 40–50 mm)
Sexually dimorphic, the males have enlarged mandibles and are larger than the females. Although the male's mandibles seem threatening, they are too weak to be harmful. Nevertheless, females can inflict a painful bite. The resemblance of the male's mandibles to the horns of a stag, and their use in combat between males, much like with deer, gives the species its scientific and common names.
Adult size varies between different areas of its distribution, for example beetles from Spain, Germany, and the Netherlands are larger than those from Belgium or the UK.
L. cervus is widespread across Europe, though it is absent from Ireland. In Germany it is widespread, mainly in the south.In Hungary this species is widespread in the hilly and mountainous areas. In Romania it is widespread, especially in the hilly areas with sun exposed slopes. It also occurs in the European part of Turkey. In Italy it is mainly distributed in northern and central regions. In Spain and Portugal it is present only in the northern half of each country. In Britain it is largely confined to the south-east of England, where it is widespread. This species is now extinct in Denmark and Latvia. It is also found in Caucasus, Asia Minor, Syria and west Kazakhstan. Its range is currently only increasing in Croatia and Slovakia.
L. cervus has been associated with a range of trees including those in the families Oak (Quercus), Lime (Tilia), Beech (Fagus), Willow (Salix) and specific species from other families including Black poplar (Populus nigra), Ash (Fraxinus excelsior), Horse-chestnut (Aesculus hippocastanum), wild cherry (Prunus avium), and Common walnut (Juglans regia).
