European stag beetle, is one of the largest beetle found in Europe

Lucanus cervus, the European stag beetle, is one of the best-known species of stag beetle (family Lucanidae) in Western Europe. Now there is a widespread decline in the number of stag beetle, which is almost universally low and continues to decline. Stag beetles are rare and local, but mostly in large numbers. Despite this, the range of the species is declining, and in the near future it may be threatened with extinction.
