Coleoptera, Lucanidae , Baltic Sea region, fauna. The area of investigations. Countries of Western and Northern Europe such as DK, D, FI, S, N have a natural environment which has been largely destroyed by the long and intensive human economic activities. In these countries there are remnants of biotopes that have not altered greatly from their natural state, and most of them have now been designated as protected areas. In these countries the situation regarding primary biotopes is not so problematical as in Western Europe.
Stag beetles develop in the rotten wood of fallen or old trees.
Because of this close connection with old and dead trees, Lucanidae occur in old forests and parks. There are not problems to identified imago of all species of the Baltic Sea region. But it is not so easy to identified larvae. I include figures of terminal segments of some Lucanidae species from our region - Fig.2.
