During the workshop " Light and Shadow" I had the wonderful opportunity to get to know stag beetles a little closer. They live on old oaktrees and belong to the biggest beetles in Europe. They spend most of their life - 3-5 years - in the ground for the larval devlopment. After the beetles' hatch they live only for about 6 weeks  on the trees to reproduce. I was very lucky to witness a rival battle between 2 male beetles at the end of which the loser was being thrown off the tree.
