Rosalia alpina is a large, rare and beautiful beetle, protected throughout Europe and threatened by intense forest management. It has become a flagship species for nature protection in beech forests. In lack of dead, large sized beech trunks in managed forests the females are induced to oviposit on beech firewood. The larvae need 3 to 4 years for their development, so most of them end up in an oven or chimney before they can emerge as adult beetles. Choice experiments in Switzerland have shown that the females prefer thick, long, standing beech trunks for oviposition. We therefore recommend to place such a dead trunk besides beech firewood piles in areas where Rosalia had been seen to save at least part of their offspring.
