The finding of fragments of Osmoderma eremita (Coleoptera, Scarabaeidae, Cetoniinae) in September 2009, at the base of an oak (Quercus robur) in Geneva's countryside, suggests that this beetle of national importance still occurs in the canton of Geneva. The survival of this species relies on the availability of old hollow trees. These have largely disappeared with the intensification of land use and the changes in sylvopastoral practices. The creation and tending of hedge networks hosting large old trees would allow not only to preserve an emblematic species, but also the witnesses of ancient practices and cultural heritage.
