Lucanus cervus (Lucanus cervus) is the biggest beatle of Europe. It is an endangered species which is protected by The Berne Convention on the Conservation of European Wildlife and Natural Habitats. Adult males, unlike females, are larger and have much larger mandibles (sexual dimorphism). Its typical habitat are broad-leaved trees (mainly oak) and dead trunks. The pictures below shows the beatle, which we have found during summer season 2011 in Hrušovany nad Jevišovkou town.
