Osmoderma
Typical Hermit Beetles, Hermit Beetles
Osmoderma is a genus of scarab beetles in the subfamily Cetoniinae, commonly known as hermit beetles. The genus has a Holarctic distribution, with species found across Europe, parts of Asia, and North America. Several European species, particularly O. eremita and O. barnabita, are of significant conservation concern due to habitat loss and are protected under the EU Habitats Directive. The genus is characterized by its dependence on tree hollows for larval development, making it highly vulnerable to forest management practices that remove dead wood and veteran trees.
