Rosalia
Rosalia longicorn, Alpine longhorn beetle
Rosalia is a genus of longhorn beetles (Cerambycidae) established by Audinet-Serville in 1833. The genus includes the iconic Rosalia alpina, known as the Rosalia longicorn or Alpine longhorn beetle, a large and strikingly colored species protected under the European Union Habitats Directive. Members of this genus are associated with beech forests and have experienced significant range contractions across Europe due to habitat loss and forest management practices. The genus is characterized by elongated bodies, long antennae, and often distinctive coloration including blue-gray tones with black spots.
