Habitat
It inhabits bushy, sunny or semi-shady, dry to moderate moist sites and supposedly has quite large minimum habitat requirements. Typical habitats are broad, sunny forest edges with Prunus-Ligustrum groves on slopes, bushy quarries, open woodlands with rich understory (with Vaccinium, Lonicera) or forest gap systems in mountain woodlands.
