Hesperophanes

Hesperophanes

*Hesperophanes* Mulsant, 1839 is a medium to large longhorn beetle genus of the Mediterranean basin, with 12 species across the West Palaearctic and 2 species recorded from Europe. Adults are strongly nocturnal and are frequently attracted to ultraviolet light during the summer months, from June through September. The larvae develop in dead or dying wood of broadleaved trees and shrubs — including *Quercus*, *Olea*, *Arbutus*, *Pistacia*, and *Cistus* — requiring one to three years to complete development, and are capable of damaging structural timber. The genus is commonly known as the Western Longhorn, and adults have been observed feeding on pollen, bark, and sap.
