Stenurella

Stenurella

*Stenurella* Villiers, 1974 are small to medium-sized longhorn beetles (6–16 mm) with a distinctively tapering body, typically black or bicolored with reddish elytra and a darkened apex. With four species in Europe and 15 across the West Palaearctic, the genus is widespread from lowlands to elevations of around 1500 m. Adults are conspicuous and abundant flower visitors, particularly on Apiaceae and Rosaceae, flying strongly by day from May through August. Larvae develop in decaying, often moist wood of deciduous and coniferous trees, frequently in smaller-diameter stems and roots in contact with the soil, with development spanning two to four years.
