Prinobius

Prinobius

*Prinobius* Mulsant, 1842 is among the most impressive cerambycids of the western Palaearctic, with adults reaching 25–60 mm in length and a notably robust, flattened body of dark brown coloration. Strictly nocturnal and strongly macropterous, adults are capable fliers and are reliably attracted to UV light during their flight season (June–September). Larvae develop deep within the heartwood and root system of ancient *Quercus*, requiring three to four years to complete development. The genus is listed under the EU Habitats Directive Annex II and is assessed as Near Threatened, reflecting ongoing declines linked to the loss of old-growth oak stands across the western Mediterranean.
