Prionus

Prionus Geoffroy, 1762 is a genus of long-horned beetles of the subfamily Prioninae, tribe Prionini, widespread in Europe, Asia and North America.

Description


The members of this genus are large (25–70 mm) and usually brown or black.

All members of the genus Prionus have twelve or more strongly toothed or even flabellate antennomeres on their large antennae. The only species present in England is "the tanner", Prionus coriarius (Linnaeus, 1758).

Common North American species include the "tile-horned prionus", Prionus imbricornis, the "California root borer", Prionus californicus, and the "broad-necked root borer", Prionus laticollis.

Biology
The adults are nocturnal and are attracted to light, while their larvae feed on rotting wood or roots.
