Branch and Twig Borer

Amphicerus sp., Branch and Twig Borer photo

Family: Bostrichidae

Subfamily: Bostrichinae

Length: 5-15 mm


Members of the genus Amphicerus have a pronotum that seems almost spherical when viewed from above. The pronotum hides the head.

These small beetles can become major pests for foresters, weakening trees by their feeding, and disfiguring the lumber with their tunneling.

The beetle pictured here measured 5.9 mm and lacks the forward-pointing pronotal teeth present in some other species of Amphicerus.
