Lyctus africanus

Lyctus africanus, the African powderpost beetle, is a species of powder-post beetle in the family Bostrichidae. It is found in Africa, Europe and Northern Asia (excluding China), North America, and Southern Asia. The mature insects are characterized by their reddish-brown coloration and small size, ranging from 3 to 5 mm. Infestations are generally detected through the activity of the larvae, which excavate hardwood sapwood to extract dietary starch, afterward generating a fine, powdery frass. L. africanus poses a severe economic risk to hardwood products, including timber, plywood, and furniture. It inflicts widespread, gradual damage that frequently goes unnoticed until the wood's structural integrity is already severely compromised.
