Damage
The damage occurs in the forest, the insects attacking standing trees and
freshly felled logs, tunneling into the wood for long distances
across the grain. No bore dust. Unlike most woodborers the adult does the
tunneling. Surface of tunnels are colored black/blue-black.
Holes vary in size depending on which of the Ambrosia beetles caused the damage;
many about the same size as furniture beetle holes.
Life cycle
Varies according to which species of Ambrosia beetle infested the log.
Notes
The damage is usually confused with Common Furniture Beetle damage but it occurs
in the log.
These insects cannot infest seasoned timber.
Quick Identification:
No bore dust; holes run across the grain long distances (pin test - c/f Common
Furniture Beetle).
Surface of tunnels colored black/blue-black. Since the damage occurred in the
log converted wood often cuts holes at an angle which makes them look elongated.
