Beaver and Browne, 1978: A spanandrous ambrosia beetle now recorded from 13 families of trees, and showing no obvious host preference. In Penang, stems from 3-5.5 cm diameter were attacked. The gallery system has a short radial tunnel which divides into several branches but does not penetrate deeply into the wood. Browne, 1961: There is no indication of host preference for this species. It usually infests branches and small poles, down to a minimum diameter of 3 cm of cut, dying or dead trees, but it will also attack dead logs. Before entering the wood of the host the female will sometimes gnaw out a very small cavity beneath the bark to offer shelter as she begins construction of the main part of the nest.The entrance tunnel penetrates radially for a short distance and then breaks up into several branches in various planes. Hulcr and Cognato, 2012: Short tunnels branching randomly into xylem, mostly in small branches.
