common in tropical forests throughout South Asia to the far reaches of the Pacific Ocean
This usually has a transverse surface gallery between the bark and wood, part of which is expanded by the larvae into a brood chamber in which many of them develop. Further branching tunnels penetrate directly into the wood. These too develop brood chambers in the longitudinal plane. Brood development proceeds normally in the wood, if the tree is debarked. In some species (e.g. D. adusticollis(Motschulsky)), surface galleries and brood chambers have not been observed (Kalshoven 1959b, Browne 1961b).
