Biology:
Beaver and Browne, 1978: Associated only with Eugenia spp. (Myrtaceae). Gallery system similar to that of X. andrewesi. Browne, 1961: This species is the only Malayan ambrosia beetle that is known with certainty to have a fixed host relationship with the family Myrtacaceae and all records of it are from species of Eugenia. The observed hosts have been dying or cut trees, varying in diameter from about 3-15 cm. The nest is of the typical form of the genus with a more or less radial unbranched entrance tunnel and one terminal, large, oblong or subrectangular brood chamber in the longitudinal plane.
