Xyleborus asper

Biology: 

Wood, 1982: This species breeds in the larger branches, limbs, and bole of a wide variety of hosts. Wood, 2007, general comment on Xyleborus spp.: Felled, broken, damaged, and unthrifty stems ranging in diameter from about 3 cm to more than 3 m are selected for attack. In broken or felled stems the attack may be massive and encompass most or all of the sapwood within a few days. The galleries are usually of a simple branching type that may join other similar galleries of the same species. Eggs are usually placed in clusters at or near the end of branch tunnels. The larvae feed on the mycelium of ambrosial fungi, then pupate in these galleries. The brood emerges from the parent entrance tunnels.
