Host plants
polyphagous (Browne 1961bBrowne 1961b:
Browne FG. 1961b. The biology of Malayan Scolytidae and Platypodidae. Malayan Forest Records 22: 1-255.)
Remarks
The species attacks large logs, smaller stems down to about 3 cm diameter, and lianes (Browne 1961bBrowne 1961b:
Browne FG. 1961b. The biology of Malayan Scolytidae and Platypodidae. Malayan Forest Records 22: 1-255.). Beaver and Browne (1978) suggest that it may be particularly attracted to sappy stems.
