Host plants

This species is also closely associated with Dipterocarpaceae (Browne 1961bBrowne 1961b:
Browne FG. 1961b. The biology of Malayan Scolytidae and Platypodidae. Malayan Forest Records 22: 1-255.
). There are records of single specimens taken from three other families (Ohno 1990Ohno 1990:
Ohno S. 1990. The Scolytidae and Platypodidae (Coleoptera) from Borneo found in logs at Nagoya port 1. Research Bulletin of the Plant Protection Service, Japan 26: 83-94.
), but they may not have been breeding.
