Mass flowering was observed at the Kabili-Sepilok Forest Reserve, Sabah from early to mid 2010, which provided an opportunity to study the insect florivores of the dipterocarp flowers. Twelve host dipterocarp species were investigated in this study, half of which were endemic to Borneo. Larvae of 20 lepidopteran species were documented feeding on the flowers. All are new records as there are few past studies on florivory in the dipterocarp canopy. The most frequently encountered species was Etanna breviuscula Walker (Lepidoptera: Nolidae), which was recorded from five dipterocarp species, followed by Dudua aprobola Meyrick (Lepidoptera: Tortricidae) and Mesotrophe intortaria Guenée (Lepidoptera: Geometridae). A few insect predators of the flower feeders were also observed.
