A male Ficus lumutana fruiting next to the steps just below the Belalong Canopy Walkway, Temburong, Brunei on 14 December 2017. The same fig tree was photographed fruiting almost exactly a year earlier on 18 December 2016. We do not know if there were any additional fruiting episodes in between Dec. 2016 and Dec. 2017.

Female Ficus lumutana fruiting at Danum Valley Field Center. Note that ripe male and female figs look totally different.

Ficus lumutana is one of only a few figs in Borneo in which the  male figs split wide open at the base to allow the female fig wasps to leave the fig without damaging their wings.

In December 2016 there was much evidence of ants  excavating holes in the bark of the trunk but the damage was fairly minor. A year later the damage is much more severe with the wooden trunk exposed below the bark. The ants appear to be excavating gaps under the bark for use as secure housing or domatia.
