A male Ficus satterthwaitei fig growing in the grounds of the Crocker Range Park on the Kimanis to Keningau Road, in Sabah. Satterthwaitei  is a dioecious species i.e. separate male and female trees. From the  variety of insects  present it is obvious that this individual tree is male and can only produce male figs.

A black ant waiting for mature  fig wasps to emerge from the ostiole of the ripe fig. These predator ants protect the figs from parasitic  fig wasps but also  consume beneficial fig wasps. Overall however, studies have shown that their presence  is beneficial to  the fig tree and without their presence the fig crop would be destroyed by parasites.

Male figs only produce fig wasps and not seeds and are rarely eaten by animals, so the male figs usually rot on the tree. Here a moth larvae  is sucking juice from a rotting male fig.

The open ostiole indicates that the fig wasps that were incubated inside this male fig have left to pollinate a female fig tree. As no animals will eat the empty fig it begins to rot attracting a fly to the smell of decay.
Large numbers of rotting figs on the ground normally indicate a male tree.

As is typical with many fig trees, a new crop of figs is appearing even before the last crop reaches maturity. Thus although figs are produced in discrete crops  the gap between crops is reduced.

Around half a dozen Ficus satterthwaitei fig trees were  growing behind these visitor cabins at the Crocker Range Park HQ. in Dec. 2017.
