Yellow, red and orange ripe figs are one of the most important food sources in the rainforest.
The pollination process for figs is dependent on wasps. These wasps bore into the center of the unripe fruit of the fig tree, which is technically a flower. The wasps use the fruit/flower as a place to lay and germinate their eggs. In the process, they facilitate pollination of the fig tree. The eggs hatch with half of them resulting in males and the other half females. Eventually these wasps mate and the males drill a tunnel out so the females can leave. They then fly to the next fig tree, starting the cycle all over again.
Another fascinating oddity in Khao national park ecology is the strangler fig. While the strangler fig may look like a tree, it is actually a vine. When animals pass the seed and it falls on a host tree, it eventually sends fast-growing roots to the ground. After many years, these roots encircle the host tree. The host then dies and rots away, leaving a tunnel in the middle of the mature strangler fig.
