Doleschall's Cross Spider- Argiope doleschalli ♀
Argiope spiders, especially large ones like this, will drop from its web onto the foliage or ground below at the slightest of disturbance.
Its amazing how far they can drop (even when hitting hard surface) without hurting themselves, equivalent to humans jumping down from a 2 storey or higher building (without dying of course XD)!
The spider is pretty smart, releasing a silk-thread (Note the thin line at the back of its abdomen) as it drops so that it can easily get back to its web after the potential threat is gone.
