Flower that bloom at night

Since I'm young, I'm told that this particular flowers which looks like lotus will only bloom at night. It's been years growing this plant yet I have no idea what was the actual name for this type of flower.

It's been about 2 years since I saw the blooming of these flowers. In my memories, I used to see more than one flowers blooming. But this time round, there was only one flower.

I can't recall smelling any fragrance from this flower. Yet, by looking at the ants that crawled around the flower, you can feel how the sweetness and fragrance attracted these little "insects".

Although this flower looks beautiful, the lifespan was very short. It can only last for about 6-8 hours from the moment it started to bloom till withered.

If you do know the name of this flower, please drop me a note.
