White Antenna Wasp Moth

Thank you Bayucca. Its the first Moth picture I ever taken. Not sure about details. I would name it as A.nigriceps as per https://www.flickr.com/photos/diazseptsi.... It is found in my country.

Amata trigonophora is to my knowledge not found in Singapore and there are many other Amata sp. around and many are not IDed or not correctly IDed. Yours looks very similar to Amata huebneri, but the head looks somehow different. Yours has a black head with an orange ring behind the eyes and a yellow front. Personally I would go with Amata sp. as scientific name.
Same one like yours in my eyes:

Could be yours but ID correct (Wiki is not really trustable without triple counterproof):

Amata huebneri, note different head colors:

Trigonophora to compare, spots are too small in yours:
