Thanks to your clues, smart observations and comments on my previous post "UFO on UFO", the flower and the bug has been identified.
The flower is Bauhinia acuminata while the bug is Amata huebneri. Both the flower and the bug are natives here.
The flowers of the Bauhinia acuminata is about 3 inches in diameter. Each flower has 5 petals which are a bright white in colour. When in bloom, they look like snowflakes on the branches and they also exude a nice fragrance with a hint of the scent of roses. You can use them as cut flowers.
The leaves are shaped like ox-hooves.

The plant can reach a height of about 8-9 ft when grown on the ground and shorter if planted in containers. The requirements are good soil drainage, regular watering, occassional fertilizing and full to partial sun exposure. It is suitable for USDA 9b - 11. It blooms best when under stress!
Amata huebneri is a day-flying moth that mimics the stinging wasps as a camourflage from predator birds. They are actually quite harmless. They belong to Arctiidae, a family of wooly bears or tiger moths. Their larvae feed on rice in the paddy fields.
