KOPSIA FLAVIDA
I recently saw the Common Birdwing visiting the flowers. Presumably, it is a nectar plant for its adult butterflies. Looking at the morphology of the flowers, it is not surprising considering that the flowers are single-petaled and have a tubed corolla.
But one can assume it is not a good nectar plant for most other smaller butterflies because I have never spotted them going anywhere near these flowers.
