Answer:
Bats and Sphinx moths
Explanation:
The cactus is a xerophytic plant which is mostly found in the desert and tropical areas of the world.
The cactus plants flower during the night time like Cereus which produce the white or pale white coloured flower. The flower produces a large amount of nectar as a gift and the fragrance to attract the pollinators.
The most attracted pollinators of the cactus plants which flies during night time are the long-nosed bats and the Sphinx moths which are similar to the hummingbirds and feed on the nectar with its beak-like structure.
Thus, Bats and Sphinx moths are correct.
