Answer - A nocturnal pollinator

The comet orchid is most likely pollinated by a nocturnal pollinator because of the nightly aromatic scent emitted by its nectar. This makes it possible for a nocturnal pollinator to detect, visit and pollinate it at night. The lack of scent during daylight hours makes it unlikely for a diurnal pollinator to visit it.
