Explanation:

This describes a coevolutionary adaptation where the moth's long tongue matches the orchid's long nectar spur. The key advantage is accessing a food source unavailable to shorter-tongued pollinators, giving the moth exclusive access to the orchid's nectar.

It can reach nectar that no other pollinator can reach.
