Do you know that Some moths never eat as adults because they do not have mouths. How do they survive?

Some moths never eat as adults because they do not have mouths. They have to live from the energy that's stored while they are caterpillars.
The adult wax moth has an acute sensory ability to find and use beeswax. It is easy to penetrate the bee hives to lay eggs, but usually the bees keep their numbers under control.
The adult wax moth has atrophied mouth, not feeding, and therefore does not cause damage, are the larvae, not the adult moths that eat wood, mostly, pollen and bee hive. Causing real damage inside the hive, with consequent economic losses for the beekeeper. Some moths never eat, and those that do, they drink the nectar.
