Answer by  AJN (39)

Moths are very similar to butterflies. They will feed off nectar or fruit juices. Water is the only requirement for most moths. At this stage in a butterfly or moths life mating is of the only concern as they are on borrowed time in their life. Some moths will not feed at all once they have reached adulthood.

It isn't the moths that eat, it is their larvae, or caterpillars. They commonly eat vegetation. Some specialize in eating tree leaves, like gypsy moth larvae, some eat tomato plants, like the tomato hornworm. Others eat other vegetation. The carpenter worm eats wood.
