Why do bugs take pollen?

insects are not looking for pollen : ) bees for example are looking for the nectar of a flower and the pollen gets stuck to their bodies, then when they go to another flower the pollen on their bodies sticks to the stomata of the flower (imagine that the pollen is the equivalent to male sperm and the stomata is the equivalent to a female genitals.) The pollen travels down the stomata to the ovum where it fertilises the seeds and they grow until they are ready to germinate : )
