The gains to the pollinator have to do entirely with the question of food supply, apart from shelter and protection in the case of lodgers. The food may be nectar for the immediate use of the adult or for storage, or pollen for producing bee bread to feed the larvae.

Both may be gathered from the same species or each one from a different species, but the general effect in pollination is the same. In one-flowered plants, crossing alone can occur, and this is probably the rule with few-flowered ones. However, when the num- ber of flowers rises to hundreds and thousands, the manner of working by bees, butterflies, and hummingbirds in particular renders it prob- able that the great majority will be fertilized by the pollen of the plant that bears them. Furthermore, it is possible for certain sturdy.
