Entomophily refers to pollination by insects. In this type of pollination, flowers attract insects by providing them with rewards such as nectar or pollen. The insects, in turn, carry the pollen from one flower to another, facilitating the process of fertilization. The presence of attractants and rewards in entomophilous flowers is crucial for attracting and incentivizing insects to visit and pollinate them.

In certain species, floral rewards serve the purpose of providing a secure environment for egg-laying. One example of this is a relationship exists between a specific species of moth and the Yucca plant, where both organisms are interdependent for their life cycles. The moth lays its eggs in the ovary of the Yucca flower, facilitating pollination in the process. As the flower's seeds begin to develop, the moth larvae emerge from the eggs.
