Pollen grains to be carried by wind as well as by insects will not be heavy in weight or showy. This is because it causes the wind as well as insects tough to perform pollination. They prefer light weight as well as winged ones.

Wind pollinated plants will have light weight pollens which are mostly winged and are thus easy to be carried away by wind. Whereas the plants where the pollinating agents are insects, the petals will be bright and scented so that the insects get attracted to it and acts as pollinator.

A very close relationship between flower and pollinating agent is best exhibited by Yucca as there is a mutually rewarding relationship between Yucca plant and species of moth. They cannot complete their life cycle without each other. The moth lays egg in the locules of the ovary. The larva uses some of the seeds as food. In turn, the flowers are pollinated by the moth. 

Nectar is produced in saliva to lure pollinators such as insects and the process of pollination continues from one flower to the other flower and so on.
