Pollen Transfer with Insects

Insects pollinate flowers by picking up pollen on their legs. The pollen is then carried by the animal directly from one plant to another. The insect does not do this intentionally. While it is eating, its legs brush against the pollen accidentally. The pollen is then rubbed off onto the stigma of the next flower it visits.

Pollen Transfer with Wind

Unlike insects, which carry the pollen between flowers, the wind blows pollen between plants to aid sexual reproduction. The pollen is carried in the air. Hay fever is an allergy to pollen in the air. More pollen is carried by wind than insects; it is a more random pollination process. Insects are able to move pollen directly between plants, whereas the wind changes and cannot direct pollen to exactly where it needs to land.
