Insects contribute to the pollination of flowers by transferring pollen from the male parts of a flower to the female parts of the same or another flower. This transfer of pollen is essential for the fertilization of plants and the production of seeds and fruits. Insects such as bees, butterflies, moths, beetles, and flies are common pollinators that visit flowers to feed on nectar and pollen, inadvertently carrying pollen from one flower to another as they move between them.
