The butterfly is of great economic importance because it plays a vital role in the pollination of flowers of crops and other plants. Butterflies have long, slender tongues that can reach deep into flowers to suck nectar. In the process of collecting nectar, the butterfly transfers pollen from the male flower part (stamen) to the female flower part (pistil) of the same or different flowers, resulting in fertilization and fruit or seed production. This makes butterflies important pollinators that contribute to the growth and productivity of many plant species, including those that are economically important to humans.
