Entomophily type of pollination takes place through the agency of insects. The entomophilous flowers are brightly coloured and fragrant to attract the insects. Their pollen grains are sticky or spiny to easily get attached to the body of pollinators. When the insects visit the flowers, their body gets dusted with pollen grains, and when they fly and visit other flowers, they brush against the stigma which being sticky, at once receives the pollen grains from their body. Thus, cross-pollination is achieved.
