Entomophily or insect pollination is a form of pollination whereby pollen of plants, especially but not only of flowering plants, is distributed by insects. An interesting modification of flower shape for insect pollination occurs in some orchids in which a male insect mistakes the pattern on the orchid flower for the female species and tries to copulate with it, thereby pollinating the flower. 2. This phenomenon is called (1) Pseudo-pollination (2) Pseudo-parthenocarpy (3) Mimicry (4) Pseudo-copulation Sol. Anemophily is used by the flowers that are not scented and which do not produce nectar, whereas entomophily occurs in flowers that are scented and can produce nectar, to attract the insects.
