On the Green continent there an unusual type of orchid flowers with about two centimeters, which is very reminiscent of the shape of a flying duck. Nature does nothing in vain, and here, too, there is an explanation.
It is for this type of orchid person resembles a flying duck. For insects, which are called sawflies, the upper part of the flower resembles the female of this sawfly and attracts males. No, they do not eat the orchid. It simply uses the male as transporters of pollen from one flower to another part, for pollination. Male for some time, falls into the trap of the flower and uniquely covered with pollen. Attempts to pull with a "flower clone" of the female, the male himself without realizing it, delivers the stigma of orchid pollen so necessary.
