Orchids, of the Orchidaceae family, are among the most diverse plants in the world, spread across all continents except Antarctica. In Italy there are over 100 species, most of them associated with prairie environments. The flower has an evident median petal called "labellum", which characterizes the different species. In the genus Ophrys the labellum imitates the abdomen of an insect to attract pollinating insects, which - in a vain attempt to mate - are covered with pollen, thus contributing to the fecundation processes. The small and light seeds are transported by the wind and are able to germinate in the soil, thanks to the intervention of a fungus, with which a symbiotic relationship is established (that is, a bond from which both organisms involved can benefit). In fact, the development of the embryo from the seed occurs through organic substances supplied by the fungus, which in turn obtains sugars from the plant, produced in the process of photosynthesis.
