Plants are known to smell, more and more. We had known for a long time that plant martingale was to protect itself from herbivorous animals: the plant that has been bitten releases the odor to warn neighboring plants, that they will knead the leaves and will not be of taste to the animal...
Like the plants among themselves, they also play with the animals in the plaza de dema de los olores. In America this has been investigated: on the leaves of some plants of the golden rod genus (Solidez virgaurea), fly males that wait for females and propagate a mixture of chemicals are put. The females come, lay the eggs and bite the stems of the plants. Some plants have been placed with that smell of the male and others without it and have measured where the female's eggs were. Where they didn't smell, there were four more eggs. The sting to put an egg is, of course, a wound, and as if it were not enough, the worms that are going to be produced will bite the plant before birth. The conclusion that has been drawn is that the plant perceives the smell of the males and prepares the protections to repel the stabbing attack of the female rule; these protections have measured that they also smoke beetles and other herbivores.
Some orchids are also known. The flower has all the shape of a female from a certain insect, and the male sits on it to cover it. Rubbing and rubbing will make a good pollination: give the pollen of the ruined flowers before and pick up the pollen of this flower to leave it in the flower of the next flowering. Some orchids have gone further. The flower mirror or orchid mirror (Ophrys speculum) is a nice example. The transfigured flower or petals painstakingly mimic the shoulder of the female Mediterranean bee Dasyscolia ciliata: when immobile it has a blue color with wings wrapped on the back; the hair around it resembles those of the bee's belly, and the upper petals are the same as the bee's antennas. Little, the orchid exhales the feromon that the female uses to attract the male. To introduce the stick, the fertilized flower exhales the same smell as the fertilized female bee uses to give peace. It was that bee that fascinated me!
