You might find this article interesting which someone previously posted a link to here. It talks about how orchids are designed to 'trick' insects, either trick then into thinking the flower is offering food, or to trick it into thinking the flower is offering sex. Really ineteresting article. Orchids — National Geographic Magazine
I find the roots the most interesting, one because you have them all year round, and the fact they don't really need soil.
Really look at the Vandas, the shape the twists the turns, they overlap, they have many eyes, just fantastic. Study the roots on mounted orchids.
The flowers are beautiful, but as you look at them, your eye is drawn to the lip, just as God layed out a road map for the intended pollinating bee to follow.
