The Orchid Awaiting an Insect 
Flowers are usually not only designed by their general 
shape to attract insects, but their nectar store is often sur- 
rounded by a target of some kind—sometimes of color only, and 
sometimes as in the case of the orchid, a folded leaf which guides the 
insect in. Almost all flowers, in this way, have centers which 
are white, or more brilliant than, or different from the 
rest of their color, as if to lead the insect to its 
work with the least possible delay. The 
orchid’s pollen may be seen in this 
photograph print direcily in the 
center of the flower.
