Insects and Flowers.- -Perhaps we are indebted to in- 

 sects for the bright colors and sweet honey of flowers. 

 Flowers need insects to carry their pollen to other flowers, 

 as cross-fertilization produces the best seeds. The insects 

 need the nectar of the flowers for food, and the bright 

 colors and sweet odors are the advertisements of the 

 flowers to attract insects. Flowers of brightest hues are 

 the ones that receive the visits of insects. Moths, butter- 

 flies, and bees carry most pollen (see Plant Biology, 

 Chap. VI).
