For example,in 1875 one biologist pointed out the diversity of butterflies in the Amazon when
he mentioned that about 700 species were found within an hour's walk,whereas the total
(10) number found on the British islands did not exceed 66,and the whole of Europe supported only 321.This early comparison of tropical and temperate butterfly richness has been well confirmed.
