Butterflies come from Caterpillars

OH, how beautiful! Oh, my goodness, how beautiful they are! There are some whose wings are barred with red on a garnet background; some bright blue with black circles; others are sulphur-yellow with orange spots; again others are white fringed with gold-color. They have on the forehead two fine horns, two antennæ, sometimes fringed like an aigrette, sometimes cut off like a tuft of feathers. Under the head they have a proboscis, a sucker as fine as a hair and twisted into a spiral. When they approach a flower, they untwist the proboscis and plunge it to the bottom of the corolla to drink a drop of honeyed liquor. Oh, how beautiful they are! Oh, my goodness, how beautiful they are! But if one manages to touch them, their wings tarnish and leave between the fingers a fine dust like that of precious metals.
