Publicity has discovered butterflies as well. They are symbols of ecological harmlessness, lightness, airiness and cleanness. Even for the publicity of gasoline they are used to make it appear environmental friendly. They sit down on the clothes washed with a particular detergent. Printer-producing companies try to convince people of the quality of their printers by using colorful butterfly pictures.

As symbols of spring butterflies catch our eye in shop windows. A German department store even arranged a whole butterfly house inside the store for some time.
