Switzerland. Canton Zürich. Winterthur. An old man half asleep sits alone on a chair in a shopping center. Plastic fake butterflies are hanged from the ceiling and used as decorations. Butterflies are insects in the macrolepidopteran clade Rhopalocera from the order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. © 1990 Didier Ruef
