The Butterfly Alphabet is a photographic work done by the Norwegian naturalist Kjell Bloch Sandved. Sandved worked at the Smithsonian's National Museum of Natural History in Washington, D.C., and came up with the idea by chance, finding all 26 letters of the Latin alphabet and the Arabic numerals 0 to 9 in the patterns on the wings of butterflies.
His photographic excursions led him to Brazil, Congo, Papua New Guinea and Philippines. After searching for the forms for over 24 years, he finished in 1975 and published it in the Smithsonian Magazine. It was later published by Scholastic as a book in 1996, with accompanying snippets about butterfly species.
