250_milkweed.jpgGraffiti for Butterflies has to be one of the most environmentally sound ideas for using the outlawed artform, even if it’s still just a concept. Designed to help direct “monarch butterflies to urban food sources along migratory routes in North America,” the project utilizes wall painted plant imagery to alert hungry tired butterflies:

“GFB uses images of milkweed flowers to broadcast the location of food sources to monarch butterflies. In the prototype at left, the graffiti is placed on a wall above an actual milkweed plant in New York City, signaling the presence of nectar to hungry monarchs in the vicinity.”

As the designer notes, it’s basically the “equivalent of a fast-food sign on a highway,” but for butterflies and placed in the city. |Dziga via Kottke|
