graffiti for butterflies - elliott malkin

BLDGBLOG has a link to Graffiti for Butterflies, a project that uses sunscreen and paint to post signs on walls for migrating Monarch butterflies. It's certainly out there! Why not just plant more Milkweed? Well, he did that too. I wonder if the signs painted in sunscreen are recognisable to a butterfly. It should be pretty easy to set up a controlled test to see their effect. I hope the butterflies don't come to a sticky end. At least they won't get sunburnt.

Signs that say "No Dogs on the Velodrome" in dog language would be really handy. Painting the city's statues with "No Pigeons" in pigeon-visible text would be another good application for this idea. Maybe we could protect Australia's borders from alien species in a similar way. OK, now I am being silly. The butterfly idea was cute and well-meaning. I should not be facetious. I have no idea though how you could present useful data to a butterfly or just about any other species. Route info.? This is beyond the comprehension of most taxi drivers.
