Other butterflies require that you make a spectacle of yourself like this Henry's Elfin. Elfins are small, mostly brown butterflies that one can easily lose track of on the ground. This requires that one stare intently at the spot one observed the butterfly go to ground. Alas, it is not immediately apparent to passersby that one is actually observing something thus generating odd looks...but I guess it does look odd to see a person stretched out on the ground staring intently at what appears from a distance to be nothing.
