This "weed", Bulbous Buttercup, has been appearing in my yard for years and I pull it up and it comes back and we have played this little game for a long time. Today I noticed that the topside of the petals had a metallic sheen! Yes, shining yellow petals to attract something wonderful. After about 40 minutes of searching I finally found the name on a great site enature, with a field guide for identification of all things wild.
