as indicated for this contest, a lucky photographer will get two in one:
a beautiful butterfly and a beautiful flower: you can see the pollen loaded "tail" of the butterfly pollinating the pistils;
the butterfly is Papilio dardanus: Papilio dardanus, the African swallowtail, mocker swallowtail or flying handkerchief, is a species of butterfly in the family Papilionidae (the swallowtails). The species is broadly distributed throughout Sub-Saharan Africa. The British entomologist E. B. Poulton described it as "the most interesting butterfly in the world".
