Male Mocker At Rest (image) University of Exeter Caption The African Swallowtail butterfly, also known as the 'Mocker Swallowtail' or the 'Flying Handkerchief,' can appear to change both colour and shape. Males of the species fly boldly around the tree tops, their rapid flight making them look like shaking handkerchiefs, however females lurk in the bushes and pretend to be examples of Monarch butterflies that are nasty to eat.
