Figure 46. Two views of a Calycopis cecrops on a leaf in southern Greenville County, South Carolina (17 August 2017), Alternating up and down movement of the tailed hind wings (arrows) is almost continuous when these lycaenid butterflies are resting on plants, leading salticids like P. pulcherrimus to attack the wrong end (Sourakov 2013). These butterflies are often found with damaged hind wings.
