The Two-barred Flasher (Astraptes fulgerator), is a cryptic species complex in the spread-wing skipper butterfly genus Astraptes. It ranges all over the Americas, from the southern USA to northern Argentina. A. fulgerator's adults all look quite alike. They are mid-sized skipper butterflies with the typical wing shape of this group. The upperside is black, with basal to postbasal blue corners which are more extensive on the forewings. There is one discal-tomal and one apical band on the forewing; these are usually off-white to light blue but the former may be quite white towards the costal margin. The thorax has bluish hair on the back, the underside is yellow to orange.The caterpillars and pupae show a wide range of colors and patterns, and the caterpillars also vary in food preference. Last-instar caterpillars are black with a pattern consisting of light to bright yellow dots along the sides, or rings of varying thickness, sometimes interrupted on the back, in a range of colors varying from white to orange-red.
