Figure 6. Scaling of Cheimas opalinus. (a) C. opalinus opalinus female hind wing dorsal surface showing the edge of the structural colour patch; the folded apices of the colour-generating scales are well visible, as well as the flat ordinary scales with brown coloration; (b) female ventral hind wing surface discal area showing that there are no hairs; (c) male ventral hind wing discal area showing dense hairiness; (d) lateral view of the male wing membrane showing the short hairs more or less perpendicular to the ventral wing surface (upper surface) and the longer hairs of the wing dorsal surface (lower surface) (scale, 1 mm).
