Variation in cross rib morphology. (a–d) Male L. nitida (Satyrinae: Nymphalidae). (a) Dorsal view. (b) Effect of illuminating and observing the DHW anteroposteriorly. (c) The same region of the hindwing displaying violet structural colour when illuminated and observed posteroanteriorly. (d) SEM of the cover scale from the DHW, indicating the position of the flutes (Fl) and cross ribs (Cr). (e–g) Male E. tricolor (Satyrinae: Nymphalidae). (e) Dorsal view. (f) SEM of a scale from the region indicated by arrow in (e), showing the cross rib plates (CR) connected by nodules (N). (g) Transverse SEM of the same scale, showing a stack (ST) formed by adjacent cross ribs. (h–k) SEMs of the cover scales from the DHWs of papilionids (Papilioninae: Papilionidae; regions in brackets). (h) Graphium kirbyi (brown). (i) Graphium illyris (brown). (j) Lamproptera meges ennuis (black). (k) Papilio phorcas (brown).
