This novel scale morphology likely helps to facilitate scale detachment through fluttering and, furthermore, increases wing transparency.Ĭonserved program fluttering pedicel scale development socket transparent moth wing. Fourth, the d-scale socket density is much lower than the a-scale socket density. Third, the socket on the wing surface into which the pedicel is inserted is much smaller for d-scales than a-scales. Second, the d-scale pedicel, which is the slender base of the scale, is tapered that of the a-scale is columnar. ![]() First, d-scales are much larger than a-scales. Although a-scales are morphologically common lepidopteran scales, d-scales have four distinctive features. This study showed that d-scale detachment only occurs through fluttering and that d-scales are obviously morphologically different from a-scales. To investigate the scale detachment mechanism, we analyzed the scale detachment process using video photography and examined the morphology of both d- and a-scales using optical and scanning electron microscopy. ![]() ![]() Even after this programmed detachment of scales (d-scales), small regions along the wing margin and vein still have scales attached (a-scales). However, in the pellucid hawk moth, Cephonodes hylas, numerous scales detach from a large region of the wing at initial take-off after eclosion consequently, a large transparent region without scales appears in the wing.
