Caption
Changes in nanosphere size during ontogeny. (A) Cryo-SEM micrograph of a damselfly tail showing a cross-section through the epidermis. Yellow arrowheads; direction of incident light. (B) Box chart showing the sizes of nanospheres extracted from individuals with different thorax colors as well as tails. The average diameter and the SD measured in each specimen (nm) is displayed on the chart. (C) Cryo-SEM images of pteridine nanospheres in the distal epidermis in thoraxes (i–iv) and a tail (v). The colors of the box chart in (B) and panel bars in (C) are the CIE representation of the reflectance measured from the specific tail/thorax analyzed.
