Butterfly wing scale. Coloured scanning electron micrograph (SEM) of a scale from a butterfly wing. A butterfly wing is covered in many tiny scales. The scales are modified hairs,or setae,and are made of chitin,a common substance in insect exoskeletons. The iridescence of the colours of a butterfly's wings is produced by the diffraction of light by the microscopic ridges on these scales | |
