Butterfly wing. Coloured scanning electron micrograph (SEM) of scales on a small blue butterfly (Cupido minimus) 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 structure of these scales. Magnification: x200 when printed at 10 centimetres wide | |
