Insect scale information


Wing scales form the colour and pattern on wings. The scales shown here are lamellar. The pedicel can be seen attached to a few loose scales.

Scales are present on the bodies of various insects. A notable example are the Lepidoptera, the insect order comprising moths and butterflies, which have scales on their wings and on the head, parts of the thorax and abdomen, and parts of the genitalia. The name is derived from Ancient Greek λεπίδος (scale) and πτερόν (wing).[1]

The Trichoptera (caddisflies) which are a sister group of the Lepidoptera have scales, but also possess caudal cerci on the abdomen, a feature absent in the Lepidoptera.[2] Beetles of family Dermestidae also commonly have scales.[3]
