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]
Scales play an important part in the natural history of Lepidoptera. Scales enable the development of vivid or indistinct patterns which help the organism protect itself by camouflage, mimicry, and warning. Besides providing insulation, dark patterns on wings allow sunlight to be absorbed and are probably involved in thermoregulation.
Scale insects are small insects of the order Hemiptera, suborder Sternorrhyncha. Of dramatically variable appearance and extreme sexual dimorphism , they comprise the infraorder Coccomorpha which is considered a more convenient grouping than the superfamily Coccoidea due to taxonomic uncertainties.
Chrysiridia rhipheus scale detail. Unlike in many other moths, the colour of C. rhipheus 's wings does not come from pigments. The colour originates from coherent scattering and interference of light by the microstructure of the ribbon-like scales covering the moth's wings.
Fiorinia theae, the tea scale, is a polyphagous scale insect which is native to Asia and has been introduced into the Americas. It is widely distributed on both continents, especially in warmer regions.
Kerriidae is a family of scale insects, commonly known as lac insects or lac scales. Some members of the genera Metatachardia , Tachardiella , Austrotacharidia , Afrotachardina , Tachardina , and Kerria are raised for commercial purposes, though the most commonly cultivated species is Kerria lacca .
Wax scale, Ceroplastes cirripediformis. The Coccidae are a family of scale insects belonging to the superfamily Coccoidea. They are commonly known as soft scales, wax scales or tortoise scales. The females are flat with elongated oval bodies and a smooth integument which may be covered with wax.
Eriococcidae are herbivores, like other scale insects. They occur on various hosts including trees, shrubs and grasses, and on most plant parts. [4] Many species produce galls, including Apiomorpha which feed on various species of eucalypt and have a complex life cycle. Species in this genus can produce separate male galls that are induced on ...
