SCALE See also:INSECT , a name given to See also:insects belonging to the See also:family Coccidae of the homopterous See also:division of the See also:Hemiptera and deriving their name from the formation by the See also:females of a waxy secretion which often hardens into a protective scale beneath which the insects live. See also:Honey-See also:dew, a sweet sticky substance is also secreted by some members of the family. The females are always wingless, but are provided with antennae, legs and well-See also:developed mouth-parts. In some cases these See also:organ. are retained, in some they are lost in the encysted See also:condition. The See also:males, on the contrary, although sometimes wingless, are, as a See also:rule, provided with a pair of large forewings and greatly reduced hindwings; their antennae and legs are longer than in the other See also:sex, but the mouth-parts are reduced and functionless (See ECONOMIC See also:ENTOMOLOGY).
