''Coccus viridis'' is a soft scale insect in the family Coccidae with a wide host range. It is commonly known as green scale or sometimes coffee green scale because it is a major pest of coffee crops throughout the world. ==Description== The adult scale insect is a glossy pale green colour with black internal markings that are visible through the chitinous body wall. It has a flattish elongated oval dome shape and is about three millimetres in width. The front end is rounded while the rear end has a distinctive groove. Adults retain their legs and antennae but mostly remain sedentary. The nymphs are a flattish oval shape, yellowish green, with six short legs. The nymphs shed their skin three times and each instar is larger and more convex than the previous one.〔Fredrick, J. M. 1943.
