Some scales change greatly in appearance as they grow, and some species have males and females that differ in shape, size, and color. Adult males are rarely seen and are tiny, delicate, white to yellow insects with one pair of wings and a pair of long antennae. Some scale species lack males and the females reproduce without mating. The fig wax scale may be found on the stems, leaves, branches, and fruit of the host plants, which include a wide variety of plant families from all over the world. The adult females have an oval body with a thick grayish white wax covering tinged with red. This covering occurs in lateral plates with dry wax filaments protruding from the.

Some insects at your site may not be visiting transect plants – collect these labelled as ‘on the wing’ or collect a .
This catalogue of the Diaspidoidea of the world is based on the literature published (with few exceptions) up to the end of and includes for each species information on distribution and food-plants and a full bibliography of works on classification (including synonymy) and bionomics; bibliographies are also provided for each genus and higher by: Adult scale insects are usually covered in waxy shell-like cover. They feed by sucking sap from a wide range of plants, including house-plants, greenhouse plants and many fruit and ornamental plants grown outdoors. There are more than 25 species of scale insect in the UK. Some scale insects can weaken host plants and many excrete a sticky substance (honeydew) on foliage, which allows the.
Some soft scales may also have a hard covering present, but it will be smooth or with ridges, but no overlapping layers. Flip an adult scale over, and if there is a separate soft body beneath the hard shell, it is an armored scale.
