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. Adult females typically have soft bodies and no ...
Ants – social insects with geniculate (elbowed) antennae and a distinctive node-like structure that forms a slender waist. Ants are of the family Formicidae and evolved from wasp-like ancestors in the mid-Cretaceous period between 110 and 130 million years ago, diversifying after the rise of flowering plants.
The scale insect Dactylopius coccus produces the brilliant red-coloured carminic acid to deter predators. Up to 100,000 scale insects need to be collected and processed to make a kilogram (2.2 lbs) of cochineal dye. [89] A similar number of lac bugs are needed to make a kilogram of shellac, a brush-on colourant and wood finish. [90]

An ant collects honeydew from an aphid Ants collecting honeydew from Calico scales (Eulecanium cerasorum) then played at 30 times speed to show the pumping action of the scale. Aphids and other hemipteran insects secrete a sweet liquid called honeydew , when they feed on plant sap .
