Some species have certain habitat requirements; some Ortheziidae occur in damp meadows, among mosses and in woodland soil, and the boreal ensign scale (Newsteadia floccosa) inhabits plant litter. The Coccomorpha are division into two clades the "Archaeococcoids" and "Neococcoids". (2 Pages). Insect damage to humans and livestock also may be direct or indirect.

With over 8,000 species and sub-species, it can be difficult to explain exactly what scale insects are. While some specialise on a single plant species (monophagous), and some on a single genus or plant family (oligophagous), others are less specialised and feed on several plant groups (polyphagous). I have a monkey grass problem. While most thrips are known to feed on fungi and plants, studies have confirmed that thrips have 'piercing-sucking' mouthparts that can bite people. [16] Fungi in the genus Septobasidium have a more complex, mutualistic relationship with scale insects. Many scales produce crawlers in the spring. Tea scale insects appear as a slightly fuzzy white and brown coating on the underside of the leaves. A cladogram showing the major families using this methodology is shown below.
