Morphology

scale + insect

The compound is directly compositionally interpretable: 'scale' (a covering or plate) + 'insect' (small arthropod) yields an insect characterized by a scale-like protective covering. While the precise biological detail (sap-sucking, waxy secretion) is specialist knowledge, a B1 learner who knows both words will understand the basic meaning, and many languages form similar compounds, supporting transparency.

Etymology

Scale insect is named for the hard, flat scale-like covers that sit on these tiny insects and make them look like small bumps on leaves and stems. Because they 'suck' plant 'sap' and hide under this protective cover, scale insect now means those small, sap-sucking pests.
