Morphology

red + spider

The meaning is directly built from 'red' (a color) + 'spider' (an arachnid), so a B1 learner who knows both words will infer it refers to a spider-like creature that is red; in context (gardening) they can reasonably identify it as a red pest. The compound follows a common and cross-linguistic color + noun pattern, making the referent predictable from its parts.

Etymology

Red spider may come from how these tiny, red mites make thin webs and look like little spiders on the underside of leaves. So the name refers to these small web-spinning creatures that 'damage' plants.
