Morphology
The phrase is fully compositional: 'aphid' names the insect, 'woolly' describes its appearance, and 'balsam' specifies its association with balsam (fir) trees, so a learner who knows the three words can infer it is a woolly aphid that affects balsam/fir. While a learner might not know the exact species name or the severity of infestation, the core referent is directly derivable and follows a common host+descriptor+noun pattern.
Etymology
Balsam woolly aphid comes from what the insect looks like and where it lives: it feeds on balsam fir trees, and the tiny aphid adults are covered in white, fuzzy wax that looks woolly, so the name links the insect's look and its tree. That's why it now means 'a small, wool-like insect that infests balsam firs'.
