Morphology

potato + bug

The noun-noun compound is compositional: a B1 learner who knows 'potato' and 'bug' will naturally interpret 'potato bug' as an insect associated with or found on potatoes (i.e., a bug that affects potato plants). Although it refers to a specific species, the relation is directly derivable from the constituents and follows common cross-linguistic compounding patterns, so the meaning is transparent.

Etymology

The noun potato bug comes from a simple picture: a small creature on a potato plant eating the leaves. Here potato shows the plant it likes and bug means 'insect', so the name tells you it is an insect that eats and damages potatoes.
