Morphology

flour + beetle

The compound 'flour beetle' is transparently compositional: 'flour' modifies 'beetle' to indicate a beetle associated with or found in flour (habitat/diet), so a B1 learner who knows both words can readily infer it is a small pest that infests flour or stored grains. Noun–noun modification of this kind is a common, cross-linguistic pattern and therefore predictable.

Etymology

Flour beetle is a small insect named for where it lives: flour and the beetle that hides in it. These tiny creatures hide in stored grain and spoil food, so the name now means a pantry 'pest'.
