Morphology

bean + beetle

The compound 'bean beetle' is directly compositional: combining 'bean' (the plant/seed) with 'beetle' (an insect) yields an insect associated with bean plants. This host+insect naming pattern is common and predictable cross-linguistically, so a B1 learner who knows both constituents will readily infer the intended meaning.

Etymology

Bean beetle comes from a small beetle that eats the leaves of bean plants, so farmers call it a 'pest' when it harms their crops.
