Morphology
The compound 'flea beetle' is compositionally transparent: it denotes a beetle with a flea-like quality (notably the ability to jump). A B1 learner who knows 'flea' and 'beetle' can readily infer that it refers to a small beetle that jumps like a flea, following common noun-compound patterns.
Etymology
The name flea beetle comes from the insect's tiny size and strong back legs that let the beetle jump like a flea, so people put the two words together. That's why 'flea beetle' means a small leaf beetle that jumps and often damages plants.
