Morphology
The compound combines 'army' (a large organized group) with 'worm' to denote worms that move in large numbers and attack crops; this meaning is a direct, describable extension of the constituent words. It follows regular English compounding patterns and a B1 learner who knows both constituents can reasonably infer it refers to a swarm-like pest even if they don't know the exact species.
Etymology
Army worm comes from the way these caterpillars move in long lines across fields, like an army of worms, eating crops as they go. That's why it means 'a caterpillar that moves in large groups and destroys crops'.
