Morphology

army + ant

The meaning 'a nomadic ant that moves in large groups' is directly derivable from combining 'army' (a large organized group) with 'ant' (the insect): the compound describes ants that behave like an army. This is a productive, compositional noun compound pattern found across languages, so a B1 learner who knows both words would very likely infer the MWE's meaning.

Etymology

Army ant comes from the simple image of these ants moving like an army, in long, fast lines that hunt other insects, pushing prey out of hiding. So, army ant now means a kind of ant that 'moves in large groups to hunt'.
