Morphology

beet + armyworm

The meaning is directly derivable from the parts: 'beet' names the host plant and 'armyworm' denotes a larval pest that moves in groups, so together they refer to an armyworm that attacks beets. This is a regular noun‑noun compounding pattern found cross‑linguistically and would be understandable to a B1 learner who knows both constituents.

Etymology

Beet armyworm is a name that gives a clear picture: beet shows what it eats and armyworm describes many caterpillars moving like an army across fields and eating leaves. That's why it means 'a small caterpillar that attacks beet and other vegetable crops and can cause serious damage'.
