Locust

Noun · /ˈləʊ.kəst/

Definition

A large migratory grasshopper that forms enormous destructive swarms. Also used figuratively for anything that devours resources rapidly in large numbers.

Origin

From Latin locusta, meaning lobster or locust — the Romans used the same word for both creatures, perhaps noting a physical resemblance. Entered Middle English via Old French locuste in the 14th century.
