Wikipedia

From Middle English locuste, locust, from Anglo-Norman locuste, Middle French locuste, and their source, Latin locusta (“locust, crustacean, lobster”).^[1] Doublet of langouste.

The tree sense, originally referring to the carob (compare locust bean), is based on the resemblance of the trees' beanlike seed pods to the insect and is likely a semantic loan from Ancient Greek ἀκρίς (akrís).^[2]

The sense in "Mainlander" is a semantic loan from Cantonese 蝗蟲／蝗虫 (wong4 cung4), also meaning "locust".
