Locust
A locust was an insect from Earth, known for its destructive impact on agriculture. 

In 2369, Rumpelstiltskin told Miles O'Brien a story about a farmer from Derry who had tried to chase him away before he saved the farmer's crop from locusts. ()

In a vision experienced by Benjamin Sisko in 2373, he saw a swarm of locusts appear in the sky above Bajor before traveling to Cardassia Prime. () These "locusts" later turned out to be the Dominion fleet that arrived after the Cardassian Union joined. ()
