Locust
From Memory Alpha, the free Star Trek reference.
A locust is 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 harvest from locusts. (DS9: "If Wishes Were Horses")
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. (DS9: "Rapture")
- The locusts almost certainly represent the Dominion invading the Alpha Quadrant and heading for Cardassia later in the year.
