acridophilous
An attraction to grasshoppers or locusts as a source of food.

Most of the locust's natural enemies; primarily, beetles, flies, and wasps are neither numerous enough on the ground nor mobile enough in the air to challenge vast swarms of locusts.

Birds regularly attack locusts, but their effect is only marginal. African kites drop from the sky and they barrel-roll through the swarm, grabbing locusts with snaps of their beaks, then they climb high to peel off again.
