'Worm' in the Bible

What the worm did not make a meal of, has been taken by the locust; and what the locust did not take, has been food for the plant-worm; and what the plant-worm did not take, has been food for the field-fly.

I will give back to you the years which were food for the locust, the plant-worm, the field-fly, and the worm, my great army which I sent among you.
