'Fly' in the Bible

He gave the word, and there came the dog-fly, and insects over all the land.

And it will be in that day that the Lord will make a piping sound for the fly which is in the end of the rivers of Egypt, and for the bee which is in the land of Assyria.

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.
