'Insects' in the Bible

For if you do not let My people go, behold, I will send swarms of flies on you and on your servants and on your people and into your houses; and the houses of the Egyptians will be full of swarms of flies, and also the ground on which they dwell.

But on that day I will set apart the land of Goshen, where My people are living, so that no swarms of flies will be there, in order that you may know that I, the Lord, am in the midst of the land.

Then the Lord did so. And there came great swarms of flies into the house of Pharaoh and the houses of his servants and the land was laid waste because of the swarms of flies in all the land of Egypt.

Then Moses said, “Behold, I am going out from you, and I shall make supplication to the Lord that the swarms of flies may depart from Pharaoh, from his servants, and from his people tomorrow; only do not let Pharaoh deal deceitfully again in not letting the people go to sacrifice to the Lord.”

The Lord did as Moses asked, and removed the swarms of flies from Pharaoh, from his servants and from his people; not one remained.
