“He sent swarms of flies among them, which devoured them. . .” Psalm 78:45 (NKJV)
The Eastern Washington prairie in autumn is beautiful for its colors and still mild weather, with alternating rain and sunshine. A less likeable fall feature is the gnats. They swarm, tiny specks of face-level (no matter how tall you are) white flies. They turn black when scrunched, as I tend to think they deserve to be, but then I’m not a bug person.
My husband was able to get photos of a couple of gnats in flight, which is apparently their primary mode of existence.
