a tiny flying chainsaw that scissors your skin open and laps the blood
means A large, fast biting fly whose females cut into the skin of horses, livestock, and humans to feed on blood, leaving a painful welt.
from A plain English compound, joining "horse" and "fly" — the bug named for the animals it most famously torments. Both halves are deeply native: "horse" goes back to Old English "hors," and "fly" to Old English "flēoge," from a Germanic root tied to flying. The naming logic is ancient and obvious — humans have watched these flies harass their horses for as long as they've kept them — and similar straightforward names show up across European languages.
