How Horseflies Bite You 😨

When a horse fly bites you, it presses six needle-like tools against your skin. Two of them have sharp edges, so they slice you open like scissors, while two more have tiny teeth like a saw, sawing up and down to tear open your blood vessels until they burst and you start to bleed. Next, a hollow blade pumps in spit, which stops the cut from sealing so the blood keeps flowing out, as its spongy tip wraps it up.
