There was no blood on the floor, not a single fly in the air.

Not so much as a single fly killed on that eight-foot blade.

A single female fly can lay in upwards of two thousand eggs in its life.

The room was hot but it was clean, without a single fly or cigarette butt.

Why go to the trouble of squashing a single fly when you're about to exterminate the entire species?

Not a single fly hovered in the air.

I hope his new single flies off the charts, this man has worked very hard and deserves nothing but the best!!!

Then the scientist may sit motionless for hours to observe the behavior of a single fly without disturbing it.

For river fishing, a single fly was used on a 10-foot leader.

Inside the kennel: peace, darkness, and not a single varicolored fly.
