Facts: House fly adults are 1/4 to 5/16 inch long. The top part of the thorax is dusty gray and contains four equally broad stripes running from front to back. The fourth wing vein makes a sharp bend to the outside and almost meets the third at the wing tip. Adults have sponging and sucking mouthparts, while larvae have hooks in their mouthparts for tearing.
