Ecological Role
Acts as a scavenger and decomposer, breaking down organic waste. They are also a primary food source for many birds, reptiles, and spiders.
Easily Confused With
Stable flies (Stomoxys calcitrans) look similar but have piercing mouthparts. Flesh flies (Sarcophagidae) are larger with three stripes on the thorax instead of four.
Observation Tips
Easily observed on sunny surfaces where they bask to regulate temperature. Use a macro lens for photography as they are very sensitive to movement and fly away quickly.
Interesting Facts
House flies don't have teeth; they must liquefy solid food by regurgitating saliva onto it before sponging it up. They can taste with their feet.
