What fly has four dark stripes on the back of its thorax?

The house fly is characterized by having four distinct dark stripes running down the back of its thorax, which is a key identifying feature. This striping pattern sets the house fly apart from other types of flies, as they may lack such markings or exhibit different features. Understanding the physical characteristics of pest species, like the house fly, is crucial for effective identification and management in pest control.

Cluster flies, for instance, do not have this specific striping pattern, and fruit flies are much smaller with different coloration and body structures. Blow flies also differ in appearance, often appearing metallic and lacking the striped thorax of the house fly. Recognizing these details can greatly enhance the accuracy of pest identification in real-world scenarios.
