Where are humpback flies typically found?

• A. Outside
• B. Inside buildings
• C. In water
• D. In trees

Answer: (A)

Humpbacked flies are tied to outdoor breeding sites. They develop in decaying organic matter, which is most common outside—things like compost, rotting vegetation, manure, and damp outdoor debris. That outdoor environment provides the moisture and microbes these flies need to develop, so they’re typically found outside rather than inside. They may wander into buildings, but their primary habitat is outside. They aren’t associated with water bodies, and trees aren’t their usual setting, which is why outside is the best fit.
