Humpback flies usually live in which location?

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

Answer: (B)

Humpback flies are outdoor insects; they spend most of their life in open, outside environments where they can find breeding sites and food. The outdoor setting provides the moist, organic materials and exposure they need, which is why they aren’t typically described as living inside buildings. They may wander indoors briefly or perch on vegetation or around trees, but that doesn’t constitute their usual home. Water is associated with some stages of certain fly species, but adults don’t live in water, and trees aren’t the primary home for this type of fly.
