Are black flies only found in still water?

• A. True
• B. False
• C. Only in swamps
• D. Only in rivers

Answer: (B)

Black flies are not exclusive to still water; they are commonly found in a variety of aquatic environments, including fast-flowing streams and rivers. These insects lay their eggs in clean, running water, where the larvae can thrive. While still water bodies may support other mosquito species and some aquatic life, black flies prefer habitats with sufficient water flow, which is typically rich in oxygen and food sources. Therefore, the statement that black flies are only found in still water is false. It is important to recognize their adaptability to diverse habitats, which allows them to flourish in various ecosystems beyond just stagnant water areas.
