Where are Coquillettidia perturbans eggs laid singly?

• A. Open lake bottoms
• B. Rice paddies
• C. Cattail marshes
• D. Tree-lined streams

Answer: (C)

Coquillettidia perturbans lays eggs singly on emergent vegetation in wetlands because its larvae rely on air obtained from underwater plant tissues. The females choose marshy areas with abundant aquatic vegetation, such as cattails, so newly hatched larvae are immediately next to the plant roots and stems they use for respiration. This makes cattail marshes the most suitable habitat for these eggs. Open lake bottoms lack the needed vegetation, rice paddies are a different agricultural habitat, and tree-lined streams don’t provide the same dense marsh vegetation that these mosquitoes rely on.
