Aedes vexans is best described as which type of species?

• A. Common floodwater/temporary pool species.
• B. Permanent pond species.
• C. Algae-feeding only.
• D. Dwell exclusively in trees.

Answer: (A)

Floodwater breeding habitat is the key idea here. Aedes vexans is the inland floodwater mosquito, using temporary pools that form after rain for its larval development. These ephemeral waters provide abundant breeding sites, and adults can become numerous after heavy rainfall. Describing it as a permanent pond species would be inaccurate because it relies on temporary, not stable, water bodies. It isn’t limited to algae for food in the larvae; they feed on a mix of microorganisms and organic matter in the water, not algae alone. It also doesn’t dwell exclusively in trees—resting sites are typically low vegetation near breeding areas, not exclusively in trees.
