Which of the following is true about Ochlerotatus atlanticus?

• A. Common in coastal plains after heavy rain; medium brown; no banding on proboscis/legs; wide whitish-yellow thorax stripe; larvae in temporary woodland/field pools; persistent biter, even during daytime in shade/sun.
• B. Bites only at night; not a nuisance.
• C. Breeds in permanent water.
• D. Not a nuisance in coastal regions.

Answer: (A)

The main idea here is recognizing species-specific traits of Ochlerotatus atlanticus, including where it breeds, how it looks, and when it bites, because these factors guide monitoring and control decisions. This species is typically found in coastal plains after heavy rain and uses temporary pools formed by runoff or small depressions, not permanent water. Its appearance includes a medium brown color with a wide whitish-yellow stripe on the thorax and no banding on the proboscis or legs, which helps distinguish it from other mosquitoes that show leg or proboscis banding. Importantly, it bites persistently and can feed during daytime as well as in shade or sun, meaning it is not limited to nighttime activity. These combined traits—coastal, post-rain temporary-water breeding, distinctive body markings, and daytime biting behavior—make the described statement accurate. The alternatives conflict with its known ecology or behavior: it does not breed in permanent water, it does bite during the day, and it can be a nuisance in coastal regions after rain.
