Where are Cx. tarsalis found?

Where are Cx. tarsalis found?

• A. Only in North America
• B. Every country; agricultural, commercial, manmade sources
• C. Tropical rainforests
• D. Polar regions

Answer: (B)

Geographic range and habitat preferences are key when thinking about this mosquito. Cx. tarsalis is found primarily in North America, especially the western United States and nearby parts of Canada, with some presence into northern Mexico. It thrives in temperate environments and breeds in a variety of shallow, sunlit water sources, including irrigation ditches, ponds near agricultural lands, rice fields, and even man-made containers. Because of these climate and habitat needs, it isn’t distributed worldwide, nor is it typically found in tropical rainforests or polar regions. So the description that places its presence in North America best matches what’s observed, while the other options describe biogeographies that don’t fit this species.
