In which habitats is Cx. erythrothorax found?

In which habitats is Cx. erythrothorax found?

• A. Foothills, coastal, SE desert; marshes, ponds with cattails
• B. Urban polluted water
• C. High-altitude alpine streams
• D. Desert sand dunes only

Answer: (A)

Cx. erythrothorax prefers wetlands with emergent vegetation, especially cattails, where shallow, still or slowly moving water provides ideal larval habitat. Its distribution in foothill and coastal regions and into parts of the southeast desert reflects these marshy, cattail-rich environments that sustain its larvae. The other options describe habitats that don’t match its breeding preferences: urban polluted water is typical for species adapted to nutrient-rich, dirty water; high-altitude alpine streams are fast-flowing and cold with little marsh vegetation; desert dunes lack standing water. So, foothills, coastal areas, and SE desert regions with marshes and ponds containing cattails best describe where this mosquito thrives.
