Which mosquito species develops in the early spring from melted snow?

• A. Aedes vexans
• B. Culex pipiens
• C. Sedes ventrovittis
• D. Psorophora columbiae

Answer: (C)

The correct answer is Sedes ventrovittis, a mosquito species that is known to develop in the early spring from melted snow. This species has adapted to thrive in cooler temperatures and relies on the seasonal melting of snow to create suitable breeding habitats. The life cycle of Sedes ventrovittis begins when snow melts and fills low-lying areas, allowing eggs deposited before winter to hatch and develop in these temporary pools. In contrast, other species such as Aedes vexans and Culex pipiens have different breeding preferences and may be more associated with warmer weather or standing water that accumulates throughout the spring and summer. Psorophora columbiae is known for its flooding-type breeding sites often in response to significant rainfall rather than snowmelt. Understanding the specific life cycles and breeding habits of these mosquito species is crucial for effective pest management and public health measures.
