Which mosquito species is known to be particularly aggressive at any time of day or night, especially at night?

The mosquito species that is particularly aggressive at any time of day or night, especially at night, is indeed Aedes aegypti. This species is known for its aggressive biting behavior and is primarily active during the day, particularly during early morning and late afternoon. However, it can also feed during the night, making it a significant nuisance and vector for diseases such as dengue fever, Zika virus, and chikungunya.

While other species listed may exhibit different behaviors, Aedes aegypti stands out due to its adaptability to human environments and its capacity for biting at various times throughout the day and night. The other species, such as Culex pipiens, tend to have more distinct peak feeding times, often later in the evening or nighttime, and are not necessarily aggressive during the day.
