Eastern Saltmarsh Mosquito

aedes sollicitans

The Eastern Saltmarsh Mosquito (Aedes sollicitans) is a notorious insect primarily found along the Atlantic and Gulf coasts of North America. Renowned for its aggressive biting behavior, especially during daylight hours, this species is a significant pest in its range. While both male and female mosquitoes feed on plant nectar for energy, the females require a blood meal to provision their eggs, making them a vector for various pathogens. Its ability to thrive in brackish waters and travel considerable distances from its breeding grounds makes it a persistent presence in coastal communities. Despite its reputation as a nuisance, the Eastern Saltmarsh Mosquito plays a role in coastal ecosystems, serving as a food source for other organisms and participating in nectar consumption.

Habitat: Found in coastal saltmarshes, brackish pools, and temporary floodwaters influenced by tidal cycles.

Appearance

The Eastern Saltmarsh Mosquito is a medium-sized mosquito, typically measuring between 0.5 to 0.8 centimeters in length. It has a dark body adorned with distinctive white bands on its legs and proboscis. A key identifying feature is the golden-scaled mesonotum (the dorsal surface of the thorax), which gives it a somewhat striped appearance. Its wings are translucent, and its overall build is delicate yet robust enough for its long-distance flights.

Interesting facts

Despite its preference for coastal areas, it can sometimes be found many miles inland due to its impressive flight capabilities, especially after strong winds.

The eggs of the Eastern Saltmarsh Mosquito are laid individually on damp soil in depressions within saltmarshes, and can remain dormant and viable for years until flooded by high tides or rainfall.

This species is a known vector for Eastern Equine Encephalitis (EEE) virus in humans and horses, as well as dog heartworm (Dirofilaria immitis).

Unlike many other mosquito species, Aedes sollicitans is a strong flier and can travel up to 160 kilometers (100 miles) from its breeding grounds, significantly expanding its impact zone.

Special abilities

This mosquito species is capable of flying many miles (up to 160 km) from its breeding grounds to find blood meals, allowing it to impact areas far inland from saltmarshes.

Unlike many mosquito species that are crepuscular or nocturnal, Aedes sollicitans is known for its persistent and painful bites during both day and night, making it a significant outdoor nuisance.

Its larvae are uniquely adapted to develop in highly saline or brackish water environments found in saltmarshes, a habitat unsuitable for many other mosquito species.

Diet & Feeding

Males and females feed on plant nectar for energy and survival. However, female Eastern Saltmarsh Mosquitoes require a blood meal, typically from mammals or birds, to obtain the necessary protein and nutrients for egg maturation.
