Eastern Saltmarsh Mosquito
For coastal New Jersey, mosquito pressure cannot be understood only by inspecting buckets. Aedes sollicitans develops in salt-marsh habitat and can disperse inland after large broods emerge.
Brightly scaled, coastal, flood-triggered and capable of moving inland.
Rutgers describes a medium-sized mosquito with a conspicuous pale band on the proboscis, banding on the hind legs and a pale stripe along the abdomen. Larvae develop in salt-marsh depressions flooded by high tides or heavy rain.
Coastal setting and distinctive banding help, but exact confirmation is still best with a specimen.
Adult identification
Rutgers notes a conspicuous white band around the center of the proboscis, pale bands on portions of the hind legs, mixed dark and pale wing scales and a pale longitudinal stripe on the abdomen.
Larval habitat
Eggs are laid on moist substrate around depressions in grassy salt marshes. High tides and heavy rain create the pools that trigger hatching.
Rapid development
Because marsh pools can dry quickly, larvae develop rapidly; Rutgers notes adult emergence can occur in only several days under favorable conditions.
Biting behavior
Host seeking is primarily around twilight, especially evening, but resting females may bite during the day when a host enters their area.
Inland movement
Rutgers describes gradual inland dispersal from coastal marshes, influenced by wind, with many broods moving several miles from the coast.
What it means for a yard
A coastal homeowner can have excellent source reduction and still experience pressure from marsh-produced adults. County coastal mosquito-control programs therefore matter greatly.
Asian tiger mosquito
Saltmarsh mosquitoes can have pale bands, but their ecology is completely different. The tiger mosquito is a small-container suburban breeder; sollicitans is tied to flooded salt-marsh habitat and coastal dispersal.
Identification questions
Can saltmarsh mosquitoes reach homes away from the marsh?
Yes. Rutgers describes inland dispersal influenced by winds and host-seeking movement.
Do they only bite at night?
No. Peak host seeking is around twilight, but daytime opportunistic biting can occur.
Can I eliminate the breeding source in my yard?
Often the major source is marsh habitat beyond the property, so public mosquito control can be an important part of management.
