Identification
Adult: Dark overall. Proboscis with distinct white ring at middle. Palps white-tipped. Wing scales dark. Abdominal terga with transverse basal pale bands, lacking median longitudinal stripe. Hind tarsomeres with pale rings basally. Lacks pale ring medially on first hind tarsomere.
Larva: Seta 1-S attached distal to pecten, pecten teeth evenly spaced, comb scales with subequal to subapical spinules, comb scales small, numbering 10-30, seta 6-III-V with 2-5 branches. Found in saltmarsh or mangrove habitat.
Range
coastal counties from New Hamphire to Mexico and beyond, scattered distribution inland, California from Monterey area south.
Habitat
Larvae in saltmarsh habitats or inland waterways, mangrove swamps etc. Also in salt ponds and other inland saline habitats.
Season
Major pests during summer and early fall.
Food
Larvae: Filter feeders
Adults: Males and females feed on nectar, females often fly far inland to take a bloodmeal from warm-blooded hosts. Often encountered by ships at sea when host seeking swarms are blown from shore.
Life Cycle
Oviposition occurs on bare mud of saltmarsh habitats, hatching stimulated by tidal inundation or rainfall-associated depth increases inland. Control methods can include flooding mudflats during breeding seasons to prevent oviposition.
Remarks
A very common nuisance mosquito in coastal areas, especially in the Southeast. Vector of dog heartworm.
