Aedes atlanticus Dyar & Knab, 1906




Etymology: Atlantic; oceanic region of North America

Aedes atlanticus is a pest species across much of its range. Although generally dark in color, Aedes atlanticus have a broad median stripe of white scales on their heads that stretch forward between the eyes, and a narrow strip of silvery-white to pale yellow scales along the whole length of their scutum. Aedes atlanticus is one of ten species assigned to the Protoculex Group.

Type locality: New Jersey, and Sanford, Florida, United States

Type depository: Type non-existent (NE)

DIAGNOSTIC CHARACTERS  (Click photos to view; mouse over and click large photo to zoom in.)

ADULT (illustrated): Head: Lateral black scale patches extend forward to eye margin. Thorax: Median longitudinal white stripe along entire length of scutum, narrower than lateral brownish areas.  Antepronotum and postspiracular area without pale scales; paratergite scales absent; postprocoxal membrane bare; subspiracular scales absent. Leg: Ta-III without pale bands.

LARVA (not illustrated): Head: Setae 5,6-C gradually tapering from base; seta 8-C long, reaching forward to base of seta 5-C. Terminal segments: Comb scales 4–6, in single row; siphon width about equal to width of segment X; siphon index c. 2.0–2.5; seta 1-S inserted at or beyond last pecten spine; seta 2-X distinctly shorter than seta 3-X; anal papillae ≤5 x width of segment X.

Ae. atlanticus  COI: JX259518–19, MG242469




Aedes atlanticus oviposit in a wide variety of floodwater sites, both in open and wooded areas. Larvae are found in temporary pools in open fields and woodlands, and often in association with Ae. infirmatus Dyar & Knab. In coastal areas, the immatures can sometimes occupy brackish water sites. In Virginia, larvae have been reported from March to November.


Female Ae. atlanticus are crepuscular—commonly found biting at dawn and dusk in shaded areas, but they can also be lured to feed in bright sunlight. Hosts include humans and a wide range of mammals, birds and reptiles. Adults are closely associated with the immature habitats. They are weak fliers, with short flight ranges noted of only up to half a mile. Peak adult abundance occurs in spring and fall.
