Aedes sollicitans (Walker, 1856)


[China invasive]



Etymology: not stated [disturbing, harassing (L)]

Aedes sollicitans is most closely related to Ae. taeniorhynchus (Wiedemann), which, along with Ae. mitchellae (Dyar) and Ae. nigromaculis (Ludlow), make up the Culicelsa Group of the subgenus Ochlerotatus. Aedes sollicitans is a salt marsh floodwater mosquito, that dominates many coastal areas of the eastern and southern United States, as far north as northeastern Canada, and extends south into Mexico and the Caribbean.

Type locality: Charleston, South Carolina, United States

Type depository: Natural History Museum, London, England, United Kingdom (NHMUK)
