Aedes vittatus
Aedes vittatus is a species of mosquito that was first described in 1861 as Culex vittatus from specimens collected on Corsica.[1] In 2000, the species was transferred to the newly erected subgenus Fredwardsius as the type (and only) species representing the subgenus.[2]

Bionomics
The species is found in Algeria, Angola, Bangladesh, Benin, Botswana, Burkina Faso, Cambodia, Cameroon, Central African Republic, China, Comoros, Côte d'Ivoire, Democratic Republic of the Congo (Zaire), Djibouti, Ethiopia, France, Gabon, Gambia, Ghana, Guinea, India, Iran, Italy, Kenya, Laos, Liberia, Madagascar, Malawi, Malaysia, Mali, Mozambique, Namibia, Nepal, Niger, Nigeria, Pakistan, Portugal, Saudi Arabia, Senegal, Sierra Leone, Somalia, South Africa, Spain, Sri Lanka, Sudan and South Sudan, Tanzania, Thailand, Tunisia, Uganda, Vietnam, Yemen, Zambia and Zimbabwe.[3] In October 2019, it was discovered to be established in the Dominican Republic, the first report of its presence in the Americas.[4]
The immature stages develop in log holes, hoofprints, boats, wells, tree trunks, tree holes, bamboo cups and pots, occasional utensils, rock pools, rock holes, in pools in rock outcrops or river beds, and coral, and occasionally at the peak of the breeding season, in open concrete floodwater drains.[5] Immature stages have been found in association with Aedes albopictus, Aedes malayensis, and Culex species.[5]
In northern Nigeria no adults were caught in traps baited with goats, sheep, monkeys and pig; porcupine was the most important host in the area.[5]
Medical importance
A demonstrated human-biter,[5] Aedes vittatus can transmit yellow fever virus in monkeys in the laboratory and was a suspected vector in the 1940 Nuba Mountain epidemic in Sudan in which an estimated 15,000 human cases and 1,500 deaths were reported.[5] Aedes vittatus is potentially capable of transmitting Zika virus, the causative agent of Zika fever.[6][7] The adult females have a short crepuscular biting period, with maximum activity between 1800 and 2100 hours.[5]
