The type locality is Buenos Aires (Knight & Stone, 1977).
Disease relations: Between 1977 and 1980; the Gamboa virus, in Santa Fe Province, and the Gamboa and the Venezuelan Equine Encephalitis viruses, in Chaco Province, were isolated from specimens of Aedeomyia squamipennis in Argentina (Mitchell et al., 1985). The same virus was also isolated from Aedeomyia squamipennis in Honduras (Calisher et al., 1988), Panama, Ecuador (Calisher et al., 1981), Suriname, and Brazil (Dutary et al., 1989).
Larvae and pupae of Aedeomyia squamipennis have been collected in large swamp marsh depressions with grasses, sunlight, pH between 5.50 and 6.79, together with larvae of Nyssorhynchus albitarsis, Anopheles annulipalpis, Culex idottus, Culex brethesi and species of Mansonia, Psorophora and Uranotaenia. Adults were collected with CDC light traps with UV-light placed in a forested environment.
