Etymology: not stated [snow, snowy (L)]

Despite being a tropical species, Aedes niveus was named after the Latin name for snow, in reference to the heavy dusting of white scales adorning the top of its scutum. Originally described based on specimens from Oras, Samar in the Philippines, Aedes niveus s.s. is known only to occur from the islands of the Philippine archipelago. Aedes niveus is the nominotypical member of the Niveus Group—widely distributed from Pakistan to New Guinea—which comprises dozens of closely related species, mainly identifiable only by characters of the male genitalia. The Niveus Group comprises mainly zoophilic species but some, including Ae. niveus, are important vectors. Aedes albolateralis (Theobald) is a competent vector of dengue virus, being almost as susceptible to DEN-2 as Ae. albopictus (Skuse), Ae. harinasutai Knight is the principal vector of sub-periodic Wuchereria bancrofti in western Thailand, and Ae. niveus s.l.

Type locality: Oras, Samar, Philippines

BIONOMICS

Immatures

Tree holes are the typical immature habitats of Aedes niveus s.s.

Adults

Female Aedes niveus s.s. are day biters. Although primarily zoophilic, they do bite humans and the species is an important vector of periodic Wuchereria bancrofti filariasis in the Philippines. Aedes niveus s.l. are thought to play a significant role in the sylvatic dengue cycle in Borneo.
