INDO-ORIENTAL & PALEARCTIC REGIONS
Etymology: not stated
Originally forest-associated, Armigeres subalbatus thrives in rural and sub-urban areas, and is now most closely associated with human settlements with poor sanitation. Armigeres subalbatus is the only member of the subgenus Armigeres known to occur in the Palearctic Region.
Type locality: Japan
Type depository: U.S. National Museum, Washington, D.C., United States (USNM)
DIAGNOSTIC CHARACTERS (Click photos to view; mouse over and click large photo to zoom in.)
ADULT (illustrated): Head: Proboscis curved downward and laterally compressed; eyes ventrally with 2 rows of scales. Thorax: Scutum without pair of submedian golden stripes, lateral margins with complete line of pale scales; prescutellar setae present; postspiracular setae present; lower anterior mesepimeral seta present. Abdomen: Terga with lateral pale patches not extending dorsally; III–VI-S with apical dark bands. Legs: Fe-III posteroventral surface with broad white band extending to or nearly to apex.

Exemplar DNA sequences
Ar. subalbatus COI: HQ398903–08, KC970285, KC970288–89, KM497419, KT358440–42, MG242530.
Heavy rainfall causes the embryonic hatching stimulus in desiccation-tolerant eggs of Ar. subalbatus, leading to population peaks and biting nuisance. Armigeres subalbatus oviposit in contained sites with stagnant strongly polluted (foul) waters, or those with high organic content including natural containers—Pandanus axils, sago palm and banana stumps, fallen leaves and spathes, flower bracts, pitcher plants, bamboo, fruit shells and husks, hollow logs, rock and tree holes—and artificial containers, including septic tanks. Chitinous adaptations of the larval mandible and maxilla suggests that the species may be carnivorous, where particulate food resources are scarce.
Armigeres subalbatus bionomics follow distinct circadian rhythms, regulated by the phases of the moon. Host-seeking behaviors purportedly increase and decrease as the moon waxes and wanes. Biting cycles are crepuscular biting cycles, with highest activity at dusk (1700–1800) and a lesser peak at dawn. Egg hatching and adult eclosion occur exclusively in the daytime, while oviposition, larval molts and pupation occur at night. Females are highly anthropophilic, but will also feed on birds, cows and rabbits, and have been reported biting throughout the day in deep, dark forest.
