ORIENTAL & PALAEARCTIC REGIONS
Generic abbreviation: Ar.
Type species: Culex obturbans Walker
Etymology: armor bearer (L)
The genus Armigeres contains 58 large species subdivided into two subgenera: Armigeres (40 species) and Leicesteria (18 species). All are restricted to the Oriental Region, except Ar. (Lei.) annulipalpis (Theobald) (whose range reaches south to Ceram Island) and Ar. (Arm.) subalbatus (Coquillett), which stretches north to China, Korea and Japan. As adult females, Armigeres are easily recognized by their down-turned and laterally flattened proboscis and two long distinctive rows of scales that separate their eyes; the lack of pecten in larvae differentiates Armigeres from all other Aedines.
DIAGNOSTIC CHARACTERS (Click photo to zoom in.)
ADULT (illustrated): Head: Male palpus about as long as proboscis; female proboscis laterally compressed and slightly down-turned at tip; palpus long, slender and upturned, three-segmented with the last two segments nearly bare. Eyes separated ventrally by two long rows of scales. Thorax: Prespiracular setae absent; postspiracular area with scales, seta present or absent; base of small mesomeron more or less even with base of C-III; head scales primarily broad and flat dorsally; acrostichal and dorsocentral setae absent. Wing: Alula and upper calypter with marginal hair-like scales.
LARVA (not illustrated): Terminal segments: Pecten absent

Armigeres immatures are found in natural small container habitats where waters are extremely foul or with high organic content, including tree holes, hollow logs, tree, banana and palm stumps, split and broken bamboo, pitcher plants, leaf axils, fallen leaves/spathes and fallen fruit husks. In urban areas, immature Ar. subalbatus are common in septic tanks, cesspools and cement tanks. The modified larval mouthparts of some Armigeres (Armigeres) species—including Ar. obturbans and Ar. subalbatus—suggests that some species may be predatory, or that their modified structures are used to rasp at fruit husks.
Although Armigeres species are mainly associated with jungle and jungle-edge plantations, some species now thrive in urban and semi-urban areas. Armigeres (Leicesteria) species are associated with lowland and dipterocarp forests, but never primary forests. Many species of Armigeres readily attack man. Often are reported to bite during the day, Armigeres females are most active at dawn and dusk.
Armigeres eggs are laid singly and are susceptible to desiccation. Females of some Armigeres (Leicesteria)—Ar. annulitarsis (Leicester), Ar. balteatus Macdonald, Ar. flavus (Leicester), Ar. inchoatus Barraud, Ar. magnus (Theobald) and Ar. traubi (Macdonald)—gather all their laid eggs and attach them to their hind legs, before transferring and releasing them as eggs or incompletely hatched larvae onto preferred water surfaces, or into tiny protected habitats such as bamboo insect rot holes (Ar. flavus). This curious behavior is evidenced in museum species, preserved with egg batches attached to the hind legs.
