Etymology: not stated

The legs, abdomen, and thorax of Ae. scutellaris are ornately decorated with thick rings and lines of silvery-white scales, giving it a decidedly striped appearance. It is the nominotypical member of the Scutellaris Group which comprises over 40 species including Aedes albopictus (Skuse), and is further subdivided into the Albopictus and Scutellaris Subgroups. All members of the Scutellaris Subgroup have well-developed supraalar white lines, with broad flat scales extending over the wing root towards the scutellum.

Type locality: Aroe Islands, [New Guinea]

Type depository: Natural History Museum, London, England, United Kingdom (NHMUK)

DIAGNOSTIC CHARACTERS  (Click photos to view; mouse over and click large photo to zoom in.)

ADULT (illustrated): Head: Proboscis entirely dark-scaled; palpus with white scales at apex; pedicel with mesal and lateral scales. Thorax: Scutum with median silvery stripe; Lower proepisternal and lower mesepimeral scales white; paratergite with white scales; postpronotal scales present; subspiracular area with white scales; supraalar area with line of well-developed, broad white scales. Abdomen: Terga with complete or nearly complete pale bands. Legs: Fe-II without anterior median white line; Ta-I–VIII with basal pale bands.

LARVA (not illustrated): Head: Seta 1-A very small, weakly developed; seta 4-C prominent, many branched; seta 5-C single, about same level as 7-C; setae 4,6-C distinctly anterior to 7-C.  Terminal segments: Comb scales in single row; CS spatulate, apex rounded but slightly narrowed apically, surrounded by short fringe; pecten with 10–16 spines; PS with 1–3 ventral and 1 or 2 small dorsal denticles; four pairs of seta 4-X; seta 1-S inserted at or before middle of siphon.

BIONOMICS

Immatures

Female Ae. scutellaris preferentially oviposit in rough textured containers with low levels of reflected light, including in the crevices of coconut shells, tree holes, palm fronds, Pandanus leaf axils, bamboo, in discarded trash such as empty cans, and rarely, in small ground pools and wells. Immatures develop quicklyegg to imago in ˜7 days for males and ˜9 days for females.

Adults

Copulation in Aedes scutellaris takes place during flight and mating occurs close the host. Peak biting occurs in the evening, but female Ae. scutellaris will bite opportunistically during the day in shaded areas.
