Aedes notoscriptus (Skuse, 1889)


[United States invasive]



Etymology: back (Gr), to write (L); refers to thorax “with several fine longitudinal lines”

Aedes notoscriptus is an attractively “spotty” mosquito, with clusters of bright-white scales on the ends of the palps and across the lateral thorax. Aedes notoscriptus is one of three species in the subgenus Rampamyia, which includes the Australasian taxa Ae. albilabris Edwards and Ae. quinquelineatus Edwards. It has one recognized subspecies—Aedes notoscriptus montanus Brug, originally described from Lembang, Java. Several studies have provided evidence for cryptic taxa but there have been no efforts to formally describe the species. Distinct genetic lineages have been noted in populations of Ae. notoscriptus in Australia and New Zealand, which correlate with wing centroid size. Allozyme data indicated at least five distinct genetic signatures in over 17 populations sampled—four in New South Wales and another in Darwin. Whole mitochondrial genomes revealed two distinct species, and geographical differences in egg morphology have also been reported, however there have been no efforts to formally describe the component taxa.

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

ADULT (illustrated): Head: Proboscis (P) dark-scaled with median pale ring.  Thorax: Scutum (Scu) with lyre-shaped lateral silvery lines, narrow median silvery lines and anterior sublateral golden lines of scales; postpronotum with small distinct lower patch of silvery scales; antealar area with distinct silvery scale patch. Wing: Scales all dark dorsally. Legs: Fe-II and Ti-III with anterior lines of pale scales along nearly whole length. 

LARVA (not illustrated): Head: Seta 1-C robust, sharply hooked; seta 5-C single. Abdominal segments: Without conspicuous stellate setae. Terminal segments: Comb scales in irregular triangular patch; siphon not pilose; siphonal acus large and broadly joined to siphon; seta 1-S short, <0.5 x length of siphon.

Immatures of the invasive, container-breeding Ae. notoscriptus s.l. can develop in a wide variety of natural containers—leaf axils, rock pools, tree holes, bamboo stumps, coconut husks and shells, palm fronds—and a variety of large and small artificial containers made of cement, wood and metal. Aedes notoscriptus s.l. has recently adapted to peri-domestic environs, where it is extremely common in roof gutters.


In New Zealand, Ae. notoscriptus s.l. is a ferocious biter and frequently enters houses to feed, but biting behaviors are known to vary. In native forests of New Zealand, Ae. notoscriptus was detected at both ground level and 10m up in the canopy. In Australia, the species is a common urban pest, biting people in shaded areas throughout the day. Its other proven hosts include dogs, brushtail possums, birds, cats, and flying foxes. Viral transmission competency varies geographically.
