Note that 'Ochlerotatus notoscriptus' prior to 2000, was known as 'Aedes notoscriptus'.

Characteristic Features

Male Aedes notoscriptusFemale: A smallish to mid-sized dark species with conspicuous pale markings and banded legs; proboscis with median white band; scutum with narrow dark scales and with silvery (sometimes golden) scales forming conspicuous 'lyre' shaped pattern of curved laterals, a long central and short sub-lateral lines; wings all dark scaled; hind leg femur and tibia with pale stripe, tarsi banded and last segment may be all white; abdominal tergites dark with basal patches or constricted bands separated from lateral patches, sternites mostly pale scaled from base but terminal segments may be predominantly dark. (Click here for a large photograph of the adult).


Similar Species

Adult females may be confused with Oc. aegypti and Oc. mallochi because of similar scutal pattern but those species have no band on proboscis.


Geographic Distribution

NSW, Vic, SA, Tas, (also Qld, NT and WA); domestic and also sylvan in forested areas with tree-holes and/or rockpools.


Habits & Habitats

Adults readily attack humans by day in shaded areas but also feed during evening, night and early morning.


Vector & Pest Status

This species is arguably the major domestic pest species in southeastern Australia; it has been incriminated as an important vector of dog heartworm, has been shown to be able to carry Murray Valley encephalitis, and transmit Ross River and Barmah Forest viruses in laboratory studies. Any role as a vector of arboviruses remains unknown.
