A female Coquillettidia linealis. This is a common species from southeastern Australia with distinctive golden stripes on its thorax. It breeds in permenant vegetated freshwaters and can be a serious nuisance pest around its breeding areas. For more information, go to the Coquillettidia linealis Fact Sheet. |
|
The larvae of Coquillettidia linealis have a modified siphon, designed to pierce plant material, from where they gain their oxygen. |

|
Coquillettidia linealis lay their eggs in rafts, which float on the water surface. The larvae hatch out from underneath the raft. The caps (operculum) indicates that the larvae have already hatched from this raft. |
|
This is a very distinctive mosquito of orange appearance. Larvae breed in swamps, lagoons and creeks. This species is a major pest in many parts of northern Australia but is only occasionally collected in northern NSW. Susceptible to Ross River infection in the laboratory although vector status is unknown. |
|
The same mosquito, almost fully blood engorged. |
 |
Like Coquillettidia linealis above, Coquillettidia xanthogaster lays their eggs in rafts. |
Mansonia uniformis
 |
This mid-sized mosquito occurs throughout much of Australia and is common in both the coastal and inland regions of New South Wales. It can be a major nuisance pest in northern parts of Australia. For more information, go to the Mansonia uniformis Fact Sheet. |
 |
The same mosquito, almost fully blood engorged. |
 |
Mansonia larvae have a modified siphon designed to pierce plant material from where they gain their oxygen, normally the larvae do not rest at the surface as in this image. |
 |
Larvae of Mansonia uniformis attached to plant roots. |
 |
The pupa of Mansonia uniformis. Like the larvae, the pupa have modified trumpets for piercing plant materials to gain their oxygen. They normally only rest on the water surface like this just before emerging. |
 |
The eggs of Mansonia uniformis are layed in a raft usually attached to plant material. |
 |
This Mansonia species occurs in northern Queensland and can be a pest species. |
 |
Like Coquillettidia, Mansonia larvae have a modified siphon designed to pierce plant material from where they gain their oxygen. |
 |
