Aedes, Anopheles and Culex larvae Aedes, Anopheles and Culex larvae. An indication of the genera of mosquito larvae can be made from the length of the siphon. Anopheles have very short siphons (see below also), while Culex tend to have the longest siphons.
Aedes, Culex and pupa Aedes, Culex larvae and pupa. Both Aedes and Culex larvae hang down from the water surface at an angle. Compare this with Anopheles larvae below.
Aedes aegypti Aedes aegypti larva. Aedes agypti is the main vector of Dengue. For more information about Aedes aegypti click here.
Anopheles larvae Anopheles annulipes larva and pupa. Anopheles larvae have short siphons and lie parallel to the water surface.
Anopheles instars Anopheles instars (larvae stages).  Mosquito larvae go through 4 growth stages known as instars, before moulting to the pupal stage.
Coquillettidia larvae Coquillettidia larva. These larvae have highly developed siphons, which are adapted for piercing plant tissue. It is from here that they obtain their oxygen (rather than the water surface).
Culex quinquefasciatus Culex quinquefasciatus larvae. This is a common domestic mosquito, which invades houses. For more information on Culex quinquefasciatus, click here. (Thanks to James Indsto of the ICPMR for kind use of the photograph).
Emerging adult Emerging adult. This adult Culex quinquefasciatus is emerging from a split that develops along the thorax of the pupa.
Aedes camptorhynchus Larval Aedes camptorhynchus. This saltmarsh breeding mosquito is a noted vector of Ross River and Barmah Forest virus along the southern coast of Australia from the NSW/Vic border around to Perth. For more information on Aedes camptorhynchus, click here.
Aedes camptorhynchus larvae A single larval Aedes camptorhynchus.
