First two states correspond to species of Culex and Culiseta genus respectively.
Most Aedes species have a pair of siphonal tuft inserted close to the middle or near the apex of the siphon but species belonging to subgenus Rusticoidus have additional scales on the dorsal part of the siphon.
This question leads to species belonging to Culex genus
This question leads to species belonging to Culiseta genus
This question leads to species belonging to Aedes genus
This question leads to species belonging to Aedes genus, Rusticoidus subgenus.
