Larva:
Siphon with three or more long, single, irregularly placed setae. The antennae are uniform in shape.
Adult Female:
Scutum mostly golden brown and most easily recognized by a pair of pale spots. Abdominal terga have broad apical bands.
A comment by Omar on an image posted by me (Tony T) as a Culex restuans with reference to the pale spots generated this comment:
"I can see how those can be tricky
But the two spots are usually not a good way to differentiate a restuans because sometimes they are not present." My emphasis.
Note also that C. territans has similar pale spots on the thorax.
Thus it appears that pale thoracic spots are of only limited use in identifying a C. restuans.
