Species restuans (White-dotted Mosquito)
Explanation of Names
Culex restuans Theobald, 1901
- scutum copper-colored, sometimes with 2 pale spots (as seen here)
- thorax sides have patches of pale scales
- abdomen has white basal bands, legs dark
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.
CA-FL-NB-BC / Mex. (2)
Larvae are found in natural and artificial containers. Larvae are also tolerant of polluted waters. (3)
The larvae are found in a wide variety of aquatic habitats, such as ditches, pools in streams, woodland pools, and artificial containers. (2)
The species reaches its greatest abundance in the spring and early summer throughout most of its range, and occurs in lesser numbers during late summer and autumn. The larvae and adults may be found throughout the year in the extreme South. (2)
Females prefer the blood of birds.
Life Cycle
Adult females overwinter in well-protected areas. This is a multivoltine species.
