Explanation of Names
Species name rutilus is Latin for "red with hints of yellow". Rutile is a titanium ore, and perhaps that is more the reference--the color of the mosquito is rather metallic (Internet searches).
Two subpsecies (New Jersey Mosquito Biology):
Toxorhynchites rutilus rutilus--southern part of range, including Florida, Georgia, Louisiana
Toxorhynchites rutilus septentrionalis--much of range, north to New York, Connecticut
Wingspan circa 12 mm, body length circa 7 mm
Very large, for a mosquito. Body is covered with shiny metallic blue scales. Proboscis prominent and curved upwards. Attracted to flowers.
Deciduous and other forests
July-September, early October (North Carolina)
Adults take nectar. Larvae feed on aquatic insects, especially other species of mosquites, becoming cannibalistic sometimes.
Breed in tree holes and other water-filled cavities. Larvae predaceous on other mosquitos. Overwinter as late-instar larvae or as adult (southern part of range?). Has been reared for biological control.
