Common malaria mosquito vs Northern house mosquito
The tail-up rest is the field mark. Aedes and Culex sit more parallel to the surface. Spotted wings help on this species. Malaria in the U.S. is rare; the mosquito is still here.

- Cattail mosquito identification (Coquillettidia perturbans)
Range and season

Lakeside cabins, vegetated ponds, and night porches in the eastern and central U.S.

Common questions
Do we still have malaria mosquitoes in the U.S.?
Anopheles species that can transmit malaria still live here, but local malaria transmission is rare. Travel-related cases are the main concern.
How can I recognize Anopheles?
They often rest head-down, tail-up, at a sharp angle, unlike Culex or Aedes which sit more parallel to the surface.
When do they bite?
Typically from dusk through the night near still water.
What mosquito rests with its tail in the air?
Anopheles. Unlike Culex or Aedes, it often sits head-down, tail-up at a sharp angle.
Is there malaria in the United States?
Anopheles still occur. Local malaria is rare. Travel-related cases are the usual concern.
How do I identify Anopheles vs Culex?
Anopheles often rest tail-up. Palps are long. Culex sit flatter and look plain brown.
