Banded Mosquito - Culiseta annulata

Description

Wing span 13 to 15 mm.  This species is one of the largest mosquitoes, the wings are spotted and the legs and abdomen are boldly banded. Members of this family have a long forward pointing proboscis and the males have feathery antennae.

Similar Species

The similar, but smaller,  Asian Tiger mosquito (Aedes albopictus) only has a wingspan of 7 to 8 mm and the thorax of Aedes albopictus has a single white central line from front to back; this does not occur in Banded Mosquito (Culiseta annulata).
