Inland Floodwater Mosquito - Aedes vexans

This is an adult female Aedes vexans that is half gravid (full of eggs). You can see that 1/2 of her abdomen is still dark with a bloodmeal, while the other half is whitish and gravid with eggs. As she digests the rest of the blood, her entire distended abdomen will become white and gravid.

Aedes vexans are most easily characterized by their unbanded proboscis, scutum with short brown scales, but no obvious pattern, the pale basal, bilobed bands on the abdominal terga, and the narrow basal bands on the hindtarsomeres.

Aedes vexans is a known vector of Dirofilaria immitis (dog heartworm).

This mosquito was attracted to a moth light.
