Psorophora ciliata is a species of large mosquito indigenous to North America east of the continental divide.

Psorophora ciliata are relatively large mosquitoes compared to other species within the genus, with a wingspan of 7–9 mm.

[1] Campos, Fernandez, and Sy found in their 2004 study that P. ciliata were frequent predators to the mosquito species Ochlerotatus albifasciatus in Buenos Aires, Argentina and impact the populations of O.

[5] Females are aggressive, preferring to feed on large mammals,[2] and are most active during spring and summer in woodlands or fields during the day or night.

Typically, females in the genus are capable of laying their eggs on dry or damp land to hatch months or years later, depending on the species.
