Culex restuans larvae have pecten
spines on the basal third of the siphon,
followed by long irregularly spaced seta.
The antennae of the Culex
restuans are not constricted, and they have seta attached near the
middle of the antenna.
Culex restuans have shorter antennae
than either
Culex tarsalis or Culex pipiens, and the restuans
antennae are not constricted.
