- C. inornata mosquito species that is a secondary or suspected vector of Western equine encephalitis and California group encephalitis within the United States.

- C. melanura a species of mosquito that is the principal endemic vector of Eastern equine encephalomyelitis virus; since this species feeds primarily on birds, other mosquitoes (Aedes spp.) transmit the virus from birds to humans and horses.
