Dear Client,

Yes, this is a type of mosquito.   Some people call it a 'Shaggy-Legged Gallinipper' -- Psorophora ciliate. One of the characteristics that helps identify this species is that it is one of the biggest mosquitoes in N. America. The length of your mosquito should be about 1/2 inch long.  FMI see: https://en.wikipedia.org/wiki/Psorophora_ciliate

This mosquito is aggressive and will bite humans.  The bite is somewhat painful but the mosquito is not know to carry any human diseases.  The larvae of this mosquito species will feed on other mosquito species so it may be considered beneficial to some scientists until they get bitten by the adult mosquito.
