In my experience Black flies[1] and no-see-ums[2] are far worse (not counting mosquitoes born disease). It's like a massive angry cloud of micro horseflies that intend to dismember you bite by bite.

The Blackfly song has it right then? Thank you National Film Board of Canada: https://www.youtube.com/watch?v=f389hIxZAOc

Pretty much - although after living with it for 4 year I can report it's often worse. =) The local bookstore gave a discount for the first bite of the season if you lived long enough to collect.

FWIW black flies are also disease carriers.

While technically true, I think that's in tropical Africa. Are there also diseases that they carry in North America? Even without disease, I tend to agree with the OP that black flies are worse than mosquitoes, and don't think I've ever heard of anyone getting a disease from a black fly bite in the US or Canada.

Yeah, they can, I was just commenting on the physical experience as to which insects would keep me away from the northern latitudes.
