I've had to deal with huge swarms of these things every summer for the few years I've lived a mile away from a lake. I assumed they were mosquitoes until recently.
Is it some kind of midge fly? How can you tell? If I were to make an uneducated guess, I'd say it's not a mosquito because there's not a straight proboscis.
So I'd consider myself a very amateur entomologist so am very open to being wrong here, but that's not a thing to my knowledge; if anything, the males tend to be smaller. You might be seeing two different species, or are misidentifying another insect for a male mosquito.
