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.
I could be wrong. I have seen them for 60 yrs and anyone who sees them also calls them male mosquitoes. Now I am going to check it out and see. It’s summer now and there will be a few of them flying around that I can snap a pic of and see.
I searched and got this for male mosquito. This looks exactly like what I am talking about. They are way bigger and have no long proboscis for drinking.
