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.
My only mosquito problem is the noise they are making when they hit the electrical fly squatter.
I activate it when getting ready for bed, and when I turn off the lights, it only takes a few seconds before the fireworks starts. No hits so far this year.
