Is this a "midge"?
No, this is not a midge. It is a mayfly. They do not sting and can be considered beneficial as they are a main menu item for fish this time of year. Our entomologist said that these are what the fly fisherman attempt to mimic when they tie flies. Interestingly, these insects don't even have mouthparts- their life is so short, they just hatch, mate and die.
