No See-em’s are just plain annoying. Skeeters are also, but do pose more problems with possible disease and for some people get welts. That really never happens with me. But Green Fly’s, especially over in the coves like Hemlock and Coast Guard or the slow parts of the channels are for me the worst. I have gotten bitten where it took months to heal and to this day I have some tiny scared bumps from them. I bet they are carrying some nasty crap, maybe not disease that we know of, but whatever gets under the skin is not good. At least that’s been my experience.
