I have seen a few of them around both up at the lake and back at my home place. I am sure they are going to really cut loose soon. The midge flies were sure hatching good over the holiday weekend. Last year I fished after dark one evening. Big mistake everything was covered. lol- After the trip back home, I noticed the next day , my building where I store the boat had mayflies all over the place. Quite the little hitch hikers to be able to stand the 70 mph wind speed of heading home.
