Blue Wing OliveIt’s that time! In most rivers across the U.S., the first rising trout of the year are starting to appear. Chance’s are, this is what they are rising to…… Blue Wing Olives, or Baetis, like some fancy fly fisherman like to call them. You can find them hatching from now until about May, then again from September thru November. Typical sizes for these mayflies are 16 thru 20. If your going fishing this weekend, don’t leave home without them!
