You all have been talking lately about this odd fly called a cicada. From what I can gather, there is one hatch every 17 years, and the hatch is huge. What do they look like? I would also like a lot of other miscellaneous information on them.
They sound like salmonflies sort of, which hatch here in rivers for maybe 1 week every year. These are huge 4 inch stoneflies that are brownish-reddish in color, and when they are hatching, the surface is in a feeding frenzy of monster rainbows and browns. It is a great hatch.
Any information on cicadas, or any other odd, rare fly would be interesting to here about.
