A friend of mine has a house on a western North Carolina creek bank. Once a year for the past three years, for a very short period of time, we have noticed very small (the size of a gnat) flying bugs that light up like fireflies. No one can tell us what they are, though old-timers in the area say they are only out for 10 to 12 hours a year -- and only if the temperature is warm enough and there is no rain or wind.
Re: What are the glowing, gnat-like insects seen once a year?
