You might not have much luck fishing this terrestrial right now but come the spring it might be something to try out when other flies fail to produce. Word has it that trout will go after these just like any other beetle but be for warned that if trout eat to many of them they will get sick. I suspect that if you are targeting a fish that has had this experience then you might want to choose a different fly. As for fishing this little beetle for bass or sunfish... Go For It. those warm water fish eat just about anything.
I hope all of you had a great Christmas Day and got some good fishing gear.
