Not trying to debate bugs.... Fish would laugh if they knew all the fuss Fly fishers have made about bugs.
I've pretty much given away all my "bug books" or lent them out and not got them back... my tied flies for waters where I used to live were based on my experiences, essentially what type bug and where in the water column they wanted it at various times of year.... I suppose I will really enjoy the same learning curve here in TN!
BTW I too enjoy "pushing" a trout to take a dry or surface emerger when they're eating below. I tie the prettiest parachutes on the planet but my nymph tying absolutely scares fish away.
