Fairbanks, AK Posts: 1113	Many thanks to user Softhackle for digging up this link. I knew about the thread from back when it started, but I wasn't able to find it when I went back to look last night. Good work! Fly Fisherman Magazine forum topic with two pictures of a H. culacantha dun. I've added the species to the "live" part of the database and put up a rudimentary page where I can compile any more information we find.
