I have a request...hopefully, someone can help me. Can anyone who is fishing in the Sierra region capture and preserve a California Giant Stonefly(Pteronarcy California Stonefly), both adult and nymph for me...Yes, I'm afraid it's life will have to be terminated. I'd like to get these "real" insects to serve as realistic fly tying models. Pictures are one thing, however, an actual "subject" benefits my dimensional calculations. I'm not even sure when these stoneflys are active ...If anyone can help me I will return the favor...Thank you. Thom
