i was doing cleanup on my favorite little creek this afternoon for a few hours and thought i would flip some rocks to see what kind of bugs i couldfind. that way i have a better idea of which type of flies would be the most suited for my creek. i found a lot of stonefleis under rocks and wood near the shore, and also.. idk what the real name is but the littla yellow larvae that are stuck to the rock and encased in little pebbles all stuck together. there was a huge abundance of the stoneflies and the larvae but i didn't find much else. so a few questions about this. can anyone give me a general list of flies that best imitate a stonefly nymph besides the stonefly nymph fly and prince nymph?. i already know those will do great. and is it just because it's winter im only finding a few kinds of bugs? id like a little insight on rock flipping and best times to do it and best places too. i know some people that swear by rock flipping to match the hatch and id like to start doing it more myself. im confident it would increase my catch rate .
