I fished wet flies or nymphs more often for panfish when I was younger, and really because I wanted to tie different types of flies. These would be flies that I had seen in magazines & catalogs, so typical trout flies. Now, foam surface flies, or poppers are what I would tie on. I'll toss small streamers too, because of the possibility of a bass hitting it. When I do intend to target panfish, I'm really just fishing for whatever will grab the fly, and with lighter tackle than I use if I'm targeting bass.
The first trip that I ever made to FL, I had intended to rent a boat and fish on one of the lakes near Kissimmee. That week a cold front came thru, with cold temps for FL ( 40's) & with the winds, the marina wouldn't rent out boats, so I was restricted to tossing flies along the canal that lead out to the lake. Not much was happening. I saw Bluegills following a fly I was using, but would turn away at the last moment. I switched flies & tried some others, but got the same results. Finally, I picked a fly out of my box that I had never fished. It was about a size 12, a light dun gray color, and I think the body was made with strips of thin plastic that I had scavenged from something. I think I had tied it in an attempt to imitate grass shrimp for back home (MD) in the tidal creeks. That fly was more of a nymph style, than wet fly, but probably didn't look like any nymph that I had ever actually seen. It was the only fly that produced for a couple of days. As the front had passed, and the weather getting back to normal, I did manage to catch a few small bass on streamers later in the week. But I won't ever forget that small nymph. It was unfortunately a one of it's kind, and something I doubt I could ever duplicate.
