Arthropod Class Insecta (Insects)

Caught and photographed in the Upper Midwest on May 12, 2020. I resized my original photo for the website.

I had not fished Bennett Spring for many years and ended up there on Nov 26. I was not very prepared for the stream's entemology, spoke to someone at the flyshop and went with fishing a midge or two and this was very successful. But it was quite obvious that the trout were feeding on the surface or just under and it wasn't a midge. As the day progressed and late afternoon brought sunshine, a hatch of Tiny Caddis(Black) appeared. I had a size 18 but it wasn't dark enough or small enough. A gent who fished the stream regularly gave me a #24 black Elk Hair(or other hair) caddis. The fish took this fly as a dry off the surface. I am hard pressed to ID this fly aside from Protoptila. This, however, is not a marginally temp spring, the water is consistent flow a cold. The description of the Protoptila indicates that this insect is more a warm water insect. The hatch was occurring right at the spring itself. Any ideas?

Again, this was a size 24 fly, and maybe,just maybe, a 26 or 28 might have been the appropriate size for the insect as there were obvious refusals at the surface.

I have just recently started fishing with hellgies and need some info on the best time of year for catching, bait. Any insight will be greatly appreciated

Anyone have experience fishing Trico emergers patterns? I’ve had experience fishing the winged and spinner stage, but haven’t heard of anyone fishing emergers during the early morning female hatch. Anyone used emerger patterns and if so would you might sharing which ones you have found effective?

I'll start with a fly patterns, follow with a bit of what I think I know about Tricos (Entomologists, please offer corrections if needed), and close with a few questions.

I love designing different patterns for Tricos, partly to keep myself entertained, and partly to show the fish something new from time to time. Jason's photos and the opinions of some fussy fish have led me to tie an extra large thorax recently on all my Tricos. My old standby is a parachute tied reverse, with a high vis post over the bend of the hook, and grizzly hackle, with no tails. It's modeled on Al's Trico, which could be found on the Little Lehigh Flyshop website until Rod closed the shop. An internet search may provide images now. It's very visible and fish generally approve. My newest fly is a take off from one of Gonzo's (Lloyd Gonzales) patterns in his book Fly-fishing Pressured Water, and it also shows the influence of Al's Trico. Gonzo ties an upside down Trico on a wide gap hook using synthetic material for the wing. I tie this fly also, and it certainly does catch fish, but I recently tied a version with grizzly hackle, making an oversize thorax and palmering hackle over the thorax to create a full wing. I then clipped hackle from the top of the fly (which becomes the bottom, as this is an upside down fly) so that the fly would sit flat, upside down, on my tying table. A drop of Locktite brush-on super glue on the bare recently clipped thorax after darkening the hackle stem with black marker and the fly was done. (By the way, I put tails on this one to balance it [P.S. Later correction: this pattern doesn't need the tails. I've caught plenty fish now on a tailless version] .) It caught several fish the first time I tried it on a heavily fished stream.

I believe for some, if not most species of Tricos, males hatch at night, females in the morning, and that the spinners fall when the air temperature hits the upper 60's. This generally means that as the season goes on, spinners hit the water later and later. Sometimes by 7:00 am (or earlier) in the early summer, by 10:00 (or later) in the fall.

It's been unseasonably cool in the Northeast the past couple of days, and I would have gone out this morning but for taking my daughter to a midnight showing of The Order of the Phoenix (I just couldn't get up) but I'm wondering if the spinner fall happens later than normal on cool mid-summer mornings like today's. I hope to find out Monday, but am curious if anyone has experiences to share. Also, does anyone have an effective Trico pattern to share? I'm always looking for ideas.
