I probably shouldnt be sharing this pattern but heres what I use. I have never fished the chrinomidges <sp> at Spinney but I do fish them up at Delanney. The issue at Delanney is this pattern gets chewed up so after many different attempts I think I have developed A pretty sturdy fly.
Size #12 Scud Hook I use Dai-Riki's 135 hooks
Body Black or Red Flex Floss
Rib Fine Silver Wire
Thorax Black Dubbing
Bead Silver Tungsen 3/32 bead
Wing Gray CDC Trimed
I fish both colors at the same time I like to call it the checkerboard collection. I know it sounds like a fish story but I landed over a 100 fish with these 2 flies in an afternoon when the Chirnomidges are going. This is also a good pattern in like a size 18 all year long Hopefully this helps
heres some examples of the chronomids i usually fish...different sizes, ranging from 18 to 12s...red and black are my favorite color. fish them with a s-l-o-w strip, or as a dropper under a large Griffiths Gnat when insects are on the surface. i like using larva lace on these patterns, along with CDC as gills...
I have several patterns similar to the bottom photo that I use. I also tie one on size 12 and 14 Tiemco 200 hooks. The midges are much larger at Spinney and 11-MIle. I also tie one using red and black glass seed beads. They all work at Aurora also!
Memorial weekend is prime time for that hatch so if you see a guy in a green drift boat and a Lab laying on the front seat make sure you come by and say hi. I normally fish the East lake cause well I always catch alot of fish never had a reason to fish the other two lakes.
