The Caddis Biot Wing | Fly Patterns For July Heat

(all images shot with 10X power macro lens feel free to click for details)

The Hanak 300 BL hook provides a great foundation for the adult caddis fly.

From the end of June through August I tie many variants of caddis adults. This

is one that has proven itself over the years. I tie my biot wing Mid Summer Caddis in 

sizes 14 and 16 and I adapt the same materials on a TMC 531 and tie it down to a size 20. 

Using biot wings on my adult patterns started back in 1999 and since then I have been dying

all of my turkey biots to match the seasonal shades of color throughout the summer months.

The body is wrapped yellow tan peacock quill fashioned with yellow tan micro knotted pheasant tail legs. The underwings are two dusky gray CDC feathers covered by the main biot wing.

Dubbing collar is a combination of muskrat, squirrel, and UV all mixed together

and spun using a small split thread section of tan Pearsalls Silk. Antennae are two fibers of

lemon wood duck flank.
