The Smoke Jumper fly is a popular pattern on Montana's Bighorn River. The CDC winged emerger is a great all purpose emerger for midge and mayfly hatches. The color scheme of the fly can be altered to imitate the insect you are trying to imitate. Hatches that the Smoke Jumper fly is effective at imitating are midges, Baetis, and Pale Morning Duns.
You can tie the abdomen on the Smoke Jumper with several different materials- peacock herl, turkey biots, micro tubing, or thread with wire.
The wing on the Smoke Jumper is CDC (cul de canard). A high quality CDC makes a big difference on this fly. My preferred CDC is Petitjean Select CDC feathers. Lower quality feathers are not as full and don't make as nice a wing.
