Green Sparkle Maggot
Unfortunately, this picture doesn't do this size 18 gem any justice. It's very sparkly, and acts as a great attractor fly. This nymph is used either at the bottom of the water column or can be used as a dropper from a dry in some instances to imitate a caddis larva or an emerging caddis. If you flip over rocks in the spring time, as water temps reach the mid 40s, you'll start to see what we call green rock worms, otherwise known as green caddis larva. They can be everywhere! And when they are, it's in your best nature to dead drift these guys through a likely holding spot.
The great thing about this fly is that it's an incredibly easy tie. Good thing because I lose a ton of them on rocks or logs. You simply place an appropriate sized gold bead near the eye of the hook and then make a body of UTC 70 black thread. Apply some green caddis ice dubbing from the bend of the hook to just about behind the bead. Leave room for your peacock herl, and wrap a whole piece in behind the bead. Tie it off, whip finish and your down.
