Inch Worm (Moth Larva)

Terrestrial insects are insects that are born on land and spend their life on land. They only get into the water accidentally by falling, flying and landing or being washed into the water by heavy rains.

The inch worm larvae are also called loopers, spanworms and measuring worms; and they are green in color with some being a slight yellowish in color. When they are ready to pupate the larvae will suspend several inches from limbs on a silk thread. When they are suspended over water they often wind up falling into the water where they become
available for the trout to eat throughout the summer.

Should you be on a stream where there is no hatch occurring, look for these green inch worms hanging from the trees, If present, it would be a good time to try the Perfect Fly inch worm pattern. This pattern may be effective even in the event that there are no inch worms present because it resembles the free living caddis larvae (Rock Worms) and some of the net-spinning caddis larvae as well.
 

Presentation:

Fish the inch worm pattern near the banks where there are tree limbs and bushes. It can be fished with or without adding weight. Rig the inchworm larva pattern in tandem with a large fly like a hopper fly as an indicator. Tie the inch worm on at a depth to match the water where you are fishing. Of course you can also use a strike indicator in place of the attractor fly. If you choose not to use an attractor or indicator you can detect the strike simply by carefully watching your line and leader.
