Slight Change in Hatches Notice I am dropping the Hendricksons and Red Quills from the hatches that may occur. I'm adding "inch worms". This makes a slight change in the 'Flies You Need Now".
Green Sedge (Caddisfly) - Larva These are the Rhyacophila species of caddisflies that are common in the streams of Great Smoky Mountains National Park. The larvae of the Green Sedges are called Rock Worms and sometimes Green Rock Worms. .
This is one of the free-living types of caddisflies. The larvae of these caddisflies do not build cases that they carry with them. You will find them in the riffles and runs where they live up until they hatch into moths. They prefer fast water and require lots of oxygen.
You can catch trout throughout the season on imitations of the larvae or rock worms. They are available for the trout to eat most of the time. They can get down between and under the rocks of the stream's bottom but they are often exposed. They are most exposed when they are eating.
There are numerous species of these caddisflies. In any one stream there may be most all of the below species. These various species will usually hatch at different times. Some may be fairly prolific and others may be sparse. You should keep your eyes out for a hatch of the Green Sedges anytime from now until about the first of July.
The large number of species is one reason for the long hatch period. Below is a list of the species that are found in Great Smoky Mountains National Park. There's very, very little difference in them from the standpoint of imitating them. They are almost identical and a magnifying glass is necessary to distinguish them in most cases.
