Fly Fishing Yellowstone - Leeches
Leeches are a major food source for trout in lakes and ponds and some slower moving rivers. As a matter of fact, in any stream or water that holds both leeches and trout, you will most likely find the leeches to be a source of food for the trout. This is especially true in any stream or still water than has a lot of grass and other vegetation.
The Madison River has plenty of them along with many other streams in Yellowstone National Park. Leeches are sometimes called bloodworms. In streams and rivers you will most likely find leeches in the warm, shallow, sheltered waters away from riffles and runs are. These creatures slowly search the bottom looking for something they can eat, so imitations of them should always be fished slowly and in these same types of water.
We think a black Wooley Bugger like our "Perfect Fly" Black Bugger Leech works great. We also have a bead head version of the it.
