Terrestrial Imitations - Fly Fishing Yellowstone National Park

Flying Ants: It is impossible to predict when someone may encounter flying ants

Grasshoppers are very plentiful in some places in the park. All of the streams that flow through meadows have lots of grasshoppers. They exist on every stream in the park to some extent. You can catch trout on them in the forest sections of the streams.
The best time to fish the hopper imitations is when the wind is blowing hard. That is not uncommon in the summer afternoons.
The meadows are the best areas to fish them.

Terrestrial imitations are choice flies during the summer and fall seasons. This is something you do not want to be without. From about the first of July until the end of the season, terrestrail insects represent a large part of the trout’s diet.
They are especially plentiful in the many meadows sections of the streams.
