Hatches and Flies for Straight, Winter, Panther, Indian and
Obsidian Creeks (YNP) Wyoming
The aquatic insects found in the these little brook trout streams are very plentiful and
consist of several species of caddisflies, mayflies, stoneflies and midges.
Blue-winged Olives, Baetis species, hatch from opening day until the end of the month of
June. The are bi-brooded and will hatch again staring about the first of September and
lasting until the season ends.
The Spotted Sedges usually start hatching about the middle to the last week of June.
These caddisflies will hatch off and on until the middle to the end of August. The Green
Sedges hatch starting about the first of July and last until the middle of October. The Little
Short-horned Sedges will hatch throughout the month of July. There are some Long Horn
Sedges, that will hatch the last two weeks of July. You will also find plenty of Little Brown
caddisflies that hatch the last two weeks of July and the first two weeks of August.
The PMDs, or Pale Morning Duns, are the most important mayflies on these creeks. They
start about the middle of June, depending on the weather and last all the way to the middle
of August. The hatches and spinner falls are both important. The Brown Drakes start about
middle of June, and hatch for a month.
A few Yellow Sallies, or Little Yellow Stoneflies, hatch from about the middle of July for a
month or longer in the fast water areas of these streams.
Terrestrial insects are very important trout food on these small streams. Imitations of
grasshoppers, ants and beetles will catch trout from about the first of July until the middle
to end of September. The meadows are especially great for hopper fishing. Don't overlook
the flying ants. They can swam and fall on the water anytime during the summer so be
ready for them if they do.
We have "Perfect Fly" imitations of every insect that hatches in Yellowstone National Park.
Many of our flies were developed there. If you haven't already done so, we encourage you
to give them a try. The not only are the most realistic flies you can buy, they are the most
effective at catching trout. We also have numerous generic and attractor flies at very low
prices that will work for the small brook trout.
