Hatches and Trout Flies for the Little Blackfoot River Montana
The Little Blackfoot River has an early season hatch of Skwala stoneflies that takes place during
March and April. Winter stoneflies (Nemoura) are also present these two months.

As with most all the streams in the area, baetis mayflies (Blue-winged Olives) hatch from mid
March until mid June. There is yet another hatch that takes place in September, October and
part of November.

March Brown mayflies hatch starting about the last week of March and through he month of April.
Another March Brown species hatches starting about the last week of August through
September and into the first week of October. Green Drakes hatch from about the middle of
June into the first or second week of July. The runoff may catch part of this hatch.

Pale Morning Duns, or PMDs, as they are called, hatch from about the first of June all the way
through the month of September, depending on the location. This is one of the better mayfly
hatches. The little Mahogany Duns hatch in September and October.

Tricos hatch in the slower water sections of the stream starting about the last week of July all the
way until the first week or two in October. This is one of the better hatches provided you can
handle the small flies.

Golden Stoneflies hatch during July and August. Yellow Sallies hatch from about the first of June
through August. All in all, stoneflies are very important insects in the Blackfoot River.

Several species of caddisflies are present - the Spotted Sedge being the most plentiful. It
generally hatches from the middle of May until the end of August, depending on the particular
species. They are all very similar. Little Short-horned Sedges hatch from about the middle of
June through July.

Different species of Green Sedges hatch from about the middle of June all the way through
September. The Rock Worm, or an imitation of their larva, works great just about all year. The
last big caddisfly hatch is the October Caddis which takes place from about the middle of
September through the middle of October.

Don't overlook terrestrial during the summer. Grasshopper work from about the first week of July
though the month of September. There are also plenty of beetles and ants. There are even
some flying ants, but it is difficult to pinpoint the time you will find them.

Midges hatch throughout the year but are more important during March and April and again in
October when other hatches are slack.

Don't overlook streamers. The river has a good population of Sculpin, minnows and other
baitfish. Streamers work great in low light situations on the Little Blackfoot's brown trout.
