Speckled Peter
Larva/Pupa










I list the larva stage of life above and certainly trout eat caddisfly larvae but these little caddisflies build
their shelter type cases out of sand and we don't think it's likely the trout eat them, especially with all the
other available food there is in most Yellowstone streams. We feel certain the trout eat the pupae during
the hatch more than any other stage of he Speckled Peter's life.

According to the entomologist, these caddisflies hatch in the water on the surface. They are so small, it's
difficult to see this going on when you are on the water late in the day at the time they hatch. The best time
to catch trout on the Speckled Peter pupa fly pattern in Yellowstone National Park is just before dark.
During the summer months, that's late in the day - as late as 10:00 PM. This is the reason most anglers
miss the best fishing during the caddisfly hatches. At that time of the afternoon and early evening, they are
busy eating dinner or having a drink at their favorite pub or bar. Those that stay on the streams until
there's low light conditions usually are very successful. Not only do they catch more trout, they usually
catch the larger trout.

If it's a heavily overcast day, you may want to start earlier in the afternoon an hour or two prior to dark. You
want to cast the Perfect Fly Speckled Peter Pupa in an upstream direction if it's possible to do so without
spooking the trout. Sometimes, if the water is very smooth, a downstream presentation works better. Either
way you want to fish within a few feet of the banks. We think the pupae swim towards the banks and
emerge near them as opposed to mid-stream. We base that on the fact that's where you will observe the
adults flying and on the water after they have hatched.

We recommend adding a little non-toxic weight to the tippet about six inches above the fly. Don't over do it.
You only want enough to allow the fly to slowly sink to near the bottom. Too much weight will hinder the fly
returning back to the surface in slower flowing water.

If you fish the pupa imitation in smooth water, cast it slightly down and across and allow the fly to sink some
by mending your line. Stop the rod movement and allow the current to bring the fly back to the surface.
That's usually the point at which the trout will take it. You want to continue moving downstream a step or
two at a time to cover the banks.

If you fish in an upstream direction, use an up and across presentation, and mend the line a couple of
times until the fly is downstream of your position. You will want the fly to swing all the way around
downstream of your position. Stop the rod at about a forty-five degree angle and allow the current to return
the fly to the surface.
