October Caddis Wet

Click to Magnify

This is the Great Pumpkin of Western rivers (also found in Missouri streams), a caddis that is almost as large as a golden stonefly. As the name suggests, it emerges in fall.

October caddis larvae build cases of small pebbles and live in moderate to fast flows. As a larva grows, it will abandon its case and build a new one. In the process it may get knocked lose and drift in the current. Even cased larvae sometimes end up in the drift, especially when they migrate to slower water in June and July. Where there is a large population of October caddis, it is not unusual for trout to eat drifting larvae, with or without the case. So a cased caddis pattern dead-drifted near the bottom a worthy strategy beginning a couple of months before the hatch season.

As it nears maturity, the larva will seal off its case and pupate. Many pupae emerge in water that is not very trouty, but a few come out where fish are found. Since this is such a big bug, it doesn't take very many of them to capture the interest of trout, and the fish will be looking for them. When you see adult October caddis around, it's worth drifting a pupa pattern near the bottom.

Adults survive for a couple of weeks after they hatch, and trout can be quite eager for them. The caddis are blown out of bank side vegetation and land on the water, and females return to the water to drop their eggs on the surface. At these times, a dry fly can be very productive. What fly angler can resist this final opportunity of the season to cast a large dry fly?

Tying Instructions

  1. Place the hook in the vise and start the thread behind the eye. Build a thread foundation down the shank to the bend. Bring the thread back to behind the eye.
  2. Tie on a length of burnt chenille down the shank of the hook. Spiral wrap the thread to a point behind the eye.
  3. Wrap the chenille forward and tie off about two eye lengths behind the eye.
  4. Clip off an appropriate amount of deer hair, clean the hair and stack so the tips are equal.
  5. Tie the deer hair behind the eye. Use a bundle wrap so that hair stays on top of the shank. Clip the end.
  6. Select a small amount of partridge and tie on as a beard.
  7. Form a head, whip finish and add a bit of cement.
