Description
Caddis Worm, a nymph pattern that imitates the larval stage of a caddisfly. Caddisflies are a staple food source for fish in many rivers and streams. This particular fly, with its segmented, worm-like body, is designed to be fished below the surface, where it mimics a caddisfly larva drifting in the current.
Type of Fly: Nymph (specifically, a caddisfly larva imitation).
Target Fish: This is a very effective pattern for a wide range of freshwater fish, especially trout (including rainbow, brown, and brook trout), grayling, and even some species of char.
When to Fish: The Caddis Worm is an excellent year-round pattern. It is especially useful during caddisfly hatches, or during periods of high water or runoff when insect larvae are dislodged from the stream bottom and become available to feeding fish. It can be fished successfully at any time of day, but is particularly effective in the morning or late afternoon.
Saltwater or Freshwater: This is a freshwater fly.
Best Fishing Locations: This fly is particularly effective in rivers and streams, especially in riffles, runs, and the stony bottoms where caddisflies thrive. It can also be used in lakes and ponds, fished along the bottom near weed beds or rocky areas.
