Peeping Caddis

Created by Hans van Klinken


When a cased caddis feels threatened, the caddis larva pulls its head into the case. But when the caddis drifts in the current, it sticks its head and legs out as if it's on a sight-seeing trip. Often the last thing it sees is the mouth of a trout. This pattern imitates the drifting cased caddis with its head out--hence the fly's name, Peeping Caddis.

The split shot causes the fly to ride upside down, which helps to minimize hang-ups on the bottom.


Cased caddis come in a variety of sizes and colors, depending on the species and local conditions. Gather a few samples from the river and see what colors and sizes are present, then match your imitation to what you find.
