“Simple Caddis” is an incredibly effective and clean-looking fly tied by FliesByAspen.
Despite its rather simple appearance, it’s a true "killer" on the water, making it an obvious must-have in any fly box.
This is one of our absolute go-to flies during caddis hatches, especially in the evenings and at night when surface activity increases and fish focus on insects drifting or emerging in the surface film. Simple Caddis is best fished as a dry fly, but it can also perform exceptionally well in slow-moving water where it can drift freely without drag.
We highly recommend experimenting with several variations in your fly box—often it’s the small adjustments that make a big difference when the fish are hesitant. Whether you’re fishing mountain waters, forest streams, or larger rivers, Simple Caddis is a fly that truly earns its place.
Below, we list all the required materials along with tying instructions directly from FliesByAspen, so you can easily tie your own and restock this favorite pattern before your next fishing trip.
