You can really spend a lot of time on such a fly. Some folks use woven bodies, a shell back, and go all-out. I’ve done that. But, it makes for a sad moment when I lose such a fly.
So, over time, I’ve really simplified my fly tying. For the Caddis Larva, I like the one in the video at the bottom. It is easy to do and incorporates a cool way to create a dubbing loop, which is a great technique to create extra-buggy bodies (cf. “My New #1 Fly“). I like this Caddis Larva in sizes 16 or 18.
This pattern has a few strike triggers: it’s small, has color contrast, possesses a familiar-looking body color, and has appendages.
