Dyret as the fly is called in Norwegian, is a fantastic caddis pattern from the innovative tier Gunnar Bingen. The fly is called The Animal in English.
Although the fly is not exactly appealing to the fly tiers eye, the trout and grayling love it when a caddis hatch is on. It does not really look like a caddis, but I guess the profile has all the right triggers. Whenever you’ll see swimming pupae its time tie on The Animal.
You’ll clearly see that this pattern is inspired from both the Devil Bug (re-invented by Gary Borger) and the Swedish “Superpuppan” (Lennart Bergqvist). The Animal has the profile from the Devil Bug and the palmered (and trimmed) hackle.
The Animal is a pattern from Rena in Norway. The Rena River is particularly known for it’s Caddis hatches. Several great patterns have come out of these river banks, but The Animal and The Rena Caddis being the two most important.
