Meet Your flyBrary
The Flybrary is the most extensive compilation of fly tying information ever produced. With over 500+ tying videos, and detailed tying recipes and pattern information, your tying bench is about to get a major upgrade.

Dry
Highly visible for anglers, and a realistic profile for the trout. Jay Zimmerman is the inventor of this pattern and does a great job of making a pattern that is easy to see and realistic for the trout. You don’t have to sacrifice visibility for realism here and that makes it a highly effective fly that often outperforms more traditional caddis dry fly patterns
Dry
The “tail” on this fly is actaully meant to represent a trailing shuck, meaning that the insect is done emerging but the shuck hasn’t come off yet. That makes an easy meal for trout, and man do they take advantage of it often. The deer hair will keep this fly afloat much better than many of the other comparable patterns.
Nymph
This is a great stonefly imitation for clear water conditions, since it is a bit more realistic than other stonefly nymph patterns out there. The slimmer body with the vinyl rib will help get this fly down to the bottom of the river where the nymphs are. As well as the krystal flash legs also won’t hold the fly up as rubber legs will, so give this fly plenty of line to sink to the bottom.
Nymph
This is a neat little jig nymph that has some great ribbing effect with the two rooster saddle quills. This also allows this fly to be super slim and to drop quickly in the water column. The jig hardware allows this fly to ride along the bottom of the river hook point up, so the snags at the bottom of the hole won’t be as big of an issue.
