    Matching the hatch is one of the hallmarks of fly fishing: Identify what food is available to the trout and fish a suitable imitation. Usually, we think about aquatic insects like caddis and mayflies, and if the adult insect isn’t available to fish on the surface we switch to fishing the nymphal form underneath the water. But there are some food sources that never hatch into bugs, yet fish love to eat them whenever they can. One of their favorite is caviar—that’s right, we are talking about fish eggs!

    Some fly fishermen turn up their nose at fishing an egg pattern, likening it to fishing bait (cue Hank Patterson’s rant to Eric Moncada). But really, what’s the difference between imitating a caddis larva rolling along the bottom of the river and an egg? Both are natural food items, and if you know when eggs are in the water you can catch a lot of trout on an egg fly. Of course, while out fishing in the Fall you want to avoid fishing to brown trout that are actively spawning, and it is important to know how to recognize a trout redd and avoid wading through it which could crush eggs. Here is a short ReddUCation Video that BVFF put together that shows what a brown trout redd looks like.

    Just like insect hatches, there are certain times that eggs fish best because they are more available. In November and December rivers are low, brown trout and whitefish are both spawning and believe me, fish notice all of those little balls of protein floating down the river. Brown trout eggs run about 4mm in diameter with whitefish eggs being half that size and their egg colors range from pale to bright orange. Brown trout lay their eggs into redds (nests) and cover them with gravel but mountain whitefish are broadcast spawners, meaning they don’t make a nest but instead discharge their eggs into a gravely riffle. An average trout lays between 2,000 to 3,000 eggs with a large trout laying 4,000 to 5,000 eggs and a typical mountain whitefish releases over 5,000 eggs with large females laying over 10,000 eggs!

    On the Boise River, egg patterns are one of my most productive patterns in late Fall and Winter. Over the years I have fished many different egg patterns but my favorite is the Eggstacy. It is simple to tie and simply out-fishes the others. Eggstacy yarn is available in a variety of colors with my favorite colors being Sockeye and Fl Peach as shown in the photo. Here are instructions for tying the pattern and a video from TightLineVideos on Tying The Eggstacy. Note that when tying a whitefish egg imitation I size down the hook, skip the bead and trim the Eggstacy yarn to make a smaller egg pattern to better match the natural.

    The Western Green Drake is one of the largest mayflys and a favorite summer hatch on the Big Wood and Henry’s Fork. On the Big Wood River they typically hatch in early July, but on low water years the hatch window moves up to late June and on high water years (like this one) the hatch gets pushed out until mid-July.

    Green Drakes belong to the “clinger family” and like faster water than most mayflies—check out the robust legs on the Green Drake nymph shown in the photo! Green Drakes are unusual for mayflys in that instead of emerging from their nymphal shuck at the surface they crawl out of their shucks on the bottom of the river then swim “naked” to the surface. Although the nymphs live in fast water, they migrate to slower edges to emerge, so make sure to drift your dry fly down the slower secondary seams next to the fast water runs.

    It takes Green Drakes time to dry their big wings and fly away and I find emergers fish well. My favorite fly pattern for the Green Drake hatch is Scott Sanchez’s Parachute Midge Emerger. I also have good luck with a dropper of an unweighted peacock soft hackle pattern, which imitates the “naked” Green Drake adult swimming to the surface. Before the hatch, a Prince Nymph is a good bet--I think the white goose biot wings are a good imitation of the nymphal case splitting open.

    Congratulations to BVFF member Bob Harder who recently passed the Fly Fishers International Fly Tying Group Silver Level Award certification. This certification requires a juried examination of six different fly patterns tied by the applicant.

    The FFI Fly Tying Skills Awards Program provides FFI members with the opportunity to develop or reinforce their fly tying skills and test their progress against a consistent, standard at three levels: Bronze, Silver and Gold.

    At Silver level, tyers must be able to tie a wider range of flies, using more complicated materials and techniques to produce more intricate patterns and closer representations of specific prey species being imitated. The degree of consistency and the standard of the techniques applied must be a clear step higher than at Bronze level.

    And yes, that is a lot of thread!!
