Dark Green Drake

Overview: The Dark Green Drake (Litobrancha recurvata) is a less common but still significant mayfly species, often overshadowed by its larger Green Drake cousins. These mayflies prefer small, heavily canopied streams, typically found in mountain, spring-fed brook trout streams. The Dark Green Drake is an important hatch for fish, especially in areas where it is more abundant, though it is not as widely celebrated as other mayfly hatches. Its body is dark green, with translucent wings that often appear slightly darker or more opaque than other mayflies. Although these mayflies can be imitated with a size 6 to 8 hook, anglers should consider going one or two sizes smaller, typically using hook sizes 8 to 12 for a more accurate representation.

Nymph Stage: The Dark Green Drake nymph is small to medium in size, typically measuring about 0.75 to 1 inch in length. It has a dark green to brown body with a segmented appearance and a more streamlined shape than larger mayfly nymphs. These nymphs are often found clinging to rocks and submerged vegetation in the cool, fast-moving waters of mountain streams. They are active feeders, crawling along the riverbed before transitioning to shallower waters to emerge as adults. Nymph patterns tied on hooks sized 8 to 12 are most effective. A dead-drift presentation, especially near riverbed structure, can entice strikes from fish targeting these nymphs.

Dry/Dun/Spinner Stage: The adult Dark Green Drake, or dun, measures approximately 1 inch in length. Its body is a dark green color, contrasting with its translucent wings that often appear slightly darker than the wings of the Green Drake. The Dark Green Drake’s emergence tends to be more localized to shaded, mountain stream environments, often occurring during the late afternoon or early evening. Dry fly patterns tied on hooks sized 8 to 12 are effective, though it’s important to size down if fishing in smaller streams. The Dark Green Drake is most effective when fished during its hatch period, providing an excellent surface feeding opportunity for trout in the areas it prefers.
