Chasing the Buzz: A Guide to Cicada Fly Patterns on the Green River
As a fly fishing guide and outdoor writer for over a decade, I’ve witnessed some incredible hatches, but few compare to the explosive feeding frenzy that occurs during the cicada hatch on the Green River in Utah and Colorado. The sheer volume of these insects emerging from the ground creates a unique opportunity for anglers, and knowing the right cicada fly patterns can make all the difference. This guide will cover everything you need to know to successfully fly fish cicada hatches, from understanding the lifecycle to selecting the best flies and techniques. We’ll focus specifically on the Green River, a renowned tailwater fishery that consistently delivers exceptional cicada fishing.
Understanding the Cicada Hatch & Why It's Special
Cicadas aren’t annual events like mayflies or caddisflies. They operate on longer cycles – 13 or 17 years for periodical cicadas, and 2-5 years for annual cicadas. The Green River primarily experiences hatches of annual cicadas, meaning you can anticipate them most summers, though the intensity varies year to year. The timing is heavily influenced by water temperature and rainfall. Generally, the peak hatch occurs from late July through August, but it’s crucial to check local fly shop reports for up-to-date information. (National Park Service - Green River Fishing)
What makes the cicada hatch so special? Trout absolutely love them. These large, protein-rich insects are a significant food source, and trout will often abandon their usual feeding habits to aggressively target cicadas. This leads to surface feeding that is both visually spectacular and incredibly rewarding for anglers. The hatch isn’t subtle; it’s a full-on assault on the senses, with the buzzing of cicadas filling the air and trout actively leaping for them.
The Cicada Lifecycle: From Nymph to Fly
Understanding the cicada lifecycle helps you anticipate the hatch and fish effectively. Cicadas spend most of their lives as nymphs, living underground and feeding on plant roots. When conditions are right, they emerge, climb onto vegetation, shed their nymphal skin, and become winged adults. This emergence happens over several weeks, creating a prolonged hatch. The spent (dead) cicadas also provide a significant food source for trout, so don’t overlook patterns that imitate these.
Essential Cicada Fly Patterns for the Green River
Choosing the right cicada fly patterns is paramount. While trout aren’t particularly picky during a heavy hatch, having a variety of patterns in different sizes and colors will increase your chances of success. Here’s a breakdown of some essential flies:
- Foam Cicadas: These are incredibly buoyant and durable, making them ideal for fishing fast currents. They come in various colors, including tan, brown, and olive.
- Popper Cicadas: These create a lot of surface disturbance, attracting attention from distant trout. They’re best used in slower water or when you want to provoke a strike.
- Realistic Cicada Imitations: Flies tied with deer hair or synthetic materials that closely resemble the natural insect. These are effective when trout are being selective.
- Spent Cicada Patterns: Flies that imitate dead cicadas, often tied with a more subdued color palette and a slightly sunken profile.
- Parachute Cicadas: A newer style that offers a more subtle presentation, especially effective when fish are rising consistently but ignoring more aggressive patterns.
Size matters! Cicadas on the Green River typically range from size 8 to 14. Having a selection of flies in these sizes is crucial. Don’t be afraid to experiment. (REI Expert Advice - Fly Fishing Cicadas)
Recommended Fly Selection for the Green River Cicada Hatch
| Fly Pattern | Size | Color | Best Conditions |
|---|---|---|---|
| Foam Cicada | 8-12 | Tan, Brown | Fast Currents, All Day |
| Popper Cicada | 10-14 | Olive, Brown | Slow Water, Cloudy Days |
| Realistic Cicada | 8-10 | Natural, Olive | Selective Trout, Clear Water |
| Spent Cicada | 12-14 | Dark Brown, Grey | Late Afternoon, Calm Water |
Techniques for Fly Fishing Cicada Hatches on the Green River
Successfully fly fishing cicada hatches requires adapting your techniques. Here’s what I’ve learned over the years:
- Presentation is Key: Unlike delicate mayfly presentations, cicada fishing often benefits from a more aggressive approach. Don’t be afraid to “bang” the fly on the water to create a disturbance.
- Retrieve Speed: Experiment with different retrieve speeds. Sometimes a slow, deliberate retrieve works best, while other times a faster, erratic retrieve is more effective.
- Dead Drift with a Twist: Try dead drifting a spent cicada pattern, but occasionally twitch it to imitate a struggling insect.
- Focus on Structure: Trout will often congregate near structure, such as rocks, logs, and overhanging vegetation, to ambush cicadas.
- Look for Rises: Pay attention to where trout are rising. Cast your fly slightly upstream of the rising fish and let it drift naturally.
Don’t be afraid to try different things. The Green River is a dynamic fishery, and what works one day may not work the next. Observe the behavior of the trout and adjust your tactics accordingly.
Gear Recommendations for Cicada Fishing
While you can use your standard trout setup, a few adjustments can improve your success. I recommend:
- Rod: A 9-foot, 6-weight fly rod is a good all-around choice.
- Line: A weight-forward floating line is essential.
- Leader: A 9-foot, 3X or 4X leader is a good starting point.
- Tippet: Use 3X or 4X fluorocarbon tippet.
- Floatant: A good quality floatant is crucial for keeping your fly afloat.
Safety and Ethics on the Green River
The Green River is a beautiful and fragile ecosystem. It’s essential to practice responsible angling and minimize your impact. Always follow these guidelines:
- Check Regulations: Be aware of the current fishing regulations for the section of the Green River you’re fishing. (USDA Forest Service - Green River)
- Practice Catch and Release: Handle fish carefully and release them quickly.
- Leave No Trace: Pack out all trash, stay on established trails, and avoid disturbing vegetation. (Leave No Trace Center for Outdoor Ethics)
- Respect Other Anglers: Give other anglers plenty of space and avoid wading through their fishing areas.
- Be Aware of Weather Conditions: The weather in the mountains can change rapidly. Be prepared for all conditions.
Beyond the Cicada Hatch: Exploring the Green River
The Green River offers excellent fishing opportunities year-round. If you’re planning a trip, consider exploring other hatches, such as the Blue Wing Olive hatch in the spring and the Trico hatch in the fall.

The Green River cicada hatch is a truly unforgettable experience. By understanding the lifecycle, selecting the right cicada fly patterns, and employing effective techniques, you can maximize your chances of success and enjoy one of the most exciting hatches in the West. Remember to fish responsibly and respect the environment, ensuring that this incredible fishery remains pristine for generations to come.
