Fishing late Autumn hatches of midges (Chironomids) and Blue-winged Olives (BWOs) can be a productive and exciting experience. Here are some fishing tips to keep in mind when fishing these hatches:
- Timing: Both midges and BWOs are prevalent during the latter part of Autumn, although their specific hatching periods can vary depending on your location and local conditions. It’s essential to do some research or check with local fly shops or fishing reports to determine the most active times for these hatches in your area.
- Understanding the insects: Midges are small flies that belong to the Chironomidae family. They come in various colors and sizes, but most are quite small, often ranging from size 18 to 24. Blue-winged Olives, on the other hand, are small mayflies with olive-colored bodies and distinctive grayish-blue wings. They are typically larger than midges, ranging from size 16 to 22.
- Fly selection: When imitating midges, choose patterns that match the size and color of the natural insects. Popular midge patterns include the Griffith’s Gnat, Zebra Midge, and RS2. For Blue-winged Olives, patterns such as the Parachute Adams, Comparadun, and Sparkle Dun can be effective imitations.
- Presentation: Midge and BWO hatches often occur in calm or slow-moving water, such as can be found in tailwaters. Approach the water cautiously to avoid spooking the fish. Use delicate presentations and make sure your fly drifts naturally with the current. Both midges and BWOs can be found in the surface film, so fishing with dry flies or emergers can be successful. However, be prepared to switch to nymphing techniques if the fish are not actively feeding on the surface.
- Observation: Take time to observe the water and look for any signs of rising fish or insect activity. Watch for trout feeding on the surface or any emerging insects. Keep an eye out for any midge clusters. This information can guide your fly selection and presentation.
- Weather and water conditions: Fall weather can vary, so pay attention to the conditions on the day you’re fishing. Both midges and BWOs prefer overcast and cooler days, as they tend to hatch more actively under these conditions. Windy days can also trigger better insect activity. Additionally, water temperature and clarity play a role, as fish tend to be more active and willing to feed in optimal conditions.
Remember that autumn fly fishing can be unpredictable, and fish behaviour can vary from one location to another, or one day to the next. It’s always helpful to gather local knowledge, adapt your techniques as needed, and be prepared to experiment with different fly patterns and presentations until you find what works best for the specific situation you encounter on the water.
