Fly fishing is as much about bugs as it is about fish — and the bugs we depend on are telling us a story about climate change.
Mayflies, stoneflies, and caddisflies — the foundation of trout diets and our favorite fly patterns — are highly sensitive to warming waters, shifting snowmelt, and habitat loss. As the climate changes, these aquatic insects are a wet, buggy canary in the coal mine, signaling big challenges for rivers and the fish we love.
In our Summer issue's Good Fight column, author Chris Wright dives into the science and stakes of climate change for the river bugs at the heart of fly fishing.
