Maggie Heumann of Trout Unlimited breaks down the fascinating world of entomology - the study of insects, and explains why understanding aquatic insects is essential for fly fishing success.

You'll learn what makes an insect an insect, how their unique life cycles and adaptations influence fish behavior, and how this knowledge can help you better match your flies to what fish are naturally feeding on. Covering everything from basic insect anatomy to the key aquatic species important to anglers, this course will give you a solid foundation to read the water more effectively, choose the right fly patterns, and ultimately catch more fish. Whether you're new to fly fishing or looking to deepen your understanding of the bugs trout eat, this course will make entomology approachable, fun, and directly applicable on the water.
