How Do You Identify a Fly Fishing Hatch?

Fly fishing is one of the most popular forms of sport fishing and the art of identifying a hatch is a vital skill to have. A hatch is when a particular species of insect emerges from the water and the fish are attracted to them. Knowing what type of hatch is occurring can be the difference between catching nothing and reeling in some trophy catches.

Understand Types Of Insects

The key to properly identifying a fly fishing hatch starts with understanding the types of insects that inhabit your area. Insects such as mayflies, caddisflies, midges, stoneflies, and damselflies can all be found near bodies of water. They come in a variety of colors and sizes, so it’s important to familiarize yourself with the different types.

Observe The Water

Once you know what to look for, you can begin observing the water around you during your next fly fishing trip. Look for areas where insects appear to be hatching or emerging from the water.

They often start out small and then grow larger as they move closer to the surface. The fish will recognize this food source and will begin feeding on them.

Look For Feeding Fish

When fish are actively feeding on a particular type of insect, it’s an indication that there’s a hatch occurring in that area. You can look for tell-tale signs such as finning or rising up in the water which indicate that they’re eating something underneath the surface. Once you spot this behavior, you can use this knowledge to your advantage when fly fishing.


Identifying a fly fishing hatch requires an understanding of what insects inhabit your area and looking for signs such as emerging insects from the water or actively feeding fish. Once you learn how to identify hatches, you are sure to have much more success on your next fly fishing trip!
