As spring arrives, more and more insects become available for trout to feed on. Knowing the top flies for spring and how to use them is essential for catching more fish consistently when fishing in a lake or river.
Spring is the season that is most dependent on fly selection for fishing. To catch the most fish possible, consider using the top patterns in four major categories: Midges, Caddis, Mayflies, and Stoneflies. These four categories cover nearly three-quarters of the bug life in the spring. However, everyone has different tastes in flies, so these recommendations may or may not be your preferred choice.
<aside> <img src="/icons/daisy_green.svg" alt="/icons/daisy_green.svg" width="40px" /> Caddis | Caddis is my favorite bug because it is a sure sign that winter has passed and warm weather is here to stay. Caddis quickly become an obsession of spring trout, who gorge themselves on every stage of caddis during the spring months. You won't need these flies for March very often, but you'll regret it if you don't have a good assortment come mid-April and May. For best success, fish a dry/adult caddis as the lead fly and drift a nymph or emerger behind it.

<aside> <img src="/icons/daisy_green.svg" alt="/icons/daisy_green.svg" width="40px" /> General Attractors | All forms including nymphs, pupa, emerger, and dries are a major staple in the first month or two of spring until the caddis begin to show up and the trout feed on larger flies that are now moving in numbers that warrant their attention. Hatches start mid morning and can last the entire day if the weather is right. Nymphing during a hatch can be more productive than dry fly fishing and it’s always good to try both during a hatch if one or the other isn’t working.
There are a variety of hatches so it’s best to have a bug seine to collect the insects both above and under the water and match the color and size to what’s in the river. As the water warms up you’ll see what we call a midge-zilla hatch where the midges get downright ginormous and you can throw size #14-16 flies with success. This will be a welcome change to all who are used to fishing size #20 and #22 all winter long.

They are small to medium-sized olive mayflies with dark wings and a dark olive body, typically ranging in size from #12 to #20. These mayflies are likely the most common bug you will see on the water throughout the day, with hatches usually occurring mid to late morning and mid to late afternoon, although this can vary from location to location.
