Fly fishing for trout in the summer can be challenging. This is why so many of us switch to more logical pursuits such as bass, carp and other warm water species. If I chase trout during the summer it usually takes place through a narrow bite window; early morning, late evening, or middle of the night. Of course as mentioned so many times before there are tons of exceptions; combine that with your schedule, and you may find yourself fishing in the hot mid-day sun. Which brings me to the emphasis of this post.
For trout fishing through the summer, terrestrials rule the day. We know ants make for some fantastic fishing but take a look at the beetle. Opposed to the delicate cast and drag free float used with the ant, beetle fishing begs for and over-powered cast. Why? Beetles have a tendency to fly at high speeds and haphazardly. Often when buzzing around they take awkward dives into the water. More commonly is them falling from trees and plants. When this occurs they make a noticeable plop into the water.
For the summer season, try fly fishing beetle patterns near the banks under over-hanging trees and bushes. Use an overpower cast similar to a tuck cast and let the games begin! I have had trout turn around and swim downstream to take my beetle. They get tuned in to the plopping sound of beetle and other falling terrestrials during the summer months so why not take advantage of it.
Here is a simple pattern I tie that has worked for many years.
