The Foam Beetle has become a classic terrestrial fly pattern. Trout eat these fishing flies most often during August and throughout the fall. They float high and are very easy to see. They are also lightweight which makes them a joy to cast on a fly rod. Targeting areas with overhanging trees or downed logs along the river is often a good strategy for this fly. Don’t be afraid of creating a bit of a splash, that’s natural. If you’re building out your terrestrial box for the summer, including a few beetles is always good.
