The information and video below are set in Marion County, but the scenery is typical of the entire Sequatchie Valley.
TN Wild Side – Sequatchie Caddisfly
Anglers refer to it as “stick bait,” most people don’t see it, and biologists believe its future is very uncertain. The Sequatchie Caddisfly is one of those small, amazing animals that might be an afterthought to many. In truth, it plays a critical role in the ongoing health of the entire Sequatchie Valley, one of Tennessee’s most beautiful natural areas. As humans have intruded into its world, the Sequatchie Caddisfly has lost most of its population and living area. Today, it’s confined to a small corner of its original habitat. That’s where we find Wild Side Guide Alan Griggs exploring the unusual relationship of a cave, a spring, and a tiny animal that lives there.
