What on Earth is a Caddisfly?
Caddisflies are most well-known for the protective cases they build in their larvae stage. They use small stone, sticks, mud, and other organic matter found on the bottom of waterways. Caddisflies have been around for millions of years, they have even been found in fossils dating back to the Triassic period! With a keen eye, you can find caddisfly larvae in freshwater habitats. Check out the videos below for an up-close look at some caddisflies Kris found in a local creek.
As you can see, caddisflies are aquatic insects during the larvae and pupae stages of their life cycle.

You can create your own caddisfly case at home! Cut out this printable caddisfly larvae and place it inside a toilet paper or paper towel roll. Next, glue anything you would like on the outside of the cardboard roll! Remember, caddisflies use materials found where they live on their cases to camouflage from predators!
Take a look at these caddisflies Kris found in a local creek.
Look at how quickly the caddisflies disappeared once Kris released them in the water. True masters of camouflage!
Here are some other samples of caddisfly cases.
