The case of a caddisfly—constructed with silk and rocks from the creek bed—serves as a portable protective shelter until the larvae pupates. Recent studies have shown evidence of microplastics in some casings, but this one emerged from a mountain creek in the Rockies. Its case was constructed with argillite, limestone, dolomite, and igneous rocks.
