Bagworm Moths Build Tiny Portable Houses for Themselves That Are Almost Impenetrable

After hatching, the caterpillar of the bagworm moth wastes no time: the larva weaves a silk cocoon around itself and reinforces it with twigs, leaves, and other bits of plants. The result is a small structure that often resembles a tiny house. They provide a safe shell that’s very hard for predators to penetrate, and the locally scavenged building materials give it a natural camouflage against prying eyes.
