Is it a cocoon? A pinecone? Nope, it’s a bagworm in disguise. These little caterpillars build & wear their own armor made of twigs, leaves, and silk. Seriously, one of nature’s weirdest fashion statements.
What’s a Bagworm?
Bagworms are moths in the family Psychidae. As larvae, they craft camouflaged “bags” from plant materials, which they carry around like little backpacks. Some species never leave the bag, even into adulthood.
Fun Fact: The Females Don’t Grow Wings
In many species, adult female bagworms are wingless, legless, and never leave their bag. Instead mating & laying eggs from inside their twiggy shelter. While male bagworms grow wings and go in search of mates.
Where to Spot Them
Look on evergreen trees, fences, or wooden structures. Anywhere with food and camouflage is where they’ll be! Their bags look like pinecone shards or clumps of dead leaves, but inside? Squishy caterpillar.
Why They’re Cool
Bagworms are insect architects, tailor-making mobile homes from their environment. They’re weird, secretive, & kind of adorable in the best creepy ways.
