A new carnivorous caterpillar that wears the remains of its prey has been dubbed the “bone collector.” The odd insect is only found on the Hawaiian island of Oahu. It creeps along spiderwebs, feeding on trapped insects and decorating its silk case with their body parts.

Adorned in their macabre attire, the caterpillars can safely navigate spiderwebs undetected. They use their camouflage to feed on trapped prey: both living and freshly dead. Bone collectors will target and kill weakened or slow-moving insects, even hunting and cannibalizing their own kind. In each spiderweb, there can only be one.
