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.

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.

There are other meat-eating caterpillars that "do lots of crazy things, but this takes the cake," the study's author said.
