The species, dubbed the "bone collector," belongs to an ancient lineage of moths older than the Hawaiian island of Oahu, which is the only place it's known to live today

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.
