Notes: A new carnivorous caterpillar, nicknamed the “Bone Collector,” was recently discovered on the Hawaiian island of Oahu due to its unusual behavior. The “Bone Collector” caterpillar is carnivorous and constructs a protective case using body parts of its prey, like ant heads and fly wings, combined with silk. It is found in a small, isolated mountain forest on Oahu, a habitat threatened by invasive species. The caterpillar’s evolutionary lineage is believed to be at least six million years old, predating the formation of the Hawaiian islands. It feeds on insects caught in spider webs and decorates its silk case with the body parts of its prey.
