A rare carnivorous caterpillar found only on the island of Oahu has surprised scientists with its strange way of surviving. Recently reported in the journal Science, this insect has been named the “bone collector” because it decorates its silk case with the body parts of ants and flies. The caterpillar eats insects caught in spiderwebs and uses their remains to blend in. Experts believe this helps it stay hidden while stealing food from spiders. Researchers from the University of Hawaii at Manoa say that only 62 of these caterpillars have been found in more than 20 years, showing how rare they are. While other native Hawaiian caterpillars use sand or lichen for protection, this species is unique for using animal remains. Scientists believe this insect has been around for over 6 million years—older than the Hawaiian islands themselves. It lives in a small forest area that is now threatened by invasive species. Experts are calling for action to protect the caterpillar and its habitat. The study reminds how special and fragile island ecosystems are and why protecting rare species like this is important.
