Unique Feeding and Camouflage Strategy
The newly discovered "bone collector" caterpillar from Oahu, Hawaii, feeds on insects trapped in spiderwebs and uses their remains to decorate its silk case, serving as camouflage.
This caterpillar's case, made from ant heads and fly wings, is a first among Hawaii's native caterpillars, which typically use lichen, sand, and other materials.
Conservation Concerns and Rare Existence
Predatory caterpillars are rare, with the bone collector species being particularly unique due to its cannibalistic behavior and the use of insect parts for camouflage.
With only 62 individuals observed in over 20 years, the species' origins dating back at least 6 million years highlight its vulnerability, especially against the backdrop of invasive species and habitat loss.
