A unique new species of caterpillar found in Hawaii is grabbing attention due to its unusual habit of decorating its silk case with remnants of its prey. This remarkable insect, known as the “bone collector,” is primarily located on the Hawaiian island of Oahu. It feeds on insects trapped in spiderwebs while cleverly camouflaging itself to avoid becoming a meal itself.
Dan Rubinoff, a researcher at the University of Hawaii at Manoa, noted that while there are various carnivorous caterpillars engaging in fascinating behaviors, the bone collector stands out. Its unique method of using ant heads and fly wings in its silk case is unprecedented among Hawaiian caterpillars, which typically utilize more common materials such as lichen or sand for protection.
Experts believe this clever adaptation allows the bone collector to feast on its unsuspecting victims without attracting attention. Steven Montgomery, an entomology consultant in Hawaii, expressed amazement at this caterpillar’s complex case design.
Despite extensive observations over the past two decades, scientists have only identified 62 of these unique insects. This rarity highlights not just their unusual feeding habits, but also raises concerns over conservation efforts, especially as the bone collector occupies a niche within a mountain forest now threatened by invasive species.
Interestingly, the origins of this fascinating caterpillar can be traced back over six million years, predating the Hawaiian islands themselves. As researchers continue to study these incredible creatures, the emphasis on conservation grows ever more critical.
