A carnivorous caterpillar discovered on the Hawaiian island of Oahu adorns its silken protective case with the body parts of insect prey. This macabre coat helps them hide from spiders, whose webs make up the caterpillars’ hunting grounds. Bone collector caterpillars are also cannibals, and one is shown eating its fellow species at twice the normal speed.
