Bone collector caterpillar adorns itself in insect body parts

We thought of moths and butterflies as purely innocent creatures, but here’s a shocking revelation: a group of caterpillars—carnivorous ones at that—are taking their Halloween trick to another level by feeding on spider webs while blending in with leftover body parts. Now, researchers from the University of Hawaii have uncovered a new type of these "bone collector" caterpillars, adding a whole new dimension to our understanding of insect-eating insects—and maybe even giving them a reputation to protect.
