Some insects wear the drained corpses of their victims as camouflage armor
Certain assassin bugs pierce prey with a needle-like mouthpart, inject digestive enzymes, and suck out the liquefied insides, then pile the empty exoskeletons onto their own backs, held by sticky secretions. The resulting 'backpack' of corpses camouflages the bug from predators and, in at least one ant-eating species, seems to dampen scent signals that would otherwise alert nearby ants to danger. The habit has been documented across several species, each with a slightly different reason for it.
