This bug wanders around, catches its prey, sucks them dry and then places them on its back as a decoration. Why?
The carcasses function as armour, makes the bug smell different and also camouflages the outline of its body. Also if a gecko were to grab the bug it would end up with mouthful of nasty tasting empty carcasses.
Has a wonderfully dangerous looking “beak” or hardened rostrum for plunging into its prey. This peels back once inside the insect and exposes the mouth parts and injects a toxin.
