The dementor wasp (Ampulex dementor) was discovered in the Greater Mekong Region in 2014. Its venom blocks the roach's octopamine receptors, which renders it incapable of directing its own movements. The roach can still walk, however, and the wasp will lead it over to a sheltered area before eating it alive.
