Reduvius personatus or the masked hunter is an insect belonging to the assassin bug (Reduviidae) family. The name is because its nymphs camouflage themselves with dust. The masked hunter is a predator of small arthropods, including woodlice, lacewings, earwigs, and bed bugs. Masked hunters do not feed on human blood, but can bite humans in self-defense when mishandled. The bite can be extremely painful, but masked hunters are not known to transmit any diseases and medical attention is rarely needed.
