10. Assassin Bug

Assassin bugs are predatory insects. They are experts in catching and feeding on a wide variety of beetles, bees, flies, and caterpillars. The main horror associated with these bugs comes from the fact that they can produce two types of venoms. They use the primary venom to attack their prey and inject it in them. The poison is strong enough to shock the victim and disintegrate its body.

These bugs then feed on these prey by sucking everything out through their proboscis. They also produce another type of venom for larger predators. When an Assassin Bug attacks a large prey like a human, it injects this venom into the skin. This bite causes intense pain and creates s a patch of dead tissue in that area.
