Green ant

green ants are one of the worlds most deadliest. Of course one ant can be easily killed, but they deliver painful bites and spray formic acid into the wound for more pain. They live in colonies of up to 500,000 ants and when one ant gets injured, it calls it's fellow colony members. As more ants die, more swarms of ants come in until the victim is dead. When it is dead, they feed their brood and themselves with food. You can see two YouTube videos by monster bug wars. Also seen on television.
