Assassin bugs are small winged insects that grow to only 6 in. in size and are dark brown in color. They resemble large roaches, but they have a significantly sized stinger on the end of their abdomen. They always travel in male-female pairs. They are never seen in groups larger or smaller than this. Assassin bugs have been known to be released into a political opponent's bedroom by a nefarious noble.
