Milkweed Assassin Bugs mimic an abundant herbivore gaining an advantage in its method for food-hunting.
A Milkweed Assassin Bug is red and black in almost the same places as Large Milkweed Bugs. This makes it easier to for the assassin to walk among its prey. While Large Milkweed Bugs eat seeds and plant stems, leaving other insects alone, Milkweed Assassin Bugs bug killers. Mimicking such a 'friendly' bug allows the Milkweed Assassin to tread closer to unsuspecting insect prey. They quickly attack an insect and repeatedly stab it with a large fang. This fang kills the insect, allowing the Milkweed Assassin to feed on its insides. This same fang is also able to stab people, inflicting a very painful wound.
Look for Milkweed Assassin Bugs on milkweed plants as well as flowers. It has a longer head and more slender 'waist' than its doppelganger.
