ocr: Monarch buttertlies protect themselves by releasing repellent fluids from their wing BUTTERFLY veins, leg joints, and antennae. The foul scent of these fluids warns predators that the butterfly would not make a tasty meal. When butterflies migrate, they strengthen the warning smell by crowding together in large groups. The strong concentration of scent sends predators a powerful warning to stay away. In the Game: See if you can use "strength in numbers" to boost your defenses, as butterflies do.
