Abstract

Abstract. 1. Predator avoidance mechanisms of adult tiger beetles (Cicindela spp.) were investigated in the Sulphur Springs Valley of southeastern Arizona, U.S.A. 2. The predators were found to be robber flies, lizards, and birds. 3. Effective antipredator characters included body size, orange abdomens, defence chemicals, flight and gregariousness. 4. The number of these five major antipredator mechanisms exhibited by each tiger beetle species varied with habitat. 5. The function and number of antipredator mechanisms was a complex interaction of deterrents; some were effective only in combination and some were characters that each deterred a different type of predator; in several cases, the characters that reduced the probability of attack by one type of predator simultaneously increased the probability of attack by another type of predator.
