Hercules beetle is the name of several large, strong beetles that live in North America. Male Hercules beetles have long horns that project from the head and front upper part of the body. The horns are curved to meet each other and look like pincers. Males of one species found in the West Indies grow 5 to 6 inches (13 to 15 centimeters) long. The horns may make up more than half of the beetle’s length. The eastern Hercules beetle is found from New Jersey to Pennsylvania and west to Indiana, Oklahoma, and Texas. It is greenish with dark spots. The southwestern Hercules beetle is darker in color and has longer horns. It lives in the southwestern part of the United States.
