horns females males adult

Physical characteristics: Adult males have a horn on their heads and midsections and measure 5.9 to 6.7 inches (150 to 170 millimeters) in length. The long horn on the midsection takes up to one-half of the total length. Females lack horns.


Geographic range: Hercules beetles are found in Mexico, Central America, northern South America, Guadeloupe, and the Dominican Republic.

Adult Hercules beetles eat sap and sweet fruits, while the larvae feed on rotten wood. (Illustration by Joseph E. Trumpey. Reproduced by permission.)

Habitat: This species lives in humid tropical forests.


Diet: Adults eat sap and sweet fruits, while the larvae feed on rotten wood.


Behavior and reproduction: They are active at night and are often attracted to lights. Males guard feeding sites that attract hungry females. They will use their horns against other males in battles over females.


Hercules beetles and people: Some people mistakenly believe that they will become stronger and have more energy by eating the horns of the male.


Conservation status: This species is not listed as endangered or threatened. ∎
