After the larval period, transformation into a pupa, and molting, the beetle then emerges as an adult. Much of the life of the larva is spent tunneling through its primary food source of rotting wood. The larval stage of the Hercules beetle will last one to two years, with the larva growing up to 4.5 inches (110 mm) in length and weighing up to 120 grams. ![]() The Hercules beetle is said to be the strongest creature on earth for its size, able to carry 850 times its own body weight.Īs noted above, Hercules beetles are highly sexually dimorphic, with the females generally being larger-bodied but much shorter, as they lack horns entirely. Features of this species are the numerous small black spots on the elytra and the thick hairs on the underside of the thoracic horn. This adaptation is primarily used during fights with other males. This scarab beetle is most noted for its thoracic and cephalic horns, which can grow longer than the body of the beetle itself. One reason for this is that the development of the horns is allometric, as well as sexually dimorphic, and thus not strictly correlated to actual body size it is possible for a female to be much longer, measured from eyes to abdomen, than a male, yet be considered "smaller" simply due to the absence of horns.The Hercules beetles picks up the foe with his horns during fights, flies and slams it down breaking the foes head. However, if the horns are excluded, this species drops considerably farther down in the size rankings. It is the largest of the 6 species in the Dynastes genus, and one of the largest beetles known, being exceeded in length by only two other beetles in the family Cerambycidae, Macrodontia cervicornis (specimens of 170–175 mm are known) and Titanus giganteus (also up to 170–175 mm several 180+ mm specimens are reputed/alleged to exist). Their title is well deserved, with some (exceptionally rare) males reaching 6.75 inches (170 mm) in length. It is native to the rainforests of Central America, South America, and the Lesser Antilles (Clemson University). Here is the entire sheet.The Hercules beetle, Dynastes hercules, is the most famous and largest of the rhinoceros beetles. PressRelease.jsp?CURSOR=116&BV_UseBVCookie=yes> I think you forgot to include the web address. I have never in my life seen a Beetle quite like him. I hope he has a very long and productive life. My husband ended up moving him the next day to a vacant field across the road because he found him on the ground in front of my barn and was afraid my horses would step on him and crush him. Here is a photo of Dynastes tityus on a postage stamp issued in the U.S. These are reportedly the most massive beetles in North America, though some Stag Beetles may be in contention for the record. Some great photos of mating couples of D. Adults are reported to feed off the sap of trees, especially from the Ash family, and to eat figs, while the grubs eat leaf litter and rotten wood. A larger species is found in the West, Dynastes granti. Sometimes they are called Unicorn Beetles or Rhinoceros Beetles depending upon the author, but our latest sources credit the common name to be Hercules, though the scientific name remains the same. We have only received photos of dead ones in the past which can be viewed on our beetle page. ![]() ![]() You have taken a beautiful photograph of a male Hercules Beetle, Dynastes tityus. I have been searching the web trying to identify it but haven’t had any luck. My husband found this on one of our tomato plants this weekend.
