The
Hercules beetle,
Dynastes hercules, is the most famous and largest of the
rhinoceros beetles. It is native to the
rainforests of
Central America,
South America, and the
Lesser Antilles (Clemson University). Their title is well deserved, with some (exceptionally rare) males reaching 6.75 inches (170 mm) in length. 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). However, if the horns are excluded, this species drops considerably farther down in the size rankings. 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.
This
scarab beetle is most noted for its
thoracic and
cephalic horns, which can grow longer than the body of the beetle itself. This
adaptation is primarily used during fights with other males. Features of this species are the numerous small black spots on...
