Hercules beetle

The Hercules beetle is a large rhinoceros beetle native to Central and South America. Males have long, forked horns used in contests for access to mates.

Dynastinae: Dynastinae is a subfamily of scarab beetles that includes rhinoceros beetles. The Hercules beetle belongs to this subfamily of horned scarabs.
Sexual selection: Sexual selection is evolutionary change driven by differences in mating success. Male contests over mates favor traits such as large horns.
Scaling in biology: Scaling in biology examines how physical traits and performance change with organism size. The beetle's size and strength invite comparisons of force across body scales.
Rhinoceros beetle: A rhinoceros beetle is a scarab beetle whose males often bear horn-like projections. The Hercules beetle is one particularly large member of this broader group.
Dynastes tityus: Dynastes tityus, the eastern Hercules beetle, is a rhinoceros beetle native to eastern North America. This close relative is often distinguished from the tropical Hercules beetle.
Dynastes hercules: Dynastes hercules is the scientific species name of the Hercules beetle. This is the species classified under the common name Hercules beetle.
Allometry: Allometry studies how body proportions change with body size. Horn size varies disproportionately with male body size.
Biomechanics: Biomechanics applies mechanical principles to the structure and movement of living organisms. Its horns and load-bearing limbs provide examples of biological mechanics.
Japanese rhinoceros beetle: The Japanese rhinoceros beetle is a horned scarab native to East Asia, especially Japan. It is a familiar rhinoceros beetle with a different range and body form.
Dynastes neptunus: Dynastes neptunus is a large rhinoceros beetle native to northern South America. Its impressive horns make it a close visual counterpart to the Hercules beetle.
