Dynastes tityus is known by a number of common names, including eastern Hercules beetle, elephant beetle and ox beetle. [1] It was first given a scientific name by Carl Linnaeus, in his 1763 work Centuria Insectorum, where it was called Scarabaeus tityus; when Linnaeus' genus Scarabaeus was divided into smaller genera, S. tityus was renamed Dynastes tityus.
Dynastes is a genus of large beetles belonging to the family Scarabaeidae.They occur in the Nearctic realm and in the Neotropical realm, from the United States to Brazil; [1] [2] four North American species (including Mexico), three with distributions extending from Central America either north or south, and two species endemic to South America.
Dynastinae or rhinoceros beetles are a subfamily of the scarab beetle family (Scarabaeidae). Other common names – some for particular groups of rhinoceros beetles – include Hercules beetles, unicorn beetles or horn beetles. Over 1,500 species and 225 genera of rhinoceros beetles are known. [2]
The Hercules beetle (Dynastes hercules) is a species of rhinoceros beetle native to the rainforests of southern Mexico, Central America, South America, and the Lesser Antilles. It is the longest extant species of beetle in the world, and is also one of the largest flying insects in the world.
Despite differences in geographic origin and morphology, namely horn length and coloration of the elytra, Dynastes tityus and Dynastes grantii are very similar and it is possible for the two species to produce hybrids. [1] Some scientists believe that the two beetles are actually subspecies given the similarities of the male genitalia. [1] [5]
Xylotrupes gideon, male and females.Museum specimen. Xylotrupes gideon can reach a length of 3.5–7 centimetres (1.4–2.8 in). [7] As usual with rhinoceros beetles there is a great difference between the genders.
