Interesting facts about the rhinoceros beetle

  • The rhinoceros beetle or Oryctes nasicornis is one of the leaf horn beetles and is considered the largest of the domestic representatives of this family.
  • He is originally from the countries of the Mediterranean. Its current range extends from North and West Africa across the Canary Islands and Central Europe to southern Scandinavia. The rhinoceros beetle is also found in western Siberia and in central and eastern Asia.
  • He lives primarily in areas near human settlements, where he prefers to stay in parks, gardens, compost heaps, sawmills or straw storage.
  • The Rhinoceros beetle owes its German name to the bent, strongly pronounced horn, which only the males carry in the middle of the top of the head. The females have only a small inconspicuous hump at this point.
  • The rhinoceros beetle reaches a total length of two and a half to four centimeters and wears a shiny, black or dark reddish brown colored tank.
  • The underside and legs show a dense, bright orange-red hairline.
  • The white and cylindrical larvae of the rhinoceros beetle are comparatively large and remind of their shape of a curved C.
  • They require a certain temperature for their development to the Engerling, which they find in compost heaps by the decomposition processes of the organic material.
  • For a larva to grow into a beetle, its habitat must remain untouched. However, this is rarely possible by the action of human hands.
  • The development of the larva to adult Engerling, which reaches a length of up to twelve centimeters, takes between three and five years to complete. During this time she feeds on decomposing sawdust, wood and other cellulose fibers.
  • After the mature beetles appear in May, they only live between four and six weeks long.
  • The eating habits of the adult beetles are not clearly researched until today, but scientists suspect that they primarily eat leaking tree juices.
  • Only the larvae have predators with various types of dorsal wasp, whose larvae use the grubs as a source of food.
  • The rhinoceros beetle is protected throughout the German-speaking area.
