}} The brown rhinoceros beetle, Xylotrupes gideon is a brilliant species of large scarab beetle belonging to the subfamily Dynastinae. Subspecies
DistributionThis species is widespread in Indonesia: Java (nomotypical form), Borneo (borneensis), Sunda Islands and Moluccas. DescriptionXylotrupes gideon can reach a length of {{convert|3.5|-|7|cm}}.[3] As usual with rhinoceros beetles there is a great difference between the genders. Males are larger than females. They have two chitinous bifurcated horns, a thick thoracic horn and a smaller cephalic horn, which they use to eliminate their rivals during the mating period.[3] These beetles are shiny dark red, dark brown, or black in coloration. The eyes are located on each side of the head. When disturbed these beetles make a hissing noise, produced by rubbing the tip of the abdomen against the edge the elytra.[4]The larvae develop in decaying vegetable matter and take usually two years in development, the adult beetles live 2–4 months. A female can lay about 20-30 eggs but it depends on the place where they lived .[5] 2- See also
