Xylotrupes gideon can reach a length of 3.5–7 centimetres (1.4–2.8 in). 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. 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.
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 . 2-
