Asiatic rhinoceros beetle (Oryctes rhinocerus)

Kumbang tanduk or Asiatic rhinoceros beetle or coconut rhinoceros beetle (Oryctes rhinocerus) is a species of beetle in Scarabaeidae, horned head, shiny black or dark brown when mature in length 3.5 - 4.5 cm and fat.

The male beetle has a longer and curved rear horn, while the female beetle has a horn in the form of a simple protrusion. The larva is as big as a thumb, gray white and covered with brown hair, a small head is reddish brown in color and eats the decaying stem tree.

The life cycle of these insects varies depending on habitat and environmental conditions. A dry climate and a little food will damage the growth of larvae which can last for 14 months and cause a smaller adult size. The temperature suitable for larvae is 27-29 C with 85-95% humidity.

Pupa is wrapped in materials formed from soil, leaves and twigs. O. rhinocerers live on a variety of trees, including giant sensitive tree (Mimosa pigra), but most like palm species and lay eggs on stems of decaying host plants.

Asiatic rhinoceros beetle attaches to the tops of leaves and stems to absorb fluids which cause damage to young leaf tissue. Horn beetles in general are one of the pest attacks which results in the death of young oil palm plants up to 1.0-2.5 percent.
