Appearance The rhinoceros beetle is named for the large horn protruding from the head of the male. One protrudes from the front of the head and the other comes from the middle of the thorax. By moving the head they can pinch the two horns together. Females lack the horn and instead have a flat head making them easy to tell apart. As an insect their body is divided in to three sections the head, thorax and abdomen. Six legs sit on the sides of the body. At the end of the legs are small claws which help them hold on to items. Across their body they are colored black. Protruding from the front of their head are antennae which are used to feel the world around them. Their body can reach a length of up to 7cm (2.8in) long making them among Australia’s largest beetles. Diet Throughout their life the rhinoceros beetle is a herbivore. As an adult they will feed on soft fruits and the bark of young shoots. Large gatherings may occur at good food sources and these gatherings are thought to be part of their breeding behavior. Larva live in pulpy wood which is their main food source along with leaf litter and mulch. The larva assist the break down of timber in to feed. Range In Australia this species can be found in New South Wales and Queensland. They are also found in New Guinea. Habitat Naturally these animals are found in rainforests. As humans have expanded their range these animals have adapted to live near people and can often be sighted near bright lights in car parks or at pe...

( Scarabaeus rhinoceros Linnaeus, 1758 The Asiatic rhinoceros beetle, coconut rhinoceros beetle or coconut palm rhinoceros beetle, Oryctes rhinoceros) is a species of O. rhinoceros attacks the developing Biology [ ] This large species has an average length of about 33 to 40mm. Adults are dark brown to black in color with shiny dorsum. Head with a prominent horn. Male has longer horn than the female. Male is characterized by a rounded, shiny terminal abdominal segment whereas female has a relatively hairier 'tail'. There are two tubercles on the thoracic ridge. Eggs [ ] Adult female lay yellowish-white oval eggs which are about 3mm in diameter. Eggs are typically laid inside rotting vegetative matter. After one week, they swell and later hatch within 11 to 13 days. Larva [ ] Grub stage undergo three instars before becoming a pupa. Grubs are yellowish-white where the third instar grow to 60 to 100mm in length. Cranium is dark brown, with many round pits. There are minute setae on cranium. Thoracic spiracles are about 1.85 to 2.23mm long. Respiratory plate consists with small, round to oval holes. Thoracic spiracles are larger than abdominal spiracles. Pupa [ ] Pupa is yellowish-brown with about 50mm in length. There are horn-shaped protuberances on the anterior surface. Economic importance [ ] O. rhinoceros adults are In 1964, accidental introduction in some countries, and the perceived threat led to a special Control measures include the use of cultural methods, such as cro...

The male Rhinoceros beetle is best identified by the presence of a long, black horn protruding from its head. This horn is used to keep other males away from a female. Females do not have a horn. The rounded pronotum is large. Both sexes have faint ridges on the black elytra. Dark red hairs stick out from under flake-like extensions on their legs. While larger than most beetles, Rhinoceros Beetles are smaller than the Rhinoceros Beetles are not known to bite and are considered somewhat friendly. Adults may eat dead roots, and larvae are believed to feed on dead and decaying plant matter on the forest floor. This particular species of Rhinoceros Beetles is found in woodlands west of the Rocky Mountains. Ash tree roots are a favored food source for larvae. Adults are mostly active at night and may be attracted to lights.©InsectIdentification.org Known Diet of the Rhinoceros-Beetle * MAP NOTES: The territorial heat map above showcases (in red) the states and territories of North America where the Rhinoceros Beetle may be found (but is not limited to). This sort of data is useful when attempting to see concentrations of particular species across the continent as well as revealing possible migratory patterns over a species' given lifespan. Some insects are naturally confined by environment, weather, mating habits, food resources and the like while others see widespread expansion across most, or all, of North America. States/Territories shown above are a general indicator of are...

The Hawaii Department of Agriculture is asking Kauai residents to Breeding grounds for the beetles include green waste, compost, mulch, trimmings, trees, and decaying stumps of palms and plants. Two coconut rhinoceros beetles – one live and one dead — were The department said early detection of coconut rhinoceros beetle populations is key to eradication of the serious pest of palm trees, primarily coconut palms. The state and partner agencies have mounted a response, but are asking Kauai residents to help. “It’s critical that we catch any possible breeding areas immediately to try and stop the beetle’s spread on Kauai,” said Sharon Hurd, chairperson of the state Ag Department, in a news release. “We need everyone’s eyes to look out for possible infestation sites and to report it.” Kauai County, meanwhile, has closed the green waste facility at the Lihue Transfer Station until further notice to assist in surveying of the area for the beetles. Reports of possible CRB infestation should be sent to the CRB Response Team at 808-679-5244 or

Each Wednesday, One Earth’s “Species of the Week” series highlights a relatively unknown and fascinating species to showcase the beauty, diversity, and remarkable characteristics of our shared planet Earth. Dynastinae, Rhinoceros or Hercules beetle… no matter what you call it, this insect is a force of All rhinoceros beetles are herbivorous, feeding on fruit, nectar, and tree sap that they tap with their horns. Such a gentle diet for a giant! The larvae eat decaying plant matter. Most Rhinoceros beetles are black, gray, or greenish in color, and some are covered in soft hairs. Though almost mythological in appearance, they are found on every continent on Earth except Antarctica. In the Rhinoceros Bettle. Image credit: Creative Commons The male rhinoceros beetle is proudly posts a long, intimidating horn on its head that curves up, and is used for mating ritual fights. Additional, shorter horns project out from his head. Females are smaller and do not have horns. Females lay about 50 eggs, which hatch into larvae. Longevity varies among species, but a typical lifespan is one to two years, with much of that time spent in the larval stage. When disturbed, or before mating with a female rhinoceros beetles produce hissing squeaks. These sounds are not vocal, but produced when the beetle rubs its abdomen and wing covers together. This rhinoceros can fly short distances, although its heavy body makes for a bumpy and brief ride. Good thing, because although these insects are harml...
