Fun Animal Facts: Meet the Rhinoceros Beetle! By Kymber Roldan
As our family gathered at a home in Lagrange Texas for Christmas 2024 my granddaughter Dahlia discovered a Rhinoceros beetle. Her mother brought the large beetle in to the house for her and Dahlia was jumping up and down with excitement.

After showing off her newfound prize, she added him to her terrarium where he will live out his remaining days. I knew when I saw him he was not very long for this world but what a treasure for a curious little girl. This experience influenced this posting.
Rhinoceros Beetles
Common names: Rhino beetle, Hercules beetle, unicorn beetle, or horn beetle.
There are 1500 species with 225 genera in this sub species.
Rhino beetles are a subspecies of scarab beetles (Scarabaeidae). They are among some of the largest beetles living. Sizes range from 2-3 inches (5-7 cm) all have horns originating from their central head and forming from mid thorax pointing forward. They use the horns for digging, defense and fighting during mating. Horn size is a representation of physical health of the male.
Rhino beetles hatch from eggs, developing in to a larval stage, they can stay in this stage for years prior to developing in to pupae and then emerging in their final beetle form to reproduce and continue the cycle of life.
Rhinoceroses beetles as pets.
In Asia Rhinoceros, beetles are popular pets. They are easy to keep, clean pets that do not smell and are simple to feed. In Asia, some male beetles often are used for entertainment. With the aid of a female beetle, they set two males up for fights and often people gamble on who the winner will be. Winning beetles are highly prized.
Pest Beetle control:
All stages of Rhino Beetle: Rats, Ants, Pigs and other beetle species will eat beetles and their larva.
2 imported diseases threatening Rhino beetles: Fungus Metarhirium Anisopliae and Oryctes Virus .
Mostly used for control of coconut beetles in Hawaii. Formerly known as Rhinoceros Nudivirus Oryctes. Discovered in Malaysia in 1963, used as a biological control of Rhinoceros Beetles in Asia and the Pacific Islands. This virus causes the disintegration of body fat and causes adults to stop eating. It is spread beetle to beetle, intrahemocoelic inoculation, and fecal-oral contact during mating. Currently it is found in tropical regions of Africa, Asia, USA and Oceania.
Metarhirium Anisopliae, Strain F52 infects insects, primarily beetle larva. . m. anisopliae, grows naturally in soils throughout the world and causes disease in various insects by acting as a parasitoid. This has been a helpful ânaturalâ defense against beetles for non-food plants, however; recently reported cases of human and feline infections bring its use in to question.
