Dermestid beetles, a species of beetle, have been used for centuries to clean bones of all types, particularly those that are difficult to dissect by hand. They are known for their ability to consume tissue and remove skeletal calcium from bones, making them an effective method for cleaning bones. Various parts of the skeleton of rats were compared with respect to their dry weight, ash weight, and calcium content when the bones were cleaned by dermestes. After the beetles remove all soft tissues, the material should be cleaned with ammonia to remove fat and beetle eggs. The skeleton or bones are then dried at 40°C.
Beetles are faster than maceration and provide better control over the cleaning process. They are also used to remove articular cartilage from small skulls, especially rodents. A new method for removing articular cartilage using dermestid beetles and 3D model registration ensures that cartilage thickness on the articular surface of long bones is maintained. This method is DNA-based and is considered sacred in Ancient Egypt.
Dermestid beetles are fast and fastidious eaters, capable of picking a carcass clean in just days, leaving even the most delicate bone structures intact. They have been employed by museums for over 100 years and are often used for identification and display purposes in museums. Forensic scientists use them to clean bones from crime scenes, museum curators and taxidermists use them to clean specimens, and flesh-eating beetles help clean bones for taxidermy.

What Is A Skin Beetle Used For?
Commonly known as skin beetles, carpet beetles, or flesh-eating beetles, Dermestid beetles belong to the family Dermestidae and are primarily utilized for cleanly removing tissue from bones. These beetles consume the soft tissue of carcasses, resulting in a mostly intact skeleton, and they are considered beneficial scavengers that feed on dry animal remains. Among various methods for cleaning bones, such as using chemicals or heat, these beetles have become a popular choice, particularly in the fields of taxidermy and forensic science.
The species most commonly employed for taxidermy is Dermestes maculatus, also referred to as skin or hide beetles. Dermestids comprise at least 500 species globally and are significant in forensic entomology, as they are often among the last to colonize decomposing remains, assisting in estimating the time of death. They can reach sizes of 1-12 mm and have oval-shaped bodies.
These beetles play a dual role; not only are they used in skeletal preparations, but they also have implications in forensic investigations. In addition to their use in taxidermy and by museums to clean animal skeletons, Dermestid beetles are recognized as pests in households, where they may infest food stores. Despite their scavenging nature, these beetles can also feed on fresh meat if the colony size is sufficient to perform the task effectively.
Overall, Dermestid beetles are vital not only for their ecological role but also for their applications in various scientific fields, including law enforcement and natural history curation.
Do Dermestid Beetles Clean Bones?
Museum curators and wildlife officials utilize Dermestid beetles for efficient and safe bone cleaning. Thorvald Holmes, collections manager at HSU's Vertebrate Museum, endorses these beetles for tissue removal, highlighting them as superior to other methods that risk damaging bone structures. Dermestid beetles are adept at consuming soft tissue and can thoroughly cleanse bones without causing fractures or separation.
Known colloquially as skin or carpet beetles, these insects belong to the family Dermestidae and are crucial for tasks like taxidermy, where maintaining the integrity of skeletal structures is essential.
For successful skull cleaning, a colony of at least 300 beetles is necessary, with larger specimens requiring up to 5, 000 larvae. Their rapid eating habits can leave bones pristine in mere days. Complications arise with other cleaning methods like boiling, which can compromise the structure of delicate bones. Dermestid beetles, especially their larvae, excel in cleaning tiny bones due to their meticulous nature.
These beetles not only facilitate easier specimen tracking, but they also engage in their natural behavior by consuming remaining flesh, presenting a win-win for taxidermists. To begin with this process, proper care and maintenance of the beetle colony are crucial for optimal performance. The use of Dermestid beetles in forensic work and taxidermy highlights their important role in the preservation of vertebrate remains, serving as an effective alternative to manual dissection methods.
When Were Beetles Invented?
The Volkswagen Beetle, known as the "people's car," was conceived in the early 1930s under the directive of Adolf Hitler, who sought an inexpensive, simple vehicle for Germany's new highway system, the Reichsautobahn. Designed by Ferdinand Porsche, the Beetle's first production started in 1938, and by 2003, over 21. 5 million units had been manufactured, establishing it as one of the longest-lived and most popular cars globally. In the 1960s, various designations were introduced, including 1200 and 1600, and in 1998, Volkswagen released the New Beetle, a contemporary homage to the original design.
The Beetle gained significant traction in the U. S. during the 1960s, leading Volkswagen to build its first American factory, and by 1972, over 15 million Beetles had been produced, with a record-breaking 15, 007, 034th unit manufactured that February. Although production ceased in Germany in the late 1970s, the Beetle’s legacy endured, bringing it back to the market with the New Beetle model. The initial post-war period saw the first civilian Beetles crafted, culminating in mass production growth; by 1949, the first Type 1s had reached U.
S. shores. The Beetle's production spanned from 1945 until the last model rolled off the assembly line in Puebla, Mexico, on July 10, 2019. The car symbolizes durability and design nostalgia, remaining popular for decades despite its origins during a tumultuous historical period.
Do Egyptian Scarabs Still Exist?
Yes, Egyptian scarabs and scarab amulets still exist today as both artifacts and cultural symbols. Scarabs, deriving from the dung beetle, held significant meaning in ancient Egypt, representing the cycle of life, including concepts of birth, death, and resurrection. The beetle’s behavior of rolling dung balls, in which it laid its eggs, epitomized renewal and the eternal nature of existence. Scarabs were commonly used as amulets and impression seals, often inscribed with hieroglyphs that conveyed profound spiritual meanings.
These artifacts have survived for thousands of years and are abundant today, proving to be invaluable to historians and archaeologists seeking insight into ancient Egyptian culture. While they were revered as symbols of resurrection and the divine, modern Egypt sees the scarab more as a cultural emblem rather than a religious symbol. Despite this shift, scarabs continue to captivate both locals and tourists.
Currently, there are approximately 30, 000 species of scarabs, confirming the beetle's existence. Scarabs first emerged as artifacts during the late Old Kingdom period, primarily used for decorative and protective purposes. Beyond Egypt, scarabs have been found in various locations in the Near East, signifying their influence beyond national borders. Although modern portrayals of scarabs in popular culture, such as the film "The Mummy," exaggerate their characteristics, they remain an enduring symbol of ancient Egyptian heritage and spirituality.
Do They Use Beetles To Clean Bones?
Dermestid beetles, known as skin, carpet, or flesh-eating beetles, are specialized decomposers from the family Dermestidae that efficiently clean bones by consuming dead flesh, fur, and feathers, leaving only clean bones behind. They play a crucial role in nature as forensic scientists, aiding in the identification and display of bones in museums and by law enforcement. The beetles can consume all soft tissue in a matter of days to weeks, even on delicate bones, making them an ideal choice for safe bone cleaning.
Other methods can damage the bones or create fractures, which dermestids avoid. Taxidermists, museum curators, and academic institutions often rely on these beetles to clean skeletons effectively. To maintain a dermestid colony, a minimum of 300 beetles is required for a single skull, while 1, 000 to 5, 000 beetles may be necessary for larger specimens. After the beetles have consumed the soft tissues, cleaning with ammonia is recommended to remove fat and eggs before drying the bones at 40 °C.
Despite their effectiveness, dermestid beetles require careful management, making them challenging to maintain. In conclusion, while dermestid beetles serve as an efficient and safe cleaning method for bones, proper care and monitoring are essential for successful use.
How Do You Clean A Beetle Colony?
Cleaning specimens preserved in formalin and alcohol involves specific steps, such as soaking in water, hand-removing excess tissue, and coating remaining tissue with substances like bacon grease or cod liver oil. Utilizing a dermestid beetle colony significantly improves skull preparation and bone cleaning processes. Establishing the right habitat for these beetles is crucial for their health and efficiency. Once they have cleaned the flesh from a specimen, it's important to carefully remove the specimen and check for any remaining beetles or larvae.
Setting up an efficient dermestidarium can be achieved using various substrates, like quick oats, corn meal, or wheat bran. Proper care involves knowing how to feed and breed the beetles while avoiding issues like rotten meat and mites. These beetles are notably skilled at removing tissue without harming delicate bones.
Maintaining the colony's hydration can be done using wet paper towels or by spraying specimens, allowing beetles to drink. While managing the colony, cleaning can be challenging, but ensuring consistent moisture and providing dry meat or fish helps. Utilizing containers such as glass aquariums or plastic bins is suggested for the colony setup. With proper management, a colony can efficiently clean specimens, completing tasks like deer skull cleaning in just a couple of days.
How Long Do Dermestid Beetles Take To Clean A Skull?
The initial step in cleaning a deer skull involves giving dermestid beetles ample time to remove all flesh, which can take days to weeks, depending on the colony size. A prevalent inquiry is about how many beetles are necessary. Beetle larvae, only 12 millimeters long, can efficiently consume flesh. For large specimens like deer or elk skulls, a strong established colony of over 1, 000 beetles is recommended to achieve cleaning in approximately five days. Smaller colonies can manage but will take longer. Museum mites are a threat to these beetles, which thrive solely on fresh meat.
To prepare a deer skull for beetles, one typically starts by removing the cape, either via professional cleaning services or a DIY approach with a sharp knife. For optimal cleaning, a minimum of 300 beetles is needed, with 1, 000 to 5, 000 recommended for deer or bear skulls. The cleaning duration varies based on colony size and available material, ranging up to a few weeks, though properly prepared skulls will be cleaned quicker if major fleshy parts are already removed. If minimal meat remains on the skull, it may necessitate the addition of fat sources like bacon grease for better efficacy.
Once cleaning is complete, excess beetles should be removed by shaking them off, followed by soaking the skull in hot water for about 30 minutes. Efficient colonies can clear skulls in about 3-5 days, influenced by environmental factors like temperature and humidity. Thorough preparation and colony management are crucial for effective skull cleaning with dermestid beetles.
What Do Dermestid Beetles Eat?
Dermestid beetles, commonly known as skin beetles, are scavengers that thrive on materials of animal origin, including dead insects, pet hair, lint, and various fabrics like wool and furs. They are often referred to as "carpet beetles" due to their ability to feed on woolen carpets. Their larvae primarily consume dry organic matter, either animal or plant-based, and show a preference for a wide range of organic materials including paper, books, wool, cotton, taxidermy mounts, and feathers. Some larvae specifically consume grain or seed-based substances, while adults primarily feed on pollen from various flowers.
These beetles have evolved to require a protein-rich diet, primarily derived from decaying flesh, which is essential for their growth and reproduction. They essentially feed on any dried, dead, or decaying organic matter and possess a unique ability to digest materials such as wool and silk, making them a potential nuisance in households, where they can damage clothing and natural fibers.
Though they are classified as decomposers, helping to clean bones by consuming various organic detritus, they can also target stored foods, including grains, nuts, and dried goods like pasta. Dermestid larvae are particularly notorious for targeting raw animal skins, dried proteins, and items such as dried fish, stored pet food, and even museum specimens.
Their efficient scavenging and reproduction patterns often lead to higher densities in confined spaces, provided enough food is available. This adaptability makes them a common pest in homes and buildings. The variety of feeding habits among different dermestid species ensures that they play a crucial role in breaking down and recycling nutrients within ecosystems, while their larvae can even assist in cleaning delicate skeletons by consuming the smallest bits of tissue. Overall, dermestid beetles display a diverse and opportunistic feeding behavior, allowing them to thrive in various environments.
What Did The Egyptians Use Scarab Beetles For?
The scarab beetle, known as Scarabaeus sacer, was a profound symbol in ancient Egypt, embodying concepts of life, death, rebirth, and divine protection. Commonly found throughout Egypt, the scarab became a crucial motif in amulets, seals, and jewelry, believed to bring good fortune. The female scarab’s unique behavior—rolling a dung ball containing her eggs—intrigued Egyptians who closely observed this process.
In ancient Egyptian religion, the scarab was linked to the god Khepri, often associated with the rising sun and creation. The beetle not only symbolized rebirth and transformation but also served as a safeguard against evil, reflecting its role as a protective talisman. Scarab amulets were often placed in mummies, symbolizing a connection to the afterlife and the heart of the deceased during the New Kingdom period.
The scarab's significance extended beyond mere decoration: it was a sacred embodiment of solar and regenerative forces, paralleling other deities like Atum, who was believed to create life without a mate. Art frequently depicted scarab beetles, reinforcing their association with divine protection and the cyclical nature of existence.
In essence, the scarab beetle served as a powerful emblem of resurrection and spiritual endurance in ancient Egyptian mythology, encapsulating beliefs about the eternal cycle of life and the transformative power of divinity. Through its multifaceted representations, the scarab beetle continues to signify critical themes of renewal, protection, and the divine connection in ancient Egyptian culture.
How Did Beetles Remove Bones?
Before the advent of beetles for bone cleaning, two primary methods were employed: boiling or maceration, which involved odiferous bacterial action to separate flesh from bones. Small skulls, particularly from rodents, were encased in cheesecloth to retain tiny bones during the process. A technician meticulously removed the flesh and tendons by hand. Currently, after specimens are thawed in warm water, they are placed in Tupperware filled with Dermestid beetles, which efficiently consume the fur and tissue, leaving only the skeleton behind in just a few days.
Professor Tobias Landberg initiated this beetle colony to facilitate bone preparation by cutting open stomach cavities to extract organs and gather tissue samples. The primary task remains to thoroughly cleanse the bones without causing damage; hence, they depend on beetles, also known as skin or carpet beetles. These fast and effective decomposers play a vital role in recycling nutrients by removing soft tissue from bones.
Following initial manual cleaning by humans, carcasses are placed in a cage for beetles to complete the cleaning process. Dermestid beetles are essential for preserving the integrity of bones while efficiently stripping away organic matter.

Ok. whoever is making these articles … seriously…. I love everything. the perfect voice for voice over, perfect music to portray the sentiment of the reader but keeping it focused on the message at hand and the timing and movement on details like tags following the adult and larvae. great job!! 🙌🙌🙌
My science teacher in high school got a colony she kept in a big fish tank when we started taxidermy electives and it was a life saver! No other bug can give you quite the clean sweep without trying to carry the bones away too, but they can also be fed cat food between subjects! I love these little guys. Hope to have my own colony some day.
I got to see similar in real life. Lived on a property that had horses and one died. I’d visit it everyday to see what happened. After about a week the bloating went down and couple more days the stomach was moving from all the bugs inside. It was pretty gross. To me it was better than reading it from a text book.
Sometimes I wonder if when we die, we are meant to be eaten by bugs as part of the circle of life. I mean, think of what Mufasa said to Simba in the Lion King: “When we die, our bodies become the grass, and the antelope eat the grass. And so we are all connected in the great Circle of Life.” We die, the bugs eat us, the poop us out, then we become the earth (dirt), and then grow into grass, then animals can eat the grass or whatever, and the cycle goes on. So, I always pondered over whether a coffin is a good idea or not and if that’s what I’d want.
When I was 8 my dad caught a small yellow bird not native to where we live that he found flapping around the street. Turns out it was ill because not only could it not fly but it died about 2 weeks after we got him. Anyway I volunteered to burry him so I knew where he would be. I checked on him 3 times every 2 days to check his decomposition. The smell was horrid but the sight was intruiging. There were maggots and some other white bug that looked like the beatles here except completely white. Also there were holes in his skull just after 3 days not sure if he had that while alive though. Maybe that was his cause of death.
“In the end, bugs always win.” More truth to that than most might think. Ants alone compete with us for the highest biomass on the planet. I can’t imagine where we place in comparison to the entire insect population. We’re really just in their backyard, not the other way around. They are winning the reproduction game, and that game is really the only criteria for success as an organism.
we dug out a rabbit we buried about half a year ago in our sandbox (it was killed by a car). the summer was relatively wet, so we thought we give it a try. the rabbits fur was almost not touched at all and even some sinew was still attatched to some bones, especially the legs. some bones were covered in a black slimey substance. we will most likely not be able to put it completely together, because the feet are just too difficult. if we do this again, we will give the animal more time to decompose.
Well that’s why there’s cremation to consider. That way you won’t be eaten by bugs after you die (kinda pointless because you wouldn’t exist by then to feel that anyway), and less space is needed for burial. Also, you can choose creative ways to give back to nature, like scattering to the wind or ocean or a location of your choice.
