Species and Subspecies

Dung beetles are a diverse group of insects with over 7,000 known species distributed around the world. This vast number of species is divided into three primary groups based on their dung-handling behaviors: rollers, tunnelers, and dwellers. Each group represents various genera and species, adapted to different ecological niches.

  • Rollers (Telecoprids): These beetles are famous for rolling dung into balls, which are then used as food or breeding chambers. The African Scarab, Scarabaeus sacer, is a notable example.
  • Tunnelers (Paracoprids): These species bury dung directly beneath the dung pile. Species like Onthophagus gazella are common representatives of this group.
  • Dwellers (Endocoprids): Dwellers live directly in dung. They are often smaller and include species like Aphodius fimetarius.

The distinction between these groups lies not only in their behavior but also in their physical adaptations. Rollers, for example, tend to have stronger legs and more robust bodies to handle the physical demands of rolling dung balls. These differences are a perfect illustration of how dung beetles are adapted to their specific environmental roles.

Dung Beetle


Dung beetles are characterized by their robust and compact bodies. They vary in size, ranging from as small as 0.2 inches (5 mm) to as large as 1.4 inches (35 mm).

Their coloration can vary significantly, from dull and non-descript to strikingly metallic and vibrant. These beetles are known for their exceptionally strong front legs, adapted for digging and shaping dung.

Anatomically, dung beetles possess a highly specialized structure. Their antennae are distinctive, ending in a club with segments that can be tightly compressed or fanned out like leaves. This feature is crucial for sensing their environment and locating dung.

In terms of sexual dimorphism, males often have prominent horns used for fighting over mates and dung resources, while females generally lack these horns. The size and shape of the horns are species-specific and can range from small and simple to large and elaborate.

Habitat and Distribution

Dung beetles are found in a wide range of habitats, including deserts, forests, and farmlands, essentially anywhere where animal dung is present.

Their distribution is global, spanning every continent except Antarctica. Tropical regions, particularly in Africa and South America, boast the greatest diversity of dung beetle species.

These beetles are highly adaptable, with some species thriving in arid environments while others prefer moist rainforests. They are integral to their ecosystems, contributing to nutrient recycling, soil aeration, and seed dispersal.

Dung Beetle


Dung beetles exhibit a variety of behaviors that are fascinating both ecologically and evolutionarily:

Many species are diurnal, active during the day, while others are nocturnal. This variation often depends on the climate and the availability of dung.

Most dung beetles are solitary, but some species work in pairs or small groups, especially when rolling and burying dung balls.

Dung beetles rely heavily on their sense of smell to locate dung. They also use visual cues, such as the polarization patterns of moonlight, for navigation.

Dung beetles are known for their remarkable navigation skills. They can roll a dung ball in a straight line, navigating by the sun, moon, and even the Milky Way. This behavior is unique in the insect world and has been the subject of extensive scientific study.

Additionally, dung beetles display complex mating behaviors. Males often use their horns in combat to fend off competitors and gain access to females. After mating, both parents are often involved in shaping and burying the dung ball in which the female lays her eggs. This nurturing behavior ensures that their offspring have a food source immediately upon hatching.

Diet and Feeding Behavior

Dung beetles have a unique diet, primarily feeding on the feces of herbivores and omnivores. This diet choice plays a critical ecological role, as it helps decompose and recycle nutrients back into the soil. Their feeding behavior varies among species:

  • Rollers: These beetles shape dung into balls and roll them away from the main pile to avoid competition. The dung ball serves both as food and as a breeding chamber.
  • Tunnelers: These species dig a burrow beneath a dung pile and drag pieces of dung into this burrow. They consume the dung and also use it for breeding purposes.
  • Dwellers: Dwellers live and feed within the dung pile itself, consuming it as they go. They also breed within the dung.


Dung beetles face various predators throughout their life cycle. Birds, especially, are common predators of adult dung beetles. Other insects, such as wasps and ants, may prey on them too. In the larval stage, they are vulnerable to predation by small mammals, reptiles, and other insect larvae.

The beetle’s hard exoskeleton provides some defense against predation, and their habit of burying themselves in dung or soil offers additional protection. However, in open areas while rolling dung, they are more exposed and at risk from predators.

Reproduction and Life Cycle

Dung beetles have fascinating reproductive behaviors. The lifecycle of a dung beetle starts from an egg, progressing through larval and pupal stages, before emerging as an adult. This entire process can take several months to a year, depending on the species and environmental conditions.

In many species, males attract females by creating a dung ball, which serves as a nuptial gift and a breeding site. Some species display elaborate mating rituals, including battles between males using their horns.

The exact gestation period varies among species but generally lasts a few weeks. A female usually lays a single egg inside a dung ball or burrow. The larva feeds on the dung after hatching, providing a rich source of nutrients. In some species, parents may continue to guard the brood ball, ensuring the safety and development of the offspring.

These reproductive strategies, especially the creation and care of the dung balls, are key to the survival and success of dung beetle species, showcasing another aspect of their ecological importance.

Conservation and Threats

The conservation status of dung beetles varies widely among species. While many species are not considered endangered, they are susceptible to habitat loss and fragmentation, especially in regions undergoing rapid urbanization or deforestation.

Most dung beetle species are not on the endangered list. However, specific species in certain habitats are at risk due to environmental changes.

The primary threats include habitat loss, pesticide use, and changes in land use, which reduce the availability of dung and suitable breeding grounds.

Conservation efforts for dung beetles often involve habitat protection and restoration. Additionally, educating farmers about the ecological benefits of dung beetles can help in reducing pesticide use and promoting practices that support dung beetle populations.

Fun Facts

  1. Impressive Strength: Dung beetles are the strongest insects in the world. Some species can pull objects over 1,000 times their body weight – the equivalent of a human pulling six double-decker buses!
  2. Astronomical Navigators: Dung beetles are known to use the Milky Way as a navigational aid – the only known non-human species to do so.
  3. Ancient Symbolism: In ancient Egypt, the dung beetle, or scarab, was revered as a symbol of transformation and rebirth, relating to how they roll dung into balls, similar to how the sun god Ra rolls the sun across the sky.
  4. Eco-Friendly: By burying and consuming dung, they help reduce greenhouse gas emissions from dung piles, particularly methane, a potent greenhouse gas.
  5. Variety of Species: With over 7,000 species, dung beetles display a vast array of behaviors and adaptations, making them one of the most diverse groups of insects on the planet.
