Aardwolf
Proteles cristata
Beneath the quiet African night sky, the aardwolf (Proteles cristata) roams the grasslands in search of termites. Though it resembles a small striped hyena, its behavior and diet tell a different story. This gentle, nocturnal mammal survives not by scavenging, but by delicately lapping up thousands of termites every night—an extraordinary example of adaptation and balance in the wild.

1. Taxonomy and Classification
Scientific Name
Proteles cristata
Evolutionary Relationships
The aardwolf is the only surviving member of the subfamily Protelinae. It diverged from other hyenas about 15–30 million years ago and evolved to feed almost entirely on termites. Its name, meaning “earth wolf,” reflects both its ground-dwelling habits and its primitive five-toed front feet, a feature lost in other modern hyenas.

2. Physical Characteristics
Every aspect of the aardwolf’s body reflects its adaptation to a peaceful, insect-eating lifestyle rather than scavenging or predation.
Size and Body Shape
Length
22–31 inches (55–80 cm)
Height
16–20 inches (40–50 cm)
Weigh
18–26 pounds (8–12 kg)
Small and slender, the aardwolf stands about 40–50 centimeters (1.3–1.6 feet) tall at the shoulder and measures 55–80 centimeters (22–31 inches) in body length. The tail adds 20–30 centimeters (8–12 inches), and adults weigh between 8 and 12 kilograms (18–26 pounds). Long legs and a narrow frame give it a graceful, almost fox-like look suited for silent movement through the grass.
Coat and Body Features
The soft, sandy-yellow coat blends perfectly with dry savannas. A dark mane runs from the back of the neck to the tail and can stand upright when the animal feels threatened. Its large, pointed ears and narrow muzzle help it detect termite activity hidden beneath the soil.
Colors and Patterns
Bold black stripes along the body and legs help the aardwolf disappear among tall grasses, while the tail ends in a distinctive black tip. The stripes vary subtly from one individual to another.
Unique Features
Unlike other hyenas, the aardwolf has five toes on its front feet and small, peg-like teeth for crushing soft-bodied insects. Its long, sticky tongue is a specialized tool, capable of collecting thousands of termites in minutes without harming their mounds.
3. Behavior and Ecology
The aardwolf leads a quiet, secretive life that mirrors its gentle feeding habits and nocturnal rhythm.
Diet
The aardwolf’s diet consists almost entirely of harvester termites such as Trinervitermes and Hodotermes. Guided by scent, it follows termite trails and consumes vast numbers each night. It never destroys termite mounds, ensuring colonies remain active and sustainable.
Daily Activity Patterns
Mostly nocturnal, aardwolves emerge after sunset and feed through the night. During the day, they rest in burrows—often those once used by aardvarks or porcupines—to avoid the heat and stay safe from predators.
Social Structure
Aardwolves live either alone or in monogamous pairs that share and defend a territory marked with scent. While foraging is a solitary task, pairs cooperate in raising cubs and guarding the den.
Communication
Communication relies on scent marking, vocal calls, and mane-raising displays. The strong scent from their anal glands helps identify territory and signal to mates. When threatened, they raise their mane and emit low growls to deter intruders.
Reproduction and Parenting
After about 90 days of gestation, females give birth to two to five cubs in a burrow. Both parents guard and care for the young. As they grow, cubs accompany adults on nighttime foraging trips before eventually becoming independent.
4. Habitat and Distribution
The aardwolf thrives in Africa’s open landscapes, where its insect prey is most abundant. It avoids deserts and dense forests, preferring warm, grassy environments.
Geographic Range
Two main populations exist: one across southern Africa (South Africa, Namibia, Botswana, Zimbabwe) and another across eastern Africa (Tanzania, Kenya, Ethiopia). Though separated by unsuitable habitat, both populations live in similar grassland environments.
Preferred Habitat
Aardwolves inhabit open grasslands, shrublands, and lightly wooded savannas that support termite colonies. These areas offer both cover and food in abundance.
Climate Preferences
They favor semi-arid climates with moderate rainfall, avoiding regions that are extremely dry or persistently wet. Termite activity—and therefore aardwolf feeding—rises during humid conditions.
Elevation Range
Aardwolves typically occupy lowland and mid-elevation plains below 2,000 meters (6,500 feet).
Human Impact
Agricultural expansion, road traffic, and persecution can threaten local populations, though these impacts remain limited. Many aardwolves live safely in reserves, and awareness campaigns continue to reduce human conflict.
5. Role in the Ecosystem
The aardwolf’s quiet existence has a powerful ecological effect.
Ecological Importance
By consuming enormous numbers of termites, aardwolves help maintain the balance of grassland ecosystems. Their feeding prevents termite overgrazing, supports healthy vegetation, and benefits grazing animals. Because they leave termite mounds intact, their relationship with the insects remains sustainable.
Relationships with Other Species
Aardwolves share their habitat with aardvarks, bat-eared foxes, and insect-eating birds. Each targets different prey or feeding times, reducing competition. Large carnivores such as lions and leopards may occasionally prey on aardwolves or their young, though such encounters are rare.
6. Conservation, Threats, and Predators
The aardwolf remains one of Africa’s more secure carnivores, but continued habitat care is key to its stability.
Global Conservation Status
The aardwolf is listed as Least Concern on the IUCN Red List. It is widespread, stable, and protected across much of its range.
Population Trends
Populations are stable overall, though localized declines occur in heavily cultivated or urbanized areas.
Threats
The main threats include habitat loss, road collisions, and poisoning linked to predator-control efforts. Misidentification as a livestock threat still leads to some unnecessary killings.
Natural Predators
Young aardwolves may fall prey to lions, leopards, and hyenas. Adults rely on stealth, nocturnal behavior, and burrows for protection.
Conservation Efforts
Populations remain secure within major reserves such as Kruger and Serengeti National Parks. Education programs and habitat protection continue to strengthen coexistence with humans.
7. Human Interaction and Cultural Significance
Aardwolves live quietly near human settlements and cause no harm. By keeping termite populations balanced, they indirectly protect grazing land. In regions where they were once misunderstood, eco-education has helped promote respect for this gentle species.
In African folklore, the aardwolf symbolizes quiet persistence. Its name—“earth wolf”—captures both its elusive nature and its connection to the life-rich soil that sustains it.

- Its mane rises when threatened, making it appear nearly twice its size.
- It leaves termite mounds intact, allowing colonies to thrive again.
- The aardwolf’s tongue can pick up thousands of termites per minute.
- Its name means “earth wolf” in Afrikaans and Dutch.
- It communicates through scent marking with glands beneath its tail.
9. Tips for Observing
Spotting an aardwolf in the wild is rare but unforgettable. They are most visible at night when termite activity peaks.
Where to Spot Them
Look for them in open reserves such as Kruger (South Africa), Etosha (Namibia), or Serengeti (Tanzania). Guided night drives offer the best opportunities.
Best Times to Observe
Dusk and early nightfall are ideal, particularly in the dry season when termites are active above ground.
Signs of Presence
Small, licked openings on termite mounds and faint paw prints near burrows often indicate their presence.
Safety Note
Aardwolves are harmless and easily startled. Maintain a quiet distance, stay inside vehicles, and use red-filtered lights to watch without disturbing them.
