Dorylus savagei

Quick Summary

• Difficulty: Expert
• Origin & Habitat: Tropical Central Africa (Democratic Republic of Congo, Gabon, Guinea, Nigeria). In the wild, these ants likely inhabit forest floors where they can conduct large-scale raids ^[1].
• Colony Type: Colony structure is completely unconfirmed. Only male specimens have been described in scientific literature. Dorylus genus members typically form large colonies, but colony structure for this specific species is unknown.
• Size & Growth:
  • Queen: Size data unavailable, only male specimens have been described in scientific literature ^[1].
  • Worker: Size data unavailable, worker caste has not been documented in scientific literature.
  • Colony: Unknown for this specific species. Dorylus genus colonies can reach hundreds of thousands of workers, but no data exists for D. savagei.
  • Growth: Unknown, no development data exists for this species.
  • Development: Unconfirmed, no development data exists for Dorylus savagei. (Development timeline is undocumented for this species.)
• Antkeeping:
  • Temperature: Keep at tropical temperatures. Specific requirements are unconfirmed for this species, start around 24-28°C and observe colony response.
  • Humidity: Maintain high humidity similar to rainforest floor conditions. Keep the nest substrate consistently moist but not waterlogged.
  • Diapause: No, Dorylus species are tropical and do not require hibernation.
  • Nesting: Large, spacious nests are essential. Y-tong (AAC) nests or large naturalistic setups work well. Provide deep substrate for tunneling. Ensure excellent escape prevention, army ants find any gap in enclosure seals.
• Behavior: Dorylus savagei is an army ant. Specific behavior is unconfirmed, but Dorylus genus members typically form raiding columns that sweep through territory, capturing other insects and arthropod prey. Workers are aggressive and will defend the colony. Escape prevention is critical, army ants can squeeze through small gaps. The sting is present but pain level for this specific species is unconfirmed.
• Common Issues: massive colony size makes housing challenging, plan for expansion from the start, escape prevention is critical, army ants will find and exploit any gap, feeding becomes extremely demanding at colony maturity, nomadic behavior means colonies may become restless and attempt to relocate, no specific care data exists for this species, keepers must rely on genus-level guidance, this species has not been documented in captivity before

Housing and Enclosure Setup

Dorylus savagei requires specialized housing due to their potential for large colony growth and escape abilities. Use a large outworld connected to a spacious nest area. Y-tong (AAC) nests work well because they provide darkness for brood chambers and allow for observation. Alternatively, a large naturalistic setup with deep soil substrate mimics natural forest floor nesting. Escape prevention is critical, apply Fluon or similar barrier to all enclosure edges. Ensure ventilation is adequate but not excessive. The enclosure should be sealed with no gaps larger than 0.5mm.

Feeding and Nutrition

Dorylus savagei is predatory, like all army ants. They raid other ant colonies and arthropod prey in the wild. In captivity, offer protein sources: live insects (crickets, mealworms, roaches), other ant colonies as prey, and various arthropods. Feed generously, a mature colony may consume thousands of prey items per week. Some colonies may accept protein jelly or canned insects, but live prey is preferred. Feed more heavily when the colony has brood to raise. Remove uneaten prey after 24-48 hours to prevent mold.

Temperature and Seasonal Care

As a tropical African species, Dorylus savagei requires warm conditions year-round. Maintain temperatures between 24-28°C. Temperatures below 22°C can slow colony development significantly, and prolonged cold can be fatal. Use a heating cable placed on top of the nest material to create a warmth gradient. Monitor with a thermometer near the brood chambers. There is no diapause requirement, these ants remain active throughout the year.

Behavior and Colony Dynamics

Dorylus savagei likely exhibits typical army ant behavior. Colonies conduct raids where columns of workers sweep across territory, overwhelming prey colonies. They are primarily nocturnal, with raid activity often increasing at night. Workers are aggressive and will sting defenders. Unlike some army ant genera, Dorylus queens are fully winged, allowing for dispersal during nuptial flights. The colony may exhibit nomadic behavior, occasionally relocating within the enclosure.

Legal and Ethical Considerations

Before acquiring Dorylus savagei, verify that it is legal to keep in your jurisdiction. Some countries have restrictions on native ant collection or foreign species import. Never release this species or any ant colony into the wild outside its native range, Dorylus savagei is native to Central Africa (DRC, Gabon, Guinea, Nigeria) and could become invasive in other tropical regions. If you can no longer keep the colony, contact a local ant keeper or entomological society to rehome it.
