Dorylus buyssoni

Quick Summary

• Difficulty: Expert
• Origin & Habitat: Kenya, East Africa (Afrotropical region). The type locality is Nairobi. Based on other Dorylus species, they likely inhabit forest edges and savanna habitats where they form massive colonies that conduct raiding swarms ^[2].
• Colony Type: Unknown, only males have been described. Dorylus species typically form large colonies with single queens (monogyne), but this species is too poorly documented to confirm ^[2].
• Size & Growth:
  • Queen: Size data unavailable, no queens have been described
  • Worker: Size data unavailable, no workers have been described
  • Colony: Unknown, no colony data exists
  • Growth: Unknown
  • Development: Unknown, no development data exists (No brood or developmental stages have ever been documented for this species)
• Antkeeping:
  • Temperature: Unknown for this species. Dorylus species are tropical and prefer warm conditions, but specific requirements for D. buyssoni are unstudied.
  • Humidity: Unknown. Dorylus species generally prefer humid conditions similar to their tropical forest habitats.
  • Diapause: Unknown. Most Dorylus species are tropical and do not hibernate, but this has not been studied for D. buyssoni.
  • Nesting: Unknown. Dorylus species typically create temporary bivouacs in soil or rotting wood and move frequently (nomadic lifestyle). No specific nesting observations exist for this species.
• Behavior: Unknown, this species has never been documented in captivity or studied for behavior. Dorylus genus members are known for their aggressive raiding behavior, large colony sizes, and nomadic nest movement. Workers are blind or nearly so. However, none of this has been confirmed for D. buyssoni specifically.
• Common Issues: this species has never been documented in captivity, no established care protocols exist., only males have been scientifically described, obtaining a colony would require finding one in the wild., the species is extremely rare with only a handful of specimens known from a single location., no worker or queen morphology means positive identification would be nearly impossible., dorylus colonies can be aggressive and deliver painful stings, exercise extreme caution if attempting to keep.

What We Know About This Species

Dorylus buyssoni was first described by Felix Santschi in 1910 based on four male specimens collected near Nairobi, Kenya in 1904. The type specimens were collected by Ch. Alluaud from the Wa-Kikouyou area (likely modern-day Kikuyu) ^[1]. That's it. That's essentially all the documented scientific information about this species. No workers, no queens, no colonies, no biological observations, no ecological data. The subspecies Dorylus buyssoni conjugens was also described but similarly lacks any additional documentation ^[2]. This is one of the least known ant species in the entire Dorylinae subfamily.

Why This Species Is Not Available in the Antkeeping Hobby

This species has never been documented in the antkeeping hobby and likely cannot be obtained. The primary reason is simple: only male specimens have ever been collected and described by scientists. Without workers or queens, there is no way to establish a captive colony. Even if a wild colony were discovered, Dorylus colonies are massive (often hundreds of thousands of individuals) and extremely aggressive, making collection and transport impractical. The species appears to be either very rare, very localized, or both. No specimens have been reported in modern entomological surveys, suggesting either the species is genuinely scarce or may have been misidentified in the original description. ^[2]

General Dorylus Biology (Genus-Level Information)

While D. buyssoni specifically is unknown, the Dorylus genus is among the most studied army ants in the world. These are the famous African driver ants that form colonies potentially exceeding 20 million individuals. They are nomadic, moving their bivouac (temporary nest) every few weeks as food sources are exhausted. Unlike many ants, Dorylus workers are largely blind, navigating instead through chemical trails and mass recruitment. They conduct massive raiding swarms that overwhelm prey including insects, spiders, and occasionally small vertebrates. Queens are enormous and continuously produce eggs. However, none of this has been confirmed for D. buyssoni specifically, and this species may have entirely different biology. ^[2]

Is It Possible to Keep This Species?

No. This species is not available in the antkeeping hobby and cannot be recommended for keeping. The complete lack of any documented colony, worker, or queen means there is no way to establish a captive population. Even if you somehow obtained a wild colony, positive species identification would be impossible without the described worker caste. Additionally, Dorylus colonies are among the most difficult ants to maintain in captivity due to their massive size, aggressive nature, nomadic behavior, and specific dietary needs. If you are interested in army ants, consider better-documented Dorylus species like Dorylus fulvus or Dorylus nigricans, or explore other genera entirely. This species remains a mystery to science and should remain so, attempting to collect it would be scientifically irresponsible and practically impossible.
