Proceratium creek

Quick Summary

• Difficulty: Expert
• Origin & Habitat: Southeastern United States, known only from Thomas County, Georgia, Lafayette County, Florida, and Arkansas. This ant lives entirely underground in the burrow systems of pocket gophers (Geomys pinetis), making it a highly specialized subterranean species ^[1].
• Colony Type: Colony structure is unconfirmed. Only a handful of specimens have ever been collected, and no observations of natural colony structure exist.
• Size & Growth:
  • Queen: 5.50-5.70 mm ^[1]
  • Worker: Over 5.5 mm (largest in Pergandei Clade) ^[2][3]
  • Colony: Unknown, only a few specimens have ever been collected
  • Growth: Unknown
  • Development: Unknown, no captive breeding observations exist (This species has never been kept in captivity, so no development timeline is available)
• Antkeeping:
  • Temperature: No data, as a subterranean species from the southeastern US, likely cool and stable (around 18-22 °C), but this is completely speculative. Avoid overheating, keep at room temperature or slightly below and observe.
  • Humidity: Unknown but likely very high. Their natural gopher burrow habitat is damp and dark. Keep the nest substrate consistently moist (not waterlogged) and avoid any dry areas.
  • Diapause: Unknown, as a temperate species, winter rest may be needed, but no observations exist.
  • Nesting: This is a subterranean species that naturally lives in gopher burrows. Provide a fully enclosed, dark, humid nest, test tubes or Y‑tong/plaster setups work best. Expect the colony to stay inside most of the time and not use an outworld frequently. Keep chambers damp and dark ^[1].
• Behavior: 5 mm) and probably not strong climbers. Their behavior in captivity is completely unknown, this species has never been kept by antkeepers.
• Common Issues: this species has never been kept in captivity, there are no established care protocols, extreme rarity means finding a colony to start with is nearly impossible, subterranean lifestyle makes them difficult to observe and care for properly, no information on what they eat in captivity, Proceratium species are typically predators, hypothetical care requirements may not match actual species needs

Why This Species Is So Challenging

Proceratium creek is arguably the most difficult North American ant to keep because virtually nothing is known about its captive care. This species has been collected only a handful of times, always from underground gopher burrows, and has never been observed in captivity ^[1]. Every care recommendation for this species is speculative at best. The ants are extremely rare in the wild, most antkeepers will never encounter them. If you do obtain specimens, expect a steep learning curve with no community experience to draw from. This is truly a species for advanced antkeepers with the resources to experiment and document their findings.

Natural History and Habitat

This species is known only from the southeastern United States, specifically Georgia, Florida, and Arkansas. Every single specimen has been collected from pitfall traps placed inside burrow systems of pocket gophers (Geomys pinetis). The trapping process itself is remarkable, researchers had to first trap and remove the gopher, or it would fill in the pitfall traps. The traps were then placed in the burrow system and carefully covered with a board and soil to prevent them from filling with soil ^[1]. This tells us Proceratium creek is a fully subterranean species that likely spends its entire life underground, rarely if ever coming to the surface. The gopher burrow environment is dark, humid, and temperature‑stable year‑round.

Identification and Appearance

Workers of Proceratium creek are the largest in the Pergandei Clade of Proceratium species. They can be identified by their low, rounded petiole (the narrow waist segment) similar to the related Proceratium pergandei, but with notably longer antennal scapes that actually exceed the posterior margin of the head when laid back against the head. If you find what appears to be a giant Proceratium pergandei, it might actually be this rare species. Queens measure 5.50-5.70 mm, while males are around 5.65 mm. The body is ferruginous‑brown in color ^[1].

Housing and Nest Setup

Given their completely subterranean lifestyle, housing Proceratium creek requires a different approach than most ants. They should be kept in complete darkness most of the time, with only occasional observation light. A test tube setup or fully enclosed Y‑tong/plaster nest works best. The nest chambers should be kept humid at all times, think damp soil, not wet standing water. Since they live in gopher burrows, they likely prefer deeper enclosures rather than shallow ones. Do not expect them to use an outworld frequently or at all. They will probably remain in the dark, humid nest chambers and forage in any connected foraging area only at night or in complete darkness ^[1].

Feeding and Diet

The diet of Proceratium creek in captivity is completely unknown. Other Proceratium species are typically predators, often specializing in hunting spider eggs and other small arthropods. In captivity, you could experiment by offering small live prey like springtails, fruit flies, or other tiny arthropods. Sugar sources are unlikely to be accepted, these are predatory ants, not sugar‑seekers. Given how little we know about this species, document any feeding observations carefully. This is another area where antkeepers would need to pioneer captive protocols.

Legal and Ethical Considerations

Proceratium creek is an extremely rare species with a very limited known range. If you ever encounter this species in the wild, extreme caution should be exercised before collecting any specimens. This species may have conservation status in some areas, and collecting should only be done with proper permits and for the purpose of establishing captive colonies for educational or conservation purposes. Never release any ant colonies in the United States, even native species can cause ecological problems if introduced to new areas.
