Monomorium dolatu

Quick Summary

• Difficulty: Medium
• Origin & Habitat: West Africa (Cameroon, Ghana, Ivory Coast) in Sclerocarya-Bolusanthus Open Woodland and forest-savanna mosaic habitats. This species is arboreal, living in trees and shrubs rather than on the ground ^[2][1].
• Colony Type: Colony structure is unconfirmed. No specific data on queen number or colony organization exists for this species.
• Size & Growth:
  • Queen: Size data unavailable, queen has not been described
  • Worker: ~1.5mm ^[1]
  • Colony: Unknown, no colony size data available
  • Growth: Unknown
  • Development: Unknown (No development data available for this species)
• Antkeeping:
  • Temperature: Keep warm at 24-28°C, these are West African ants that prefer tropical conditions.
  • Humidity: Moderate humidity around 60-70%. As an arboreal species, they prefer slightly drier conditions than ground-nesting ants.
  • Diapause: No, being a tropical West African species, they do not require hibernation. Keep warm year-round.
  • Nesting: Arboreal specialists, they naturally nest in hollow twigs, branches, and under bark. In captivity, they do well in small Y-tong nests or test tubes with appropriately scaled small chambers. Avoid large, open spaces.
• Behavior: These are very small ants that are not aggressive. They are arboreal foragers, actively searching vegetation for honeydew and small prey. Because of their tiny size, escape prevention is critical, they can squeeze through remarkably small gaps. Workers are relatively slow-moving. They belong to the Myrmicinae subfamily and have a sting, though their small size makes stinging humans unlikely.
• Common Issues: tiny size makes escape prevention challenging, use fine mesh and tight-fitting lids, limited species-specific information means care is based on genus knowledge, arboreal nature means they may not thrive in ground-based setups, no colony size data available, actual maximum unknown, queen size and development timeline unconfirmed

Housing and Nest Preferences

Monomorium dolatu is an arboreal species, meaning it naturally lives in trees and shrubs. In the wild, they nest in hollow twigs, under bark, and in decaying wood on standing trees. For captive care, small Y-tong formicaria work well because the chambers can be scaled to their tiny size. Test tubes with cotton plugs can work for founding colonies, but ensure the water reservoir is not too large to avoid flooding such small ants.

Avoid large, open spaces in the nest, these tiny ants feel secure in tight, enclosed chambers. The outworld should also be appropriately scaled. Because they are arboreal, they may benefit from vertical climbing structures in their foraging area. Use fine mesh on any ventilation holes, these ants can escape through gaps that would not concern larger species. ^[2][1]

Feeding and Diet

Like other Monomorium species, M. dolatu is likely a generalist omnivore. In nature, they probably forage for honeydew from aphids and scale insects, and hunt small soft-bodied prey. In captivity, offer sugar water or honey diluted with water as a constant energy source. For protein, provide small live prey such as fruit flies or small insects. Because of their tiny size, prey items should be appropriately scaled.

Feed small amounts every few days, removing any uneaten prey after 24 hours. Sugar water can be provided on a cotton ball or through a small test tube feeder, refreshed regularly. Monitor colony activity and adjust feeding as needed.

Temperature and Humidity

As a West African species from tropical regions, Monomorium dolatu requires warm conditions. Keep the nest area at 24-28°C for optimal brood development. A heating cable on one side of the nest can create a gentle gradient, allowing workers to regulate their temperature by moving between warmer and cooler areas. Room temperature may be sufficient if your home stays in the low-to-mid 20s°C range.

For humidity, aim for moderate levels around 60-70%. As arboreal ants, they prefer conditions that are less humid than ground-nesting species. Allow the nest substrate to dry partially between waterings, providing both moist and drier areas. Good ventilation helps maintain appropriate humidity while preventing stagnation.

Colony Development

No specific data exists for colony development in this species. The founding process is unconfirmed, while many Monomorium species are claustral, this has not been verified for M. dolatu. Expect slow but steady growth over the first several months. Do not overfeed during the founding stage, as excess food can mold and harm the queen. Patience is key with this species.

Behavior and Temperament

Monomorium dolatu workers are small and not particularly aggressive. They are arboreal foragers, actively searching vegetation rather than ground surfaces. Their tiny size makes them vulnerable to larger predators, so they avoid confrontation. They have a sting but are extremely unlikely to sting humans due to their minute size.

The most significant behavioral consideration is their small size. While not aggressive, they are excellent at finding tiny gaps in enclosures. Excellent escape prevention is essential, use fluon on test tube rims, fine mesh on ventilation, and ensure all connections are sealed. ^[1]
