Crematogaster bequaerti

Quick Summary

• Difficulty: Unknown, likely Medium based on typical Crematogaster care
• Origin & Habitat: Tropical Central Africa, Democratic Republic of Congo, Guinea, Nigeria, and Rwanda. Found in forest environments, likely in rotting wood or under bark ^[1][2][3].
• Colony Type: Colony structure is unconfirmed for this specific species
• Size & Growth:
  • Queen: Size data unavailable, inferred from Crematogaster genus patterns (~5-7mm)
  • Worker: Size data unavailable, inferred from Crematogaster genus patterns (~2-4mm)
  • Colony: Likely several hundred workers, estimated from genus patterns
  • Growth: Unknown, likely moderate based on genus patterns
  • Development: Estimated 6-8 weeks at tropical temperatures based on related Crematogaster species (Timeline is inferred from genus-level data, not directly studied for this species)
• Antkeeping:
  • Temperature: Keep at 24-28°C, this matches their tropical African origin and typical Crematogaster preferences. A slight gradient allowing cooler areas around 22°C is beneficial.
  • Humidity: Maintain 60-80% humidity. These are forest-dwelling ants that prefer consistently moist conditions without being waterlogged. Provide a water tube for drinking access.
  • Diapause: Unlikely, as a tropical species from Central Africa, they probably do not require a hibernation period. Keep temperatures stable year-round.
  • Nesting: Y-tong (AAC) nests or plaster nests work well for this size ant. Provide nesting chambers with moderate humidity. They may also accept test tube setups if given proper humidity control. Avoid dry, airy nests.
• Behavior: Crematogaster ants are generally active and alert workers. They are known for raising their abdomen over their head when threatened, this is a defensive display and they may smear venom onto enemies using their modified stinger. They are not typically aggressive toward humans but will defend their nest. Workers are small but fast-moving. Escape prevention should be moderate, their small size means they can slip through larger gaps.
• Common Issues: limited documented care information means some trial and error may be needed, tropical humidity requirements can lead to mold if ventilation is poor, small colony sizes may make them appear slow-growing compared to faster species, wild-caught colonies may have parasites or diseases not yet documented for this species

Housing and Nest Setup

Crematogaster bequaerti is a small ant that does well in Y-tong (AAC) nests or plaster formicariums. The nesting chambers should be appropriately sized, not too large, as these ants prefer cozy spaces. A test tube setup can work for founding colonies, but monitor humidity carefully as test tubes can develop mold issues if over-watered. For outworld space, provide a modest foraging area. They are not large climbers, so vertical space is less critical than for arboreal species. Use a water tube or small water dish for drinking access, Crematogaster species readily use water sources.

Feeding and Diet

Like other Crematogaster species, these ants are generalist feeders. Offer sugar water, honey, or diluted syrup as a constant carbohydrate source. For protein, provide small insects like fruit flies, pinhead crickets, or mealworm pieces. They are not large predators, so prey items should be appropriately sized. Some Crematogaster species also collect honeydew from aphids if available. Feed protein sources 2-3 times per week, and keep sugar water available at all times. Remove uneaten prey after 24-48 hours to prevent mold.

Temperature and Humidity

Maintain temperatures between 24-28°C, reflecting their tropical African origin. A slight temperature gradient is beneficial, allow one area of the nest to be around 22°C while another reaches 28°C so the ants can self-regulate. Humidity should be kept at 60-80%. These forest-dwelling ants prefer consistent moisture but not saturated conditions. Monitor for condensation, some moisture is good but excessive water can harm the colony. Unlike temperate species, they do not require a winter cooling period.

Behavior and Colony Dynamics

Crematogaster workers are known for their characteristic defensive behavior, when threatened, they raise their abdomen over their head, which is how they earned the common name 'acrobat ants'. They may also use their modified stinger to smear venom onto enemies rather than piercing. Workers are active foragers and will quickly discover and exploit food sources. The colony will likely grow from a single queen to several hundred workers over time. Founding behavior is unconfirmed for this species.

Handling and Temperament

This species is not considered dangerous to humans. While they have a stinger, Crematogaster species rarely use it on keepers due to their small size. They are more likely to use their defensive chemical secretion or simply flee. They are not aggressive toward humans but will defend their nest if threatened. For observation, they are interesting ants to watch due to their active foraging and characteristic abdomen-raising behavior.
