Cataulacus bequaerti

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Democratic Republic of Congo (provinces EQ, HK, HL) in tropical Central Africa. In the wild, these ants nest in empty galls on trees, typically found in forest canopy environments ^[1][2].
• Colony Type: Unconfirmed, specific colony structure data is not available for this species.
• Size & Growth:
  • Queen: Size data unavailable, no specific measurements exist in research literature. Estimated 6-8mm based on genus patterns for Cataulacus.
  • Worker: Size data unavailable, no specific measurements exist in research literature. Estimated 4-6mm based on genus patterns for Cataulacus.
  • Colony: Unconfirmed, no specific colony size data available.
  • Growth: Unknown, no development studies exist for this species.
  • Development: Unknown, no specific development data available for this species. (Development timeline has not been studied. Estimates based on related species may not be accurate.)
• Antkeeping:
  • Temperature: Keep warm, roughly 24-27°C. Tropical species require consistent warmth. A heating cable on one side of the nest creates a suitable gradient.
  • Humidity: High humidity preferred. These forest canopy ants need moist conditions. Mist regularly and provide a water tube.
  • Diapause: No, being a tropical species, they do not require hibernation. Maintain warm conditions year-round.
  • Nesting: Arboreal cavity-nesters. They naturally nest in hollow plant structures like galls and stems. In captivity, they do well in test tube setups placed horizontally, small nests with narrow chambers, or cork bark setups. Avoid standard soil formicariums, they prefer enclosed spaces.
• Behavior: Generally calm and non-aggressive. As arboreal ants, they are skilled climbers and will explore vertical spaces. They are not known for stinging and pose no danger to keepers. Escape prevention is important, while not tiny, they can squeeze through small gaps. They are active foragers that will search for honeydew and small prey.
• Common Issues: high humidity requirements can lead to mold if ventilation is poor, arboreal nature means they may struggle in ground-level nests designed for soil-dwelling species, limited research means exact dietary preferences are uncertain, tropical species are sensitive to temperature drops, keep away from cold drafts, small colony size means slower population growth, patience is required

Housing and Nest Setup

Cataulacus bequaerti requires housing that mimics their natural arboreal cavity-nesting habitat. In the wild, they inhabit empty galls on trees, hollow plant structures that provide enclosed, humid conditions ^[1]. For captivity, test tubes work well when laid horizontally, allowing the queen to seal herself in a dark chamber. You can also use small nests with narrow chambers or cork bark setups. Avoid large, open spaces, these ants feel secure in tight, enclosed areas. Place the nest in a vertical orientation if possible, reflecting their tree-dwelling lifestyle. A small outworld for foraging completes the setup.

Feeding and Diet

Like most Cataulacus species, these ants are likely omnivorous with a preference for sugary substances and protein. In nature, arboreal ants often tend aphids for honeydew and hunt small insects. In captivity, offer sugar water or honey water regularly as a constant food source. For protein, provide small insects like fruit flies, pinhead crickets, or mealworm pieces. Feed protein several times per week, and keep sugar water available at all times. Remove uneaten prey after a day or two to prevent mold.

Temperature and Humidity

Being a tropical species from the DRC, Cataulacus bequaerti requires warm and humid conditions. Maintain temperatures in the range of 24-27°C, use a heating cable on part of the nest if your room temperature is below this range. Place the heating on top of the nest, not underneath, to avoid excessive evaporation. Humidity should stay relatively high. The enclosed nature of their nests helps maintain humidity, but you should still mist the outworld regularly and provide a water tube. Good ventilation is important to prevent mold while maintaining humidity.

Colony Development

Colony growth rate is unknown for this species. The queen will seal herself in a chamber during founding and raise the first workers on her stored energy reserves. Once the first workers emerge, the colony will begin expanding. The exact timeline for first workers emerging has not been studied. Growth will likely be slower than many ground-nesting ants, so patience is essential.
