Cataulacus jeanneli

Quick Summary

• Difficulty: Medium
• Origin & Habitat: East Africa, found in coastal Kenya (Gazi, south of Mombasa), Rwanda (Akagera National Park), and the Democratic Republic of Congo. They live in arboreal habitats, nesting in hollow twigs and branches ^[1][2][3].
• Colony Type: Colony structure is unconfirmed. Based on genus patterns, likely single-queen (monogyne) colonies.
• Size & Growth:
  • Queen: Size data unavailable, not directly measured in available research
  • Worker: 2.5mm ^[1]
  • Colony: Unknown, no colony size data available
  • Growth: Unknown, no development data available
  • Development: Unknown, no species-specific data available (Development timeline has not been studied for this species.)
• Antkeeping:
  • Temperature: Keep around 24-28°C. Being from tropical East Africa, they prefer warm conditions. A heating cable on one side of the nest creates a suitable gradient.
  • Humidity: Moderate to high. As arboreal ants nesting in wood, they need some moisture but not saturation. Keep the nest substrate slightly moist but allow some drying areas.
  • Diapause: Likely no true diapause. Being from tropical Africa, they probably remain active year-round with slightly reduced activity in cooler months.
  • Nesting: Arboreal specialists, they need cavities to nest in. Hollow twigs, wooden formicariums, or acrylic nests with narrow chambers work well. Avoid large open spaces, they prefer tight, enclosed spaces.
• Behavior: Generally peaceful and not aggressive. Workers are small at 2.5mm and unlikely to sting. They are arboreal and will explore their surroundings but are not known escape artists compared to some tiny ants. They likely feed on honeydew from aphids and scale insects, plus small insects.
• Common Issues: very small size means escape prevention matters, use fine mesh and tight-fitting lids, lack of species-specific care data means you may need to experiment with conditions, arboreal nesting requirements differ from typical ground-nest setups, no documented development timeline makes growth tracking uncertain, wild-caught colonies may have parasites that affect captivity

Housing and Nest Setup

Cataulacus jeanneli requires arboreal-style housing. These ants naturally nest in hollow twigs and branches, so provide them with narrow cavities. Wooden formicariums or acrylic nests with small chambers work well. Avoid large, open spaces, they prefer tight, enclosed areas that mimic their natural twig nests. Test tubes can work for founding colonies if the cotton is positioned to create a small chamber. For established colonies, consider a naturalistic setup with actual twigs or small branches connected to a foraging area. Ensure excellent escape prevention despite their small size, 2.5mm workers can still squeeze through tiny gaps. ^[1]

Feeding and Diet

Based on typical Cataulacus behavior, these ants are likely omnivorous with a preference for honeydew and small prey. Offer sugar water or honey water as a constant energy source. For protein, provide small live prey like fruit flies, pinhead crickets, or tiny insects. They may also accept protein jelly or other prepared ant foods. Feed protein 2-3 times per week, and keep sugar sources available at all times. Remove uneaten prey after 24-48 hours to prevent mold.

Temperature and Humidity

Being from tropical East Africa, Cataulacus jeanneli prefers warm temperatures around 24-28°C. Use a heating cable on one side of the nest to create a temperature gradient so workers can choose their comfort zone. For humidity, aim for moderate levels. Keep the nest substrate slightly moist but allow portions to dry out. Avoid both excessive dryness and waterlogging. Good ventilation helps prevent mold while maintaining appropriate humidity. ^[2]

Colony Development and Growth

No species-specific development data exists for Cataulacus jeanneli. The queen has not been measured. Monitor colony health through worker activity levels and brood development. If workers cluster near heat, slightly increase temperature, if they avoid heated areas, reduce it.

Behavior and Temperament

Cataulacus jeanneli workers are tiny at 2.5mm and generally peaceful. They're not known for aggressive behavior or stinging. As arboreal ants, they're comfortable climbing and exploring vertical surfaces. Workers will likely forage for honeydew and small prey. While small, they're not extreme escape artists. Still, use proper escape prevention with tight-fitting lids. Their arboreal nature means they do well with climbing structures in their formicarium. ^[1]
