Chelaner croceiventre

Quick Summary

• Difficulty: Unknown, likely Easy to Medium based on genus patterns
• Origin & Habitat: New Caledonia, a tropical Pacific island ^[4]. Specific habitat preferences are unconfirmed.
• Colony Type: Unconfirmed, colony structure data does not exist for this species
• Size & Growth:
  • Queen: Size data unavailable, no measurements exist for this species
  • Worker: Size data unavailable, no measurements exist for this species
  • Colony: Unknown, no colony size data exists for this species
  • Growth: Unknown, no development data exists for this species
  • Development: Unconfirmed, no specific development data exists for this species (This is an estimate based on genus-level patterns, no specific development data exists for this species)
• Antkeeping:
  • Temperature: Aim for 22-26°C, New Caledonia is tropical, so they likely prefer warm conditions. A heating cable on one side of the nest can create a gentle gradient if room temperature falls below this range.
  • Humidity: Keep nest substrate moderately moist, think tropical forest floor conditions. The substrate should feel damp but not waterlogged, with some slightly drier areas available.
  • Diapause: Unlikely, as a tropical species from New Caledonia, they probably do not require a hibernation period. However, some reduced activity during cooler months may occur.
  • Nesting: In nature they likely nest in soil or rotting wood, common for small Myrmicines. In captivity, a test tube setup works well for founding colonies. For established colonies, a Y-tong or plaster nest with small chambers scaled to their tiny size is appropriate.
• Behavior: This is a small ant species. They are not known to be aggressive and unlikely to sting humans significantly due to their tiny size. Their small size means they can squeeze through small gaps, excellent escape prevention is essential. They likely forage for small insects and honeydew.
• Common Issues: tiny size makes escape prevention critical, use fine mesh and tight-fitting lids, no specific care documentation exists, keepers must adapt from related species, slow colony growth can lead to beginner impatience and overfeeding, wild-caught colonies may carry parasites that are difficult to detect, humidity control is important, too wet causes mold, too dry causes desiccation

Housing and Nest Setup

For founding colonies, a simple test tube setup works well. Fill a test tube about one-third with water, plug it with cotton, and place the queen in a dark area. The cotton creates a humid chamber that the queen can seal herself into. Once workers arrive, you can transition to a small formicarium. For established colonies, use nests with small chambers and narrow passages scaled to their tiny worker size. Y-tong nests or plaster nests work well. Always ensure excellent escape prevention, these tiny ants can squeeze through gaps that seem impossible.

Feeding and Diet

Based on typical Monomorium behavior, these ants likely accept a varied diet including small insects, honeydew, and sugar sources. Offer sugar water or honey water as a constant carbohydrate source. For protein, small live prey like fruit flies, pinhead crickets, or mealworm pieces work well. Feed protein prey 2-3 times per week, removing any uneaten prey after 24 hours. Since this species is poorly documented, observe what your colony accepts and adjust accordingly.

Temperature and Humidity

As a tropical species from New Caledonia, aim for temperatures in the 22-26°C range. Room temperature within this range is usually sufficient. If your space runs cooler, a heating cable placed on top of (not under) the nest can raise temperatures. Avoid temperatures above 30°C or sudden temperature swings. For humidity, keep the nest substrate moderately moist. In test tube setups, the water reservoir maintains humidity. In formicariums, mist occasionally and monitor for condensation, you want damp but not saturated conditions. Good ventilation helps prevent mold while maintaining humidity.

Colony Development

The queen will seal herself into a chamber and lay eggs after mating. First workers will be smaller than mature workers and may take several weeks to emerge at tropical temperatures. After the first workers arrive, the colony enters a growth phase. Expect gradual growth over several months to years. Be patient, colony development is slow, and overfeeding during early stages can cause mold problems that kill the colony.

Behavior and Temperament

Chelaner croceiventre is likely a docile, non-aggressive species typical of many small Myrmicines. Workers probably forage individually or in small groups, searching for small prey and honeydew. They are not known to sting humans significantly. The main concern for keepers is escape prevention, their tiny size allows them to squeeze through remarkably small gaps. Use fluon on test tube rims, fine mesh on outworlds, and check all connections regularly.
