Cephalotes trichophorus

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Amazonian rainforests of Brazil (Acre, Amazonas), Ecuador (Orellana province), and Peru (Madre de Dios) ^[3][1]. Found in lowland tropical rainforest at elevations up to 120m. Collected from canopy using fogging techniques, indicating they are arboreal (tree-dwelling) ants ^[3].
• Colony Type: Colony structure is unconfirmed for this species. The soldier caste is currently unknown for this species and other coffeae group members ^[4].
• Size & Growth:
  • Queen: Undescribed, queen size unknown for this species
  • Worker: 3.18mm total length ^[1]
  • Colony: Unknown for this specific species
  • Growth: Unknown, no species-specific growth data exists
  • Development: Unknown for this species (Development time is unconfirmed. Tropical Cephalotes species typically develop faster than temperate ants, but no specific data exists for this species.)
• Antkeeping:
  • Temperature: Keep at 24-28°C (tropical warmth). Avoid temperatures below 20°C, these are true tropical ants.
  • Humidity: High humidity (70-85%) is essential. These are rainforest ants that naturally experience constant moisture. Keep nest substrate consistently damp but not waterlogged. Provide a water tube as a humidity source.
  • Diapause: No, this is a tropical species from Amazonian rainforests. They do not require hibernation or winter rest. Maintain warm conditions year-round.
  • Nesting: Arboreal setup is ideal. Use a Y-tong (AAC) nest or a naturalistic setup with twigs/branches. They prefer tight, enclosed chambers that mimic their natural hollow twig nesting sites. Avoid large open spaces, these are small ants that feel secure in compact nests.
• Behavior: Docile and slow-moving. Like other Cephalotes, they are not aggressive. They possess a functional stinger but it is less medically significant to humans than fire ant stings. Workers are generalist foragers, likely collecting honeydew from aphids and small insects in the wild. Escape risk is moderate, their small size means they can slip through small gaps, but they are not strong climbers like some arboreal species.
• Common Issues: tropical temperature requirements mean cold rooms will kill colonies, must use heating if ambient is below 24°C, high humidity needs can lead to mold if ventilation is poor, balance moisture with airflow, arboreal nature means they need vertical space and branches, horizontal-only nests may stress them, very limited biological data means keepers are essentially pioneering care for this species, no species-specific data on founding behavior, wild colonies may be difficult to establish

Housing and Nest Setup

Cephalotes trichophorus is an arboreal species, so your setup should reflect their natural tree-dwelling lifestyle. A Y-tong (AAC) nest works well because it provides the tight, enclosed chambers these ants prefer. The chambers should be appropriately sized for their small 3mm workers, avoid large, open spaces that can make them feel insecure.

For a more naturalistic approach, you can create a setup with small twigs or branches containing pre-drilled holes for nesting. The key is providing vertical space and the ability to climb. They do not need soil or substrate like ground-nesting ants, a dry outworld with a water tube for humidity is sufficient. Make sure all connections between the nest and outworld are smooth and climbable, as these small ants are not strong climbers on slippery surfaces. Escape prevention should be moderate, they can fit through very small gaps but are not particularly active escape artists. ^[1]

Feeding and Diet

Like other Cephalotes species, these ants are generalists that feed on honeydew (the sugary liquid aphids produce) and small insects. In captivity, offer sugar water or honey water as a constant energy source. For protein, provide small prey items like fruit flies, pinhead crickets, or small mealworms. Since they are small, prey items should be appropriately sized, no larger than their own body size.

Feed sugar sources continuously (check and replace every few days) and offer protein 2-3 times per week. Remove any uneaten prey after 24-48 hours to prevent mold. Because nothing specific is known about this species' diet, observe your colony's preferences and adjust accordingly. ^[1]

Temperature and Humidity

These are true tropical ants from Amazonian rainforests, so warmth is essential. Keep the nest area at 24-28°C consistently. Temperatures below 20°C will stress and potentially kill colonies. A small heating cable or mat on one side of the nest can create a gentle gradient, but always provide unheated areas so ants can regulate their own temperature.

Humidity should be high, aim for 70-85%. In a Y-tong nest, a water tube connected to a cotton reservoir provides humidity through evaporation. The nest material should feel consistently damp but never have standing water. Mist the outworld occasionally, but avoid getting the nest itself too wet. Good ventilation is important to prevent mold while maintaining humidity. ^[1]

Behavior and Colony Life

Cephalotes trichophorus is a docile species. Their primary defense is a functional stinger, though it is less medically significant to humans than fire ant stings. They also have the characteristic flattened, shield-like head typical of the genus, which workers can use to block nest entrances. They are slow-moving and not aggressive toward keepers.

Colony growth rate is unknown for this species, Cephalotes colonies can reach several hundred workers under good conditions, but specific data for C. trichophorus does not exist. The queen (when discovered) will be larger than workers and should be handled gently during colony founding. Since almost nothing is known about this species' founding behavior, expect some experimentation may be needed to establish wild-caught colonies. ^[4]
