Lepisiota fergusoni

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Coastal plains of India (Karnataka, Kerala, West Bengal) and Sri Lanka. Found in leaf litter samples and coconut plantations across wet, dry, and intermediate climate zones ^[1][3][2].
• Colony Type: Colony structure is unconfirmed for this specific species.
• Size & Growth:
  • Queen: Size data unavailable for this species
  • Worker: 2-3.5mm ^[4]
  • Colony: Unknown, this species has not been studied in captivity
  • Growth: Unknown
  • Development: Unknown for this species (Development time has not been documented. Tropical ant species typically develop faster than temperate ones.)
• Antkeeping:
  • Temperature: Keep at 24-28°C. These ants come from warm coastal tropical environments in India and Sri Lanka, so they prefer warmer conditions. A heating cable on one side of the nest creates a suitable gradient
  • Humidity: Keep substrate moderately moist. They inhabit leaf litter in coastal areas, so aim for 60-75% humidity. Provide a water tube for drinking water and occasional misting of the outworld
  • Diapause: No true diapause required. As a tropical species from Sri Lanka and coastal India, they do not experience cold winters. Keep them active year-round at stable warm temperatures
  • Nesting: Use a naturalistic setup with leaf litter material or a Y-tong/plaster nest with small chambers. They are ground-dwelling leaf litter ants, so they prefer tight spaces with some moisture-retaining substrate. A test tube setup works for founding colonies
• Behavior: This species is moderately active and forages in the leaf litter layer. They are not particularly aggressive but will defend their nest. Workers are small (2-3.5mm) so escape prevention should focus on fine mesh barriers. They are ground-nesting and likely form moderate-sized colonies. Their small size means they can squeeze through small gaps, use tight-fitting lids and fine mesh on any outworld connections.
• Common Issues: small size makes escape likely without fine mesh barriers, tropical species may decline if temperatures drop below 22°C, limited availability in ant keeping trade, wild-caught colonies may have parasites, ground-dwelling species needs proper substrate depth for nesting, humidity levels that are too low can cause colony decline, the genus Lepisiota is considered exotic to Sri Lanka, ensure you source from legal suppliers

Housing and Nest Setup

Lepisiota fergusoni is a ground-dwelling species that naturally lives in leaf litter and soil. For captive care, a naturalistic setup works best, use a container filled with moist soil or a mixture of soil and leaf litter material. The substrate should be kept moderately moist but not waterlogged. A Y-tong (AAC) or plaster nest with small chambers also works well, especially for established colonies. For founding colonies, a standard test tube setup with a water reservoir works initially, but transfer to a more naturalistic setup once the colony reaches 20-30 workers. These ants prefer tight, enclosed spaces rather than open areas, so provide chambers sized appropriately for their small worker size of 2-3.5mm. ^[1]

Feeding and Diet

Like most Lepisiota species, these ants are omnivorous and will accept both protein and sugar sources. Offer sugar water, honey, or diluted syrup as a constant carbohydrate source. For protein, provide small insects like fruit flies, small mealworms, or other tiny arthropods. In their natural habitat in Sri Lanka and India, they likely forage for small invertebrates and honeydew from aphids in the leaf litter layer. Feed protein prey 2-3 times per week, and keep sugar water available at all times. Remove uneaten prey after 24 hours to prevent mold. ^[1][2]

Temperature and Seasonal Care

As a tropical species from the coastal plains of India and Sri Lanka, Lepisiota fergusoni requires warm temperatures year-round. Maintain nest temperatures between 24-28°C. They do not require hibernation or diapause, keeping them at stable warm temperatures will support continuous colony growth. A small heating cable placed on one side of the nest can help maintain optimal temperatures, especially in cooler climates. Avoid temperatures below 22°C as this species is not adapted to cool conditions. Room temperature in heated homes is often suitable, but monitor with a thermometer. ^[1][3]

Humidity and Water

These ants inhabit leaf litter in coastal areas, so they prefer moderate to high humidity. Keep the nest substrate consistently moist but not waterlogged, the substrate should feel damp but you should not see standing water. Provide a water tube (test tube with cotton plug) as a permanent water source. Occasional light misting of the outworld helps maintain humidity. Good ventilation is important to prevent mold, but avoid excessive airflow that dries out the nest. The combination of moist substrate and adequate ventilation creates the damp forest-floor conditions they naturally inhabit. ^[1]

Colony Development

The colony starts when a queen seals herself in a small chamber and raises her first workers. Since this species has not been studied in captivity, development time is unknown. Initial colonies grow slowly as the queen focuses on producing a small batch of workers. Once established, growth rate depends on temperature and food availability. Maximum colony size is unknown, this species has not been documented in captive colonies. Patience is key during the founding stage.

Behavior and Temperament

Lepisiota fergusoni workers are small but active foragers that search for food in the leaf litter layer. They are not particularly aggressive toward keepers but will defend their nest if threatened. Workers are small enough (2-3.5mm) that they can squeeze through tiny gaps, excellent escape prevention is essential. Use fine mesh on any ventilation holes and ensure all connections between nest and outworld are sealed. The species is ground-dwelling and does not climb smooth surfaces well, but their small size means they can still find unexpected escape routes. They are most active in warm, humid conditions and may become less active if conditions are too dry or cool. ^[1]
