Lepisiota spinosior

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Afrotropical region, documented in Zimbabwe, Mozambique, Eswatini, Nigeria, and Rwanda. Found in grassland and savanna ecosystems. Recorded in both control and rehabilitated grassland sites, indicating adaptability to different habitat conditions ^[2][1].
• Colony Type: Colony structure is unconfirmed for this species. Based on typical Lepisiota patterns, likely single-queen colonies.
• Size & Growth:
  • Queen: Size data unavailable, inferred from Lepisiota genus (~5-8mm)
  • Worker: Size data unavailable, inferred from Lepisiota genus (~3-5mm)
  • Colony: Maximum colony size is unconfirmed, typical Lepisiota colonies reach several hundred workers
  • Growth: Moderate
  • Development: Estimated 6-10 weeks based on related Lepisiota species (Development time is estimated from genus-level data, specific data for L. spinosior is unavailable)
• Antkeeping:
  • Temperature: Keep at 24-28°C based on African savanna species requirements. A slight temperature gradient allows workers to self-regulate. Room temperature in most homes may be slightly cool, consider a heating cable on one side of the nest.
  • Humidity: Moderate humidity around 50-60%. These are grassland ants that tolerate drier conditions than forest species. Allow the nest substrate to dry partially between water additions.
  • Diapause: As an African species, true hibernation is unlikely. Reduced activity during cooler months is possible, but documented behavior is unavailable.
  • Nesting: In nature, they nest in soil, often under stones or in small cavities in the ground. A Y-tong (AAC) nest or test tube setup works well. Provide a small outworld for foraging. Avoid overly moist conditions that can cause mold.
• Behavior: Active foragers that search for food. Workers will defend the nest if threatened. As Formicinae ants, they have access to formic acid for defense. Escape risk is moderate due to their small size, ensure barrier integrity. They are generalist feeders.
• Common Issues: colonies may decline if kept too cold, maintain warm temperatures, small size makes escape prevention important, use fine mesh and proper barriers, limited specific care data means monitoring colony health closely is essential, overfeeding can lead to mold in the nest, remove uneaten food promptly, wild-caught colonies may contain parasites that can devastate captive colonies

Housing and Nest Setup

Lepisiota spinosior can be kept in standard ant keeping setups. A test tube setup works well for founding colonies, with a water reservoir at one end and cotton stoppers. Once the colony reaches 20-30 workers, you can transition to a small formicarium. Y-tong (AAC) nests are excellent for this genus as they provide proper humidity control and allow you to observe the colony easily. For the outworld, a simple plastic container works fine, ensure it has high walls and apply fluon or another barrier to prevent escapes. These ants are moderate escape artists due to their small size. Provide a dark cover over the nest section to encourage the colony to stay inside rather than trying to nest in the outworld.

Feeding and Diet

Like most Lepisiota species, L. spinosior is a generalist feeder. Offer sugar water or honey as a constant energy source, they will readily accept sweet liquids. For protein, provide small insects like fruit flies, pinhead crickets, or mealworms. Some Lepisiota species have symbiotic relationships with Lycaenidae butterflies ^[1], so they may benefit from honeydew sources. Feed protein 2-3 times per week, and keep sugar water available at all times. Remove uneaten prey after 24 hours to prevent mold.

Temperature and Heating

As an African savanna species, Lepisiota spinosior prefers warmer conditions. Keep the nest area at 24-28°C for optimal colony development. Room temperature (20-24°C) may be acceptable but could slow growth and activity. Use a heating cable or heating mat on one side of the nest to create a temperature gradient, this allows workers to move to warmer or cooler areas as needed. Place the heating on top of the nest, not underneath, to avoid drying out the substrate too quickly. Monitor for excessive drying, especially when using active heating.

Humidity and Water

Maintain moderate humidity in the nest, aim for around 50-60% relative humidity in the substrate. These are grassland ants that naturally experience drier conditions than forest species. The nest substrate should be moist but not waterlogged. Allow the surface to dry slightly between water additions rather than keeping it constantly wet. A water tube in the outworld provides drinking water. Mist the outworld occasionally to encourage foraging activity, but avoid excessive moisture in the nest area.

Behavior and Defense

Lepisiota species are known for their active defense behaviors. Workers will defend the nest against threats. As Formicinae ants, they can produce formic acid as a defensive secretion. They are active foragers that search the outworld for food throughout the day. The colony will establish clear foraging trails once they find reliable food sources. Their small size and active nature make them entertaining to watch.

Colony Development

A newly mated queen will seal herself in a small chamber and lay eggs. She will not leave to forage during founding, instead she uses stored fat reserves to survive and feed the first brood. The first workers (nanitics) will be smaller than mature workers but will immediately begin helping the queen. Colony growth is moderate, expect several months before you have a significant number of workers. The colony will expand its nest if given space and may produce alates (reproductives) in subsequent years. Growth rate depends heavily on temperature and feeding frequency.
