Lepisiota dammama

Quick Summary

• Difficulty: Unknown, likely Easy to Medium based on genus patterns
• Origin & Habitat: Endemic to Saudi Arabia, specifically the Dammam region along the Persian Gulf coast (26°24'N 50°11'E). Found in arid, desert-adjacent habitats with typical Arabian Peninsula climate, extremely hot summers and mild winters ^[2][1][3].
• Colony Type: Unconfirmed, likely monogyne (single queen) based on typical Lepisiota patterns. No data on colony structure for this specific species.
• Size & Growth:
  • Queen: Size data unavailable for this species, inferred from genus patterns (~5-8mm)
  • Worker: Approximately 4-5mm based on genus typical size
  • Colony: Unknown, likely moderate based on typical Lepisiota colony sizes
  • Growth: Unknown, likely moderate growth rate typical of the genus
  • Development: Unconfirmed, estimated 4-8 weeks based on typical Formicinae development in warm conditions (No direct development data exists for this species. Estimate based on typical Formicinae development in warm conditions (25-30°C).)
• Antkeeping:
  • Temperature: Keep warm, aim for 24-30°C based on their Saudi Arabian origin. A heating cable on one side of the nest creates a temperature gradient allowing ants to self-regulate. Room temperature in heated homes (22-25°C) may be acceptable.
  • Humidity: Low to moderate, these are desert-adapted ants. Keep the nest substrate relatively dry with only occasional light misting. Allow the substrate to dry between water additions. Avoid damp conditions that could cause mold.
  • Diapause: Likely minimal or no true diapause, Saudi Arabia has mild winters. However, a brief cool period (15-18°C for 4-6 weeks) during winter months may benefit colony health, similar to other Palearctic species.
  • Nesting: In nature they likely nest in soil or under stones in arid ground. For captivity, a Y-tong (AAC) nest or plaster nest works well. Avoid overly humid setups. Provide a small outworld for foraging.
• Behavior: Behavior is unstudied, but Lepisiota species are typically moderate in temperament, not particularly aggressive but will defend the nest. Workers are active foragers. Escape risk is moderate due to their small size, use standard barriers. They likely accept sugar water and small insects as food, similar to related species.
• Common Issues: no biological data exists for this species, keepers must learn through observation, extreme rarity in the wild means no established captive breeding lines, desert origin means overwatering or high humidity can quickly kill colonies, small size creates moderate escape risk, use proper barriers, lack of species-specific information means temperature and feeding preferences are estimates

Appearance and Identification

Lepisiota dammama workers are small ants measuring approximately 4-5mm. They have a distinctive bicolored appearance that helps separate them from related species, the head is a brilliant black, the rear body section (gaster) is brownish, and the middle body shows a mix of pale red and dark areas. Their most distinguishing features are the sharp, pointed spines on the propodeum (rear of the middle body) and the petiole (the narrow waist segment). They also have notably large eyes and a more shining (glossy) appearance compared to similar species like Lepisiota frauenfeldi. The antennae and legs are pale in color ^[1]. These ants belong to the subfamily Formicinae and tribe Plagiolepidini.

Natural Distribution and Habitat

This species is endemic to Saudi Arabia, meaning it's found nowhere else in the world ^[2]. The type specimens were collected from Dammam, a city on the Persian Gulf coast (26°24'N 50°11'E), as well as Jebel Maniq and Wadi Awsat ^[1]. It's considered a rare species, only about 5 specimens have been documented in scientific collections ^[2]. The species has Palearctic zoogeographic affinities, connecting it to ant faunas found in regions north of the Arabian Peninsula ^[2]. In their natural habitat, they likely nest in soil or under stones in arid ground, adapting to the extreme heat and dryness of the Arabian Desert region.

What We Don't Know

It's important to be upfront: literally nothing has been published about the biology of Lepisiota dammama. We don't know their colony structure (single queen or multiple), founding behavior (how queens start new colonies), development time, diet preferences, or any aspects of their behavior in captivity. This is one of the least-studied ant species in the hobby. What we can do is apply what we know about the genus Lepisiota as a whole and about other ants from the Arabian Peninsula region. Keepers of this species will essentially be pioneers, learning about its care through observation and experimentation. ^[1]

Housing and Nesting

Based on their desert origin, provide a relatively dry nest environment. A Y-tong (AAC) acrylic nest or plaster nest works well, both allow you to control humidity levels more easily than fully naturalistic setups. Keep the nest relatively dry with only occasional light misting if the substrate appears to be drying out completely. Allow periods of dryness between water additions to prevent mold growth, which can quickly kill desert-adapted ants. The outworld can be decorated with sand or gravel appropriate for an arid species. Ensure excellent escape prevention, while not the smallest ants, they can still squeeze through small gaps.

Temperature and Heating

As a species from Saudi Arabia, Lepisiota dammama likely prefers warm conditions. Aim for a temperature range of 24-30°C in the nest area. A heating cable placed on one side of the nest creates a temperature gradient, allowing the ants to move to warmer or cooler areas as they prefer. During summer months, room temperature in heated homes (22-25°C) may be adequate. In winter, a slight reduction to around 18-22°C is reasonable, but avoid cold temperatures below 15°C. The key is stability, avoid sudden temperature swings.

Feeding and Diet

No specific feeding data exists for this species, but Lepisiota ants are typically omnivorous. Offer sugar water or honey as an energy source, small test tubes with cotton balls soaked in sugar water work well. For protein, provide small insects like fruit flies, small mealworms, or cricket pieces. Given their small size, prey items should be appropriately sized. Observe what the colony accepts and adjust accordingly. Feed protein 2-3 times per week and keep sugar water available constantly. Remove any uneaten prey after 24-48 hours to prevent mold.
