Monomorium elghazalyi

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Socotra Archipelago, Yemen, an island in the Indian Ocean with a subtropical climate. They nest in moist soil under rocks next to date palm trees and forage in dry, organic-rich soil ^[1]. Endemic to Socotra ^[1].
• Colony Type: Colony structure is unconfirmed.
• Size & Growth:
  • Queen: Not yet described in scientific literature
  • Worker: 1.8-2.2mm ^[1]
  • Colony: Unknown
  • Growth: Unknown
  • Development: Unconfirmed (No development data exists for this species.)
• Antkeeping:
  • Temperature: Keep warm, around 24-28°C. Socotra has a subtropical climate with year-round warmth.
  • Humidity: Provide moderate humidity with a moist nest area and drier foraging areas. In the wild, they nest in moist soil under rocks but forage in very dry areas ^[1]. Keep the nest substrate damp but not waterlogged.
  • Diapause: Unknown, Socotra has minimal seasonal temperature variation. They likely do not require a true diapause.
  • Nesting: Use a test tube setup or small formicarium with tight chambers scaled to their tiny size. They prefer moist soil substrates.
• Behavior: These are tiny, docile ants. They possess a sting but due to their very small size (under 2.2mm), they are unlikely to sting humans effectively. Workers are active foragers that search for small food items. Their tiny size means escape prevention is critical, they can squeeze through standard mesh barriers. Use fine mesh or fluon barriers to prevent escapes.
• Common Issues: tiny size means escapes are likely without fine mesh barriers, no published care information exists, keepers must experiment with conditions, founding colonies are fragile and require stable humidity, limited availability since the species was only described in 2017

Housing and Setup

Monomorium elghazalyi requires housing scaled to their tiny size. Workers measure only 1.8-2.2mm, so standard test tube setups work well for founding colonies. Use test tubes with cotton and a water reservoir, the tube should be small enough that the colony feels secure. For established colonies, a small formicarium with tight chambers and narrow connections works better than large, open spaces. These ants are not escape artists in the traditional sense, but their tiny size allows them to squeeze through gaps that larger ants cannot. Apply fluon to the edges of any outworld or use fine mesh on all ventilation holes. A hybrid setup combining a test tube for the nest chamber and a small outworld for foraging is ideal for starting colonies. The nest area should have moist substrate while the outworld remains dry. ^[1]

Feeding and Diet

In the wild, these ants have been found foraging in soil rich in decaying goat faeces under date palm trees, suggesting they are scavengers that exploit small organic particles ^[1]. In captivity, offer small protein sources like fruit flies, pinhead crickets, or small mealworms. Due to their tiny size, prey items should be appropriately scaled, flightless fruit flies are an excellent choice. They likely accept sugar sources, though this is unconfirmed. Offer a small drop of honey or sugar water alongside protein foods. Feed small amounts 2-3 times per week, removing uneaten prey after 24 hours to prevent mold. The key is offering appropriately-sized food, these ants cannot tackle large prey items.

Temperature and Humidity

Socotra Island has a subtropical climate with warm temperatures year-round. Keep your colony at 24-28°C for optimal activity and development. A heating cable placed on one side of the nest creates a gradient that allows ants to self-regulate their temperature. For humidity, provide a moist nest area, the substrate should feel damp but not soggy. In the wild, they nest in moist soil under rocks but forage in very dry areas ^[1]. This suggests they benefit from a humidity gradient within their setup. The outworld can be kept relatively dry while the nest chamber maintains moisture. Monitor for condensation, some moisture is good but excessive water can drown small colonies.

Colony Establishment

Since this species was only described in 2017,captive breeding information is extremely limited. Queens have not yet been described scientifically, so wild-caught founding colonies are the primary source for keepers. When acquiring a founding colony, transfer it to a test tube setup with moist cotton as the nest substrate. Place the setup in a dark, quiet location and avoid disturbing the colony for the first few weeks. The queen (if present) will seal herself in a chamber and lay eggs. Do not feed during the founding stage, the claustral queen (if this species follows typical Monomorium patterns) will have sufficient fat reserves to raise her first workers. Once the first workers emerge, you can begin offering tiny food items. Growth will likely be slow initially as the colony establishes itself. ^[1]

Seasonal Care

Socotra Island experiences minimal seasonal temperature variation, with temperatures ranging from 20-28°C throughout the year. This species may not require a traditional hibernation or diapause period. However, during winter months in temperate climates, you may reduce temperatures slightly to 20-22°C to match natural seasonal cues. Do not cool them dramatically, a slight reduction is sufficient if desired. Some keepers report that reducing temperatures during winter helps trigger spring activity in tropical species. Monitor your colony's behavior, if they remain active year-round at room temperature, no cooling is necessary. Avoid temperatures below 18°C as this could stress the colony.
