Carebara quratulain

Quick Summary

• Difficulty: Expert
• Origin & Habitat: Salim Ali Bird Sanctuary, Kerala, India (10°45′N, 76°44′E, 118m elevation). Lowland evergreen forest between branches of Periyar River, the richest bird habitat in peninsular India. Annual rainfall approximately 3000mm, supporting teak, rosewood, mahogany and diverse vegetation. Collected from leaf litter on forest floor near a teak tree ^[1].
• Colony Type: Unconfirmed colony structure. Only major workers have been described, queen caste unknown.
• Size & Growth:
  • Queen: Unknown, queen caste has not been described in scientific literature ^[1]
  • Worker: Approximately 1-2mm total length, inferred from Carebara genus patterns ^[1]
  • Colony: Unknown, colony size has not been documented
  • Growth: Unknown, development timeline has not been studied
  • Development: Unconfirmed, no direct observations of development (Direct observations from this species are needed for accurate timelines.)
• Antkeeping:
  • Temperature: Inferred: Keep warm, around 24-28°C. The species comes from a tropical lowland evergreen forest in Kerala where temperatures remain warm year-round. Provide a gentle temperature gradient allowing ants to self-regulate ^[1].
  • Humidity: High humidity required. The natural habitat receives approximately 3000mm annual rainfall, indicating consistently moist conditions. Keep nest substrate damp but not waterlogged. Provide a moisture gradient so ants can self-regulate ^[1].
  • Diapause: Unknown, no data on overwintering requirements. Kerala has mild winters with temperatures rarely dropping below 20°C, so a true diapause may not be necessary. Observe colony behavior and adjust accordingly.
  • Nesting: Inferred: Subterranean species that naturally nests in soil and leaf litter. In captivity, use a setup that maintains high humidity and darkness. Y-tong (AAC) nests or plaster nests with small chambers work well. Keep nesting area dark and humid. Test tubes with cotton can work for founding colonies if humidity is maintained ^[1].
• Behavior: Behavior is poorly documented. As a subterranean Carebara species, they likely remain mostly hidden within the nest or foraging in covered areas. Their tiny size (approximately 1-2mm for major workers) means escape prevention is critical, they can squeeze through extremely small gaps. Use fine mesh barriers and ensure all connections are sealed. Aggression levels are unknown but likely moderate like most Carebara species. They are probably nocturnal or crepuscular foragers based on their very small eyes ^[1]. Defense mechanism: smear (using modified stinger to wipe venom onto enemies), typical for Myrmicinae subfamily.
• Common Issues: tiny size makes escape prevention critical, they can squeeze through gaps smaller than 1mm, limited data means care requirements are largely inferred from genus patterns, not confirmed for this species, high humidity needs can lead to mold problems if ventilation is inadequate, only major worker caste known, colony structure and queen behavior unconfirmed, rare in captivity with no established breeding populations, wild-caught colonies may have collection stress

Discovery and Description

Carebara quratulain was only described in 2017 by Akbar and Bharti, making it one of the most recently described ant species in India. The species name comes from Arabic, meaning 'pleasure to eyes,' referring to the beautiful appearance of these ants. The type specimens were collected from the Salim Ali Bird Sanctuary in Kerala, one of the richest bird habitats in peninsular India, at an elevation of 118 meters. The specimens were collected using hand-picking methods from leaf litter on the forest floor near a teak tree. This species is considered to be of rare occurrence, as it was encountered only once during extensive ant surveys in the Western Ghats region ^[1].

Identification and Morphology

Carebara quratulain can be identified by several unique features. The posterior margin of the head is strongly concave (curved inward), and there is a single medium ocellus (simple eye) present on the back of the head. The eyes are extremely small, containing only a single ommatidium (light-catching unit), which is unusual among ants. In side view, the head has a pair of small but well-developed pointed horns. The antennae have 9 segments with a 2-segmented club. The body is brown with a yellowish head and darker abdomen, covered in abundant erect to semi-erect hairs. These ants are among the smallest ants in the world, with major workers measuring approximately 1-2mm in total length, inferred from Carebara genus patterns ^[1].

Natural Habitat

This species is known only from the lowland evergreen forests of Kerala, India, in the Salim Ali Bird Sanctuary area located between the branches of the Periyar River. The region receives approximately 3000mm of rainfall annually and supports diverse vegetation including teak, rosewood, and mahogany plantations. The ants were collected from leaf litter on the forest floor, indicating they are a subterranean species that lives and forages underground or under cover. The high rainfall and dense forest cover create a consistently warm and humid environment year-round. This species has not been found in any other location despite extensive surveying ^[1].

Housing and Care

Since Carebara quratulain is a newly described species with limited data, care recommendations are based on inferred genus patterns rather than confirmed observations. These ants require high humidity, think damp forest floor conditions. Keep the nest substrate consistently moist but not waterlogged, and provide a humidity gradient so ants can self-regulate. Temperature should be warm, in the range of 24-28°C, reflecting their tropical origin in Kerala. Because they are subterranean, they prefer darker nesting areas. For founding colonies, a test tube setup with a water reservoir can work if you maintain high ambient humidity around it. For established colonies, Y-tong or plaster nests with small chambers scaled to their tiny size work well. Escape prevention is critical due to their extremely small size, use fine mesh and seal all gaps ^[1].

Feeding and Diet

The diet of Carebara quratulain has not been documented in scientific literature. Based on typical Carebara genus behavior, they are likely omnivorous, feeding on small insects, honeydew, and organic matter in the soil. In captivity, you should offer small protein sources like fruit flies, springtails, or other tiny arthropods. Sugar sources may be accepted but are not a primary food source for most subterranean Carebara species. Feed small amounts of protein every few days and remove uneaten food to prevent mold. Since they are subterranean foragers, they may prefer to hunt or scavenge in darker areas of the nest ^[1].
