Paratrechina ankarana

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Endemic to northern Madagascar, specifically the Ankarana Special Reserve. Found in dry forest habitats on limestone outcrops at elevations of 80-210 meters. ^[1]
• Colony Type: Unconfirmed, colony structure has not been documented in scientific literature. ^[1]
• Size & Growth:
  • Queen: Estimated ~5-7 mm, inferred from Paratrechina genus patterns. ^[1]
  • Worker: 2.60-2.84 mm total length ^[1]
  • Colony: Unknown, no colony size data available.
  • Growth: Unknown, no development data exists for this species.
  • Development: Estimated 4-8 weeks at optimal tropical temperatures, based on typical small ant patterns. (This is an estimate since no species-specific data exists.)
• Antkeeping:
  • Temperature: Likely 24-28°C, inferred from tropical dry forest habitat. ^[1]
  • Humidity: Dry forest habitat suggests moderate to low humidity. Provide a humidity gradient with a mostly dry nest and one small moist area. ^[1]
  • Diapause: No, tropical species do not require hibernation.
  • Nesting: Prefer tight, enclosed spaces based on limestone habitat. Use small test tube setups or Y-tong nests with narrow chambers. ^[1]
• Behavior: Behavior is unstudied in captivity. Based on genus patterns, they are likely active foragers. Their small size makes escape prevention critical, use fine mesh barriers.
• Common Issues: captive care is uncertain due to limited species data., no established feeding protocols, experiment with small prey and sugar sources., small size requires excellent escape prevention., founding behavior is unconfirmed., tropical species may be sensitive to temperature drops.

Discovery and Distribution

Paratrechina ankarana was described in 2014 by John LaPolla and Brian Fisher. It is known only from the Ankarana Special Reserve in northern Madagascar, a region with limestone karst formations and dry forests. Type specimens were collected at elevations between 80 and 210 meters. ^[1] This limited distribution means it is unlikely to be available in the antkeeping hobby, as wild colonies are in a protected area. ^[1]

Identification and Morphology

Workers are tiny, measuring 2.60-2.84 mm in total length. The cuticle is dark brown with a faint greenish-blue iridescent reflection under magnification. The propodeum has fine striations, while the rest of the body is smooth and shiny. ^[1] They have three small ocelli on the head, which is uncommon in ants. Mandibles have five teeth, with the apical tooth longest. Scapes have short pubescence and abundant standing hairs. ^[1]

Housing and Nesting

Based on dry forest limestone habitat, they prefer tight, enclosed spaces with some humidity control. For their small size, use a small test tube setup or a Y-tong nest with narrow chambers. ^[1] Provide a humidity gradient to match their natural habitat. Escape prevention is critical due to their tiny size, use fine mesh barriers. ^[1]

Feeding and Diet

No specific dietary studies exist for this species. Based on typical Paratrechina behavior, they are likely generalist foragers that collect nectar, honeydew, and small insects. Offer small prey like fruit flies or pinhead crickets, along with sugar sources like honey water. Start with small portions and observe what they accept.

Temperature and Seasonal Care

As a tropical species from Madagascar, keep them warm at 24-28°C year-round. ^[1] Avoid temperatures below 20°C. No diapause is needed. A small heating cable can create a temperature gradient for self-regulation.
