Pheidole maja

Quick Summary

• Difficulty: Hard
• Origin & Habitat: Guatemala, specifically the highlands around Guatemala City and Tecpam at approximately 7000 feet (2135m) elevation ^[1][3].
• Colony Type: Unconfirmed, no data on colony structure
• Size & Growth:
  • Queen: 6.2 mm ^[2]
  • Worker: Major workers: 3.5-3.8 mm, minor workers: 2.3 mm ^[2]
  • Colony: Unknown, no data exists
  • Growth: Unknown
  • Development: Unknown, no data exists (Development timeline is unconfirmed for this species)
• Antkeeping:
  • Temperature: Based on highland origin, keep at room temperature with a gradient. Start around 20-24°C and observe colony activity ^[2][3].
  • Humidity: Keep nest substrate lightly moist but not waterlogged, with a humidity gradient ^[2].
  • Diapause: Unknown, no data on overwintering requirements
  • Nesting: No specific nesting data. Use test tubes for founding and Y-tong or plaster nests for established colonies, with escape prevention due to small size ^[2].
• Behavior: No behavioral observations published. Based on genus patterns, Pheidole species are typically active foragers. Defense involves a stinger as a member of Myrmicinae, but no specific data for this species. Escape risk is high due to small worker size ^[2].
• Common Issues: no biological data means care is speculative, monitor colony health closely, escape prevention is critical due to small worker size, use fine mesh barriers, lack of colony size data makes housing upgrades uncertain, observe for crowding, no confirmed diet preferences, offer varied foods and note acceptance, founding behavior is unconfirmed, assume claustral as default for Pheidole

Appearance and Identification

Pheidole maja is a dimorphic ant with two worker castes: major workers (soldiers) and minor workers. Major workers measure 3.5-3.8 mm in length and have an elliptical head that narrows from above. Minor workers are about 2.3 mm and more robust. The coloration is uniform chestnut brown, with paler legs, antennae, and mandibles. The species belongs to the fallax group and was described by Forel in 1886 ^[2][1].

Natural History and Distribution

This species is known only from Guatemala, specifically highland locations around Guatemala City and Tecpam at 7000 feet elevation. No biological data exists on nesting habits, diet, or behavior in the wild ^[2][3][4].

Housing and Nest Setup

For founding colonies, use a standard test tube setup. For established colonies, use Y-tong or plaster nests with chambers scaled to their small size. Escape prevention is critical due to the 2.3 mm minor workers, use fine mesh on all openings ^[2].

Feeding and Diet

No specific dietary data exists. Offer protein sources like small insects, seeds, and sugar water. Observe what the colony accepts and adjust accordingly ^[2].

Temperature and Seasonal Care

Based on highland origin, keep at room temperature with a gradient around 20-24°C. Monitor colony behavior to adjust. Diapause requirements are unknown ^[2][3].

Challenges and Considerations

The main challenge is the lack of biological data, requiring close observation. Escape prevention is essential due to small size. This species is rarely kept, so care guidelines are limited ^[1][2].
