Pheidole quinata

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Borneo, Indonesia, and Malaysia in the Indomalaya region. These ants live in hill forests at elevations around 1000 m, nesting in soil and leaf litter on the forest floor ^[1].
• Colony Type: Colony structure is unconfirmed for this species. Most Pheidole species are monogyne (single queen), but this has not been specifically documented for P. quinata.
• Size & Growth:
  • Queen: Size data unavailable for queens, inferred from Pheidole genus patterns to be larger than workers
  • Worker: Major workers: 5.0 mm, Minor workers: 2.5-2.7 mm ^[1]
  • Colony: Colony size data unavailable, estimated from typical Pheidole colonies to be up to several thousand workers
  • Growth: Moderate
  • Development: Unknown, based on tropical Pheidole patterns, estimated 5-8 weeks at 24-28°C (Development time inferred from genus-level data for tropical Pheidole species)
• Antkeeping:
  • Temperature: Keep warm, roughly 24-28°C, based on tropical habitat conditions ^[1]. Use a heating cable to create a gradient if needed.
  • Humidity: Maintain moderate to high humidity with consistently moist but not waterlogged substrate, as forest floor species require damp conditions ^[1].
  • Diapause: Unknown, tropical species from consistent climate may not require diapause, but slight temperature reduction in cooler months is tolerated.
  • Nesting: Natural nesting in soil and leaf litter ^[1]. In captivity, use moist substrate mixes or Y-tong/plaster nests with good moisture retention.
• Behavior: These ants are generally non-aggressive but will defend their colony if threatened. Major workers serve as soldiers and can deliver a mild sting, though this is barely noticeable to humans due to their small size. Minor workers are very small (2.5 mm), so escape prevention is important, they can squeeze through small gaps. They are active foragers on the forest floor.
• Common Issues: humidity management is critical, too dry and colonies will fail, too wet and mold becomes a problem., wild-caught colonies may contain parasites that can decimate the colony in captivity., small minor workers can get lost if the nest setup lacks proper moisture gradients., tropical species are sensitive to temperature drops, keep away from cold drafts., Pheidole colonies can grow large quickly, ensure you have space for expansion.

Nest Preferences and Housing

In the wild, Pheidole quinata nests in soil and leaf litter on the forest floor of hill forests in Borneo ^[1]. They prefer dark, humid microhabitats with stable temperatures. For captive care, use a mixture of soil and peat or coco fiber as substrate, kept consistently moist but not waterlogged. A depth of 5-10 cm allows them to create brood chambers. Alternatively, a Y-tong nest with narrow chambers and good moisture retention works well. Maintain high humidity with adequate ventilation to prevent mold. Place the nest in a dark area or cover three sides to simulate their natural environment.

Feeding and Diet

Pheidole quinata is a generalist omnivore like most Pheidole species. They accept protein sources including small insects such as fruit flies and pinhead crickets, and they also collect seeds. Offer protein prey 2-3 times per week and provide a constant sugar source like sugar water or honey. Remove uneaten prey after 24-48 hours to prevent mold. Prey items should be appropriately sized for their small workers.

Temperature and Seasonal Care

As a tropical species from Borneo, P. quinata requires warm conditions year-round. Maintain temperatures between 24-28°C for optimal brood development ^[1]. Temperatures below 22°C may slow activity, while above 32°C can be stressful. Use a heating cable on one side of the nest to create a gradient if room temperature is low. Unlike temperate species, they do not require a true hibernation diapause, but slight seasonal variations are tolerated.

Colony Founding

The colony founding behavior of P. quinata has not been directly documented. Founding colonies should be kept in complete darkness with minimal disturbance. After the first workers emerge, the colony will expand as the queen continues laying eggs and foragers bring food back to the nest.

Behavior and Defense

Pheidole quinata has distinct worker castes: large major workers (soldiers) and smaller minor workers (foragers). Majors are about 5 mm and serve colony defense, while minors at 2.5 mm handle foraging and brood care. When disturbed, majors may emerge to defend the colony. The sting is mild due to their small size and is rarely felt by humans. They are not aggressive toward keepers but will defend their nest territory. ^[1]
