Pheidole peguensis

Quick Summary

• Difficulty: Easy
• Origin & Habitat: Myanmar (Burma) in the Indomalaya region. No specific habitat data are available, inferred from the genus: likely tropical or subtropical areas, nesting in soil or under stones at ground level ^[1].
• Colony Type: Unconfirmed. Most Pheidole species are monogyne (single‑queen), but no specific data confirm this for Pheidole peguensis.
• Size & Growth:
  • Queen: Size unknown, inferred from Pheidole genus: ~5-7 mm
  • Worker: Size unknown, inferred from Pheidole genus: minor workers ~2-3 mm, majors ~3-4 mm
  • Colony: Up to several thousand workers (inferred from Pheidole genus patterns)
  • Growth: Moderate to fast (inferred from genus)
  • Development: Estimated 6-8 weeks at warm temperatures (based on typical Pheidole development, inferred) (Development is temperature‑dependent, warmer conditions (24-28°C) accelerate it, cooler temperatures slow it down.)
• Antkeeping:
  • Temperature: Likely 24-28°C, based on its tropical origin (inferred). Provide a gradient with a heating cable so the ants can choose.
  • Humidity: Moderate. Keep the nest substrate lightly moist but not waterlogged. This is typical for many Pheidole (inferred).
  • Diapause: No, as a tropical species, no hibernation is required. Keep temperatures above 15°C year‑round (inferred from origin).
  • Nesting: Founding can be done in a test tube. Once the colony reaches 30-50 workers, transfer to a Y‑tong, plaster, soil, or 3D‑printed formicarium. Avoid acrylic nests. Ensure the nest has dark chambers and is connected to an escape‑proof outworld (inferred from genus).
• Behavior: Minor workers handle foraging, brood care, and nest maintenance. Majors specialize in defense and processing large food. Majors can deliver a mild sting. Workers are small (~2-4 mm), so escape risk is high, they can climb smooth surfaces, so use fluon or similar barriers on rims. Activity likely crepuscular/nocturnal (inferred from Pheidole genus). Not particularly aggressive unless the nest is threatened.
• Common Issues: mold growth from overfeeding or excessive moisture, remove uneaten food after 24-48 hours., queen death during founding, keep the founding setup dark and undisturbed at 24-28°C., colony growth stalls if temperatures are too low, maintain warmth for active development., high escape risk due to small size, check all connections and use escape‑proof barriers., monogyne colony, do not attempt to combine queens, keep each in its own setup.

Taxonomic Note

Pheidole peguensis was originally described by Emery in 1895 as a subspecies of P. latinoda from Myanmar. Forel raised it to species status in 1902 ^[1]. However, a revision of Northern Vietnamese Pheidole by Eguchi (2008) ^[2] determined that P. peguensis is a junior synonym of Pheidole plagiaria. This means the ant formerly known as P. peguensis is now considered the same species as P. plagiaria. For antkeeping purposes, care requirements are identical to other Pheidole species, particularly P. plagiaria and related members of the genus (inferred).

Housing and Nest Setup

For founding colonies, a simple test tube setup works well: fill one‑third with water, plug with cotton, and place the queen inside. Keep it dark and undisturbed for 4-6 weeks until the first workers (nanitics) emerge. Once the colony reaches 30-50 workers, move them to a formicarium. Y‑tong (AAC), plaster, soil, or 3D‑printed nests are suitable. Avoid acrylic nests. Connect the nest to an escape‑proof outworld. Use fluon or petroleum jelly on edges to prevent escapes (inferred from typical Pheidole care).

Feeding and Diet

Pheidole peguensis is likely a generalist seed‑harvester, typical of the genus. Offer a varied diet: seeds (millet, chia, cracked sunflower) constantly, protein (small insects like fruit flies, pinhead crickets) 2-3 times per week, and sugar water or honey occasionally. Major workers help process larger food. Remove uneaten protein within 24-48 hours to prevent mold. Provide fresh water via a water tube or moist cotton (inferred from genus).

Temperature and Seasonal Care

As a tropical species, Pheidole peguensis thrives at 24-28°C (inferred from origin). Room temperature (20-24°C) is tolerated but slows growth. Do not allow temperatures below 15°C. Use a heating cable on one side of the nest to create a gradient. No hibernation is required, keep warm year‑round (inferred).

Colony Development

Founding behavior is unconfirmed for this species, but based on typical Pheidole, the queen likely founds claustrally, relying on stored reserves until the first workers eclose. The first workers (nanitics) are smaller than mature minors. Colony growth is moderate to fast under optimal conditions, reaching several thousand workers in 1-3 years. The development of major workers usually begins when the colony passes a few hundred workers. Egg‑to‑worker time is estimated at 6-8 weeks at 24-28°C (inferred from genus).

Behavior and Interaction

Minor workers forage, tend brood, and maintain the nest. Majors defend the colony and help process large items. They can deliver a mild sting if handled. Workers are small (estimated 2-4 mm), so escape risk is high, they can climb smooth surfaces, use fluon or similar barriers. Activity is likely crepuscular or nocturnal, typical of many Pheidole (inferred). They are not normally aggressive toward humans.
