Pheidole bigote

Quick Summary

• Difficulty: Unknown, too little data to assess
• Origin & Habitat: Lowland rainforest in Chiapas, Mexico and Izabal, Guatemala. Nests in clay banks at the edge of small streams in wet forest areas ^[1][2].
• Colony Type: Single-queen colonies (monogyne). Only one colony has been documented, with a single queen found in the lowest chamber ^[1].
• Size & Growth:
  • Queen: size data unavailable
  • Worker: size data unavailable
  • Colony: Unknown, only a single colony has ever been documented ^[1].
  • Growth: Unknown
  • Development: Unknown, no direct data exists. (Based on typical Pheidole patterns in tropical conditions, development may take 4-8 weeks at warm temperatures, but this is an estimate.)
• Antkeeping:
  • Temperature: Keep warm, roughly 24-28°C, based on natural habitat in lowland rainforest ^[1].
  • Humidity: Keep substrate consistently moist but not waterlogged, as the natural nest is near water and prone to flooding ^[1].
  • Diapause: Unknown, likely no true diapause given tropical origin.
  • Nesting: Prefer compact, moisture-retaining substrates like clay or plaster, with horizontal chambers connected by narrow tunnels, as in natural nests ^[1].
• Behavior: Behavior is largely unknown, but as a dimorphic Pheidole, minor workers may forage while majors stay in the nest. Escape risk is moderate due to small worker size, use standard barriers ^[1].
• Common Issues: escape prevention is important, minor workers are tiny and can slip through small gaps, no captive breeding data exists, this species may be difficult to establish from wild-caught queens, high humidity requirements may promote mold growth if ventilation is poor, the nest location near water suggests they need very moist conditions, too-dry conditions could kill the colony, almost no information exists about their diet, offering a variety of protein and sugar sources is recommended

Nest Preferences and Housing

In the wild, Pheidole bigote nests in clay banks at the edge of small streams. The clay is stiff and plastic, like modeling clay, allowing chambers to be carved out. The nest has small entrance holes leading to horizontal chambers at descending levels, with the deepest chamber 12cm below the surface ^[1]. For captive care, use a naturalistic setup with moist, compact substrate like clay or plaster, and design horizontal chambers connected by narrow tunnels to mimic their natural architecture.

Feeding and Diet

The diet is essentially unknown, no observations of feeding behavior exist. The nest excavation found no seeds, suggesting this species does not store seeds despite being in the seed-harvesting tribe Attini ^[1]. For captive care, offer varied protein sources like small insects and sugar sources like honey water, similar to other small Pheidole species.

Temperature and Care

No specific temperature data exists, but the species originates from warm, humid lowland rainforest. Aim for temperatures around 24-28°C with a gentle gradient ^[1]. Humidity should be high, keep the nest substrate consistently moist but not saturated, as the natural nest is prone to flooding.

Colony Structure and Behavior

Pheidole bigote is dimorphic, with minor and major workers. Major workers have unique pompon-like tufts and a facial excavation, but their function is unknown ^[1][4]. Only one colony has been documented, confirming monogyne structure with a single queen. Workers were observed clustering with brood and foraging at bait during day and night ^[1].
