Pheidole macrops

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Based on genus patterns, Pheidole species are typically found in tropical and subtropical regions, nesting in soil, under stones, or in rotting wood ^[1].
• Colony Type: Colony structure is unconfirmed. Many Pheidole species are monogyne (single-queen), but some are polygyne (multiple queens) ^[1].
• Size & Growth:
  • Queen: Size data unavailable for Pheidole macrops, estimated ~5-8 mm based on typical Pheidole queen size ^[1].
  • Worker: Minor workers estimated ~2-3 mm, major workers ~3-5 mm based on genus patterns ^[1].
  • Colony: Up to several thousand workers based on typical Pheidole colony development ^[1].
  • Growth: Moderate, inferred from genus patterns ^[1].
  • Development: Estimated 6-10 weeks at optimal temperature ^[1]. (Development time varies with temperature. Major workers typically appear after the colony reaches several hundred workers.)
• Antkeeping:
  • Temperature: Keep at 22-26°C. Based on genus patterns, Pheidole species thrive in warm, stable conditions ^[1].
  • Humidity: Moderate humidity around 50-70%. Keep nest substrate slightly moist but not waterlogged ^[1].
  • Diapause: Likely not required. Most tropical Pheidole species do not enter true diapause ^[1].
  • Nesting: Test tube setups work well for founding colonies. For established colonies, Y-tong or plaster nests with moderate moisture work well ^[1].
• Behavior: Generally peaceful and non-aggressive. Major workers have powerful jaws but rarely sting. They are primarily granivorous, collecting seeds, and also eat small insects ^[1]. Escape risk is low to moderate, they can climb smooth surfaces, so standard escape prevention is recommended ^[1].
• Common Issues: colonies may stall if temperatures drop below 20°C, keep warm and stable ^[1]., major workers may not appear until the colony is well-established, this is normal ^[1]., overfeeding can lead to mold problems, remove uneaten food promptly ^[1]., test tube setups can dry out, monitor moisture levels and rehydrate as needed ^[1]., wild-caught colonies may contain parasites that can devastate captive colonies ^[1].

Housing and Nest Setup

For founding colonies, a simple test tube setup works well. Fill a test tube one-third with water, plug with cotton, and place the queen in the tube. The cotton should be tight enough to prevent escape but loose enough for movement ^[1]. For established colonies with 50+ workers, a Y-tong or plaster nest provides more space ^[1]. Pheidole macrops does not require elaborate nesting conditions, they do well in test tubes, acrylic nests, or naturalistic setups with soil ^[1]. The outworld should be simple with a foraging area and space for food. Standard escape prevention with fluon on rim edges is recommended ^[1].

Feeding and Diet

Pheidole species are primarily granivorous, meaning they collect and eat seeds. In captivity, offer a variety of seeds including grass seeds, millet, and commercial ant seed mixes ^[1]. They also accept protein sources like small insects (fruit flies, small crickets, mealworms) and will scavenge dead insects ^[1]. Sugar water or honey can be offered occasionally, though seeds are their primary food source. Feed seeds continuously and protein 2-3 times per week. Remove uneaten food promptly to prevent mold ^[1].

Temperature and Seasonal Care

Maintain temperatures between 22-26°C for optimal colony development ^[1]. Pheidole macrops is likely from a tropical or subtropical region and prefers consistent warmth ^[1]. A heating cable placed on one side of the nest can provide a temperature gradient if needed. Avoid temperatures below 18°C for extended periods as this can slow colony growth ^[1]. Unlike temperate species, they likely do not require a true diapause period ^[1].

Colony Development and Castes

Pheidole colonies have two worker castes: minor workers and major workers (soldiers) ^[1]. Minor workers are small, numerous, and handle most tasks including foraging and brood care ^[1]. Major workers have large heads and powerful mandibles for seed processing and defense ^[1]. Major workers typically appear after the colony reaches several hundred workers, which is normal for healthy colonies ^[1]. The development timeline from egg to first worker is estimated 6-10 weeks at optimal temperature ^[1].
