Pheidole diversipilosa

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Southwestern Texas to mountains of southern and central Arizona, also in Mexico. They live in oak-pine-juniper forests at 1050-1900m elevation, especially in creek valleys. ^[1]
• Colony Type: Monogyne (single-queen colonies). Colonies have one queen and can grow large. ^[1]
• Size & Growth:
  • Queen: Size data unavailable.
  • Worker: Size data unavailable.
  • Colony: Up to 1000 workers in mature colonies. ^[1]
  • Growth: Moderate, based on typical Pheidole development patterns.
  • Development: Estimated 6-8 weeks at optimal temperature, based on Pheidole genus patterns. (Brood is found in nests starting in April, with sexuals appearing in June. ^[1])
• Antkeeping:
  • Temperature: Keep around 22-26°C with a gentle gradient, as they come from mid-elevations. ^[1]
  • Humidity: Keep substrate moderately moist but not waterlogged, with some drier areas. ^[1]
  • Diapause: Based on geographic range, likely requires winter diapause. Reduce temperatures to 10-15°C for 2-3 months during winter.
  • Nesting: Naturalistic setup with soil substrate and flat stones, or Y-tong/plaster nests with chambers scaled to colony size. ^[1]
• Behavior: Pheidole diversipilosa is aggressive in resource discovery but vulnerable to phorid fly parasitoids, which restrict foraging. Workers are attracted to protein baits like tuna. They are not highly aggressive toward keepers but will defend the nest. Escape risk is moderate due to small worker size. ^[2][3][1]
• Common Issues: phorid fly attacks can weaken colonies and reduce foraging activity., mold growth from seed caching if food is overprovided., escape risk due to small worker size.

Nest Preferences and Housing

In the wild, Pheidole diversipilosa nests under rocks and in open soil within oak-pine-juniper forests. For captive care, use a naturalistic setup with soil-based substrate to allow digging. Place flat stones on the surface for shelter. Y-tong or plaster nests with appropriate chambers work well. Provide a moisture gradient with drier areas, as colonies can exceed 1000 workers and need space for expansion. ^[1]

Feeding and Diet

This species is omnivorous with a strong preference for protein. Foragers are attracted to tuna baits and cache seeds in nests. Feed a varied diet including mealworms, small crickets, seeds, and occasional sugar water. Avoid overfeeding to prevent mold from seed caching. Remove uneaten prey after 24-48 hours. ^[1]

Temperature and Seasonal Care

Keep the nest at 22-26°C with a gentle gradient, mimicking their mid-elevation habitat. During winter, provide a diapause period by reducing temperatures to 10-15°C for 2-3 months and cutting feeding. Brood appears in April and sexuals in June, so expect increased activity in spring and summer. ^[1]

Behavior and Defense

Pheidole diversipilosa is a dominant ant with high resource discovery rates but is vulnerable to Apocephalus phorid flies, which attack foragers and reduce soldier activity at baits. Leaf litter provides escape cover in the wild. In captivity, add hiding spots to reduce stress. They defend nests aggressively but are not dangerous to humans. ^[2][3]

Colony Growth and Development

Colonies start with a single queen, but founding behavior is unconfirmed. Growth is moderate, with brood in April and sexuals in June. Mature colonies can exceed 1000 workers, requiring significant space and regular feeding. ^[1]
